positive:Super Sharp
Lightning fast and quiet AF
Military Built quality
Weight balances the A700 well
negative:Price when new more expensive than the OEM lens
Weight not useful for all Alpha range

comment:I had the DT 50 1.8 and though it was a very good lens in optic quality. i wanted something faster and solid built for my A700. I purchased this lens in mint condition used for a great price. A lot of glass with the lens and it also comes with a nice bag.

Well all i can say is that i cannot part with it now. Its a super fast prime and great for indoors. Very sharp on all stops. The bokeh is the best i have ever seen.The HSM motor is silent. This lens looks very professional on a A700 body n also the Full Frame cameras. This lens along with my SAL18-200 & DT 30 macro is all i need right now.

Edit- Mines a 2009 copy and am using it now with my new A77. Works perfectly without any errors. No software updates or rechip done

comment:This one was everything I wanted. It is sharp right from 1.4 and only gets better stopped down. Focus is quiet and accurate. Nothing bad about this lens, maybe the Sigma colors compared to Minolta/Sony.

I would buy again.

comment:Bought this lens about one month ago. It isn't dissapointing at all. I had to choose between the sony 1.4 and this sigma. I chose this one, mainly because of the high build quality and the big lens opening.
Never tried the sony, did play around a bit with the minolta 1.7 tho.
In indoor without flash this lens performs great!
Even with relative low iso (200-400) it does very well, it should, because at iso 800 my a300 is quite bad imho.
I haven't regretted buying this lens and I think I never will.

positive:Amazing sharpness, Quick and silent AF, great build
negative:not totally sold on Sigma color but im nitpicking
comment:Wow, I had a mega trade and this little beauty landed in my lap with a Zeiss 135mm 1.8. Simply an amazing lens with tack sharpness and quiet lightning AF. It's built like a tank and works nicely to offset the weight of my A700 with VG. I loved my Minolta but this little darling has quickly filled the position. As a whole, I don't care for Sigma colors but I can overlook that minor detail due to the outstanding performance of this lens. Really, I'm just nitpicking at this point. If your thinking about it, get it.

positive:Sharp at F/1.4
Incredibly Sharp at F/2.8
negative:Huge
Heavy
Only stops to F/16
Minor Flare Problems
comment:This is a great lens for low-light situations. At F/1.4, images are crisp, clear and very, very usable. At F/2.8 it gets even better.

It only stops down to F/16, which isn't a problem most of the time, but it would be nice to have that flexibility.

The HSM is quick and responsive. The focus ring is well-placed and wide, making it very easy to fine-tune focus.

This lens is built like a tank, and weighs about the same. It's much heavier than other, larger lenses (Sigma 15-30mm, for example).

Even with the lens hood, I've had issues with flare, probably because of the huge front element. It's not terrible, but stray light (street lights, neon signs, etc.) can cause distracting flare.

EDIT (10-21-2010):
I've now had a chance to use this on the A850. At F/1.4, the sharpness in the corners suffers noticeably. But at F/2.8, it's as close to flawless as I've ever seen. Also, after using it for several months, I can say that the weight isn't so much of an issue. It actually balances the camera very well, and is a delight to work with.

comment:Good resolution, good focusing speed (and silent focusing). Build quality is good enough even if it does not compare with my Sony lenses (even the 50mm f/1.4 feels more solid to me). I find it easier to focus accurately at full aperture than the Sony 50 mm f/1.4. Cannot comment on flare control really but I never noticed any in my pics taken with this lens.

negative:Nothing IMHO.
Price is fine for what you get!
comment:This lense is awesome. It has the second best bokeh I have experienced so far behind the CZ 135. The weight, IMO, is a plus as it adds a since of balance I enjoy on my 850. The HSM on my copy is very fast and accurate. I got a very sharp copy right out of the box. This was confirmed by a second Dyxum member after I let him borrow it for a bit. :)
For the price, I truly feel like I have similar quality to CZ or G rated glass when using this lense. I only hope the new Sigma 85 1.4 brings the same to the table.

comment:I tested recently this lens on a A900 and it's really amazing, bokeh is just superb, focus speed is ok, not as evil but not slow, in any case it's absolutely quiet. The lens is big, really big, it suits fine on a A900 but it's too big for a A200. The build is good, it's not a G but it's good, sharpness is also good, specially wide open, no disturbing distortion at all and no flare at all.

positive:High contrast wide open

Excellent at distance
Focus shift less of a problem than other Planars
Very little vignetting

Bokeh is unbeatable
negative:Autofocus is not 100% accurate
High contrast - can blow out highlight detail
Bit of CA at wide open - usually a green fringe
comment:I didn't like my first copy on A700, on crop the combo didn't have the resolution to give nice sharp pics. So I stayed with 35/1.4G which is sharper.
Now that I have switched from A700 to A900, I sold the 35G and bought the Sigma again. The high resolution of the A900 makes the best of the Sigma, which is never going to be crazy sharp at any aperture.
The colours are surprisingly good for a Sigma lens, warmer than Sony 50/1.4, a bit less saturated than classic Minolta (e.g the 50/3.5). Contrast and colour and sharpness are not quite at the CZ85 level but I prefer this focal length. On reflection I think that even the old Sony Minolta 50/1.4 is sharper than this Sigma, especially in the centre, but the focus shift problem of old standard lenses has always vexed me, and I don't like the lack of contrast, flare problems and AF at distance on the old Sony standard.
Build is Good. It is satisfying to use, but you have to keep an eye on highlights, and check AF is working. The lens cap materials are nasty but the zip case and hood are good.
Would I recommend it? Not on A700. The sharper 35 and 85 primes deliver higher resolution. But on the A900 this lens comes into its own, it is the right size for a full frame camera and causes me very few problems. Also the colour cast I saw on A700 has gone away now.

For low light it is totally usable wide open. For portraits at any distance it is Excellent. For total sharpness or for closeups with good control of contrast I switch to the Minolta 50/3.5 Macro when necessary.
This is my favourite lens for low light portraits with amazingly smooth bokeh - possibly the best of any 50mm lens ever - and a flattering balance of sharpness and softness.

-Great lens and feel pretty in the hand...
negative:Ok from f2..
Big filter(s) needed 77mm
Problem in combination with HVL-F58 AM
comment:From all the 50mm's f1.4 the biggest in outside dimensions
....filter size = 77 mm
But feels good on the body, in combination with the support hand ;-)
Nice from f2....
This lens has a little bit frontfocus but the same as the Tamron 28-75mm 2.8 ...and just in the limited zone..
Lovely DOF by the 9 aperture blades....
Its stay mostly on my A700 body!!
Update 3/2010 Problem in combination with HVL-F58 AM = overexposure of +/- 2 stops.....without flash it's not that much...

comment:I bought this marvelous lens for available/low light photography. On the A700 she is a light tele lens (ca. 70mm). Very usable as portrait lens. Stopped to f/2 and this lens produces very sharp pics. In the range between f/1.4 and f/1.7 the pics are sharp. I like the AF/MF switch on the lens.

In comparison the Minolta 50mm 1.7 produces much softer pics. Also the AF speed is slower on the Minolta 50mm 1.7. And it makes much more noise (no internal AF motor).

If you in need of a fast (F1.4 & HSM) and quiet lense at this focal length the Sigma 50 F1.4 EX DG HSM should be on top of the short list.

The Sigma is not my first lens with a filter diameter of 77. So this was not a problem for me. I have big hands, so i like the size. But i can imagine that for some people the Sigma 50 F1.4 EX DG HSM is to big. You are getting a lot of glass with this Sigma.

comment:Think I'll have to consign my kit lens to the bottom of my camera bag now I've got this baby! I was torn between this lens and the Sony 50/1.4, and I'm glad I picked this.

The bokeh is fantastic! Performs very well in low light too, as you'd expect of course. Occasionally it briefly hunts for a focus lock on difficult subjects, but what 50mm doesn't?! Mostly the focus is very fast, fairly accurate and silent.

Some may not like the size and weight, but I like it, it gives it a feel of quality and longevity.

The only downside really is the price - approaching Ł400 for a 50mm sounds a bit steep to me.

Overall, an excellent lens, and one I'm gonna get an awful lot of use out of!

comment:A fantastic lens that is an absolute joy to use. It rarely leaves my A850.

Optically, it is a killer. Very sharp even towards the edges of the frame, but more importantly, it produces the best bokeh I've ever seen from a 50. The only bad thing I can say about the optics is that it can flare under very predictable circumstances, as with all other 50s, but the flares are reasonably benign and don't wash out the entire image.

Focusing is nearly (but not completely) silent thanks to the ring-type HSM, and it allows for full-time direct manual focus. It has a wide and well-dampened focussing ring that is very comfortable to use.

The build quality is just as excellent as with all other Sigma EX lenses, with some kind of composite barrel and a large petal-shaped hood that (unfortunately) takes up a bit too much space in the camera bag. The whole lens is huge compared to the alternatives, but very well-balanced on larger bodies such as the A850.

comment:This lens is brilliant!
It's delivers everything you'd expect from a lens.
Don't worry about the fact it's a fixed focal length lens, you'll get used to it, and you'll prefer it above zooms!

comment:This lens just astounds me! I dont really know what else to say about it. Ive had some time to go around and shoot with it. I do not hesitate to shoot at 1.4. But the subject needs to be a good distance away of coarse(very thin DOF). This is my "go to lens" for portraiture(F2-3.5). I used to use my Super multi coated Takumar 50mm 1.4...yea...it has been replace by this lens. Its big...But....I just really dont know what else to say... have no negatives besides the filter size. But I guess if I buy an ND filter for it, I can use it on my 70-200 as well. Its build is great. Its just a great peice of glass. The price Is a little steep. But I think its worth the price! I will find many uses for this lens that i have never had before!
Compared to my 24-70 at 50mm...By F4 the extreme corners become sharper then the 50mm. But I dont think I will ever even use this lens above F4 ever. I bought this for the F1.4-3.5. So it really doesnt bother me at all. The center on the 50mm is sharper then the 24-70 at 50mm at all apertures.
If you read a review about this lens. Then you know exactly what your getting. A GREAT low light/portraiture lens!


I really dont even want to put that I compared it to the KM 50mm 1.7. I compare 2 shots and...after that there was no other need. Not that the KM isnt a good lens. For $100 I guess its good. Its good for beginners that want to experiment with DOF. Beyond that...yea.

positive:Great bokeh, compared to other 50s.
Quite sharp.
A new design (not just an improved one).
Silent focusing.
Focusing is pretty fast and accurate.
Internal focus.
negative:My AF stops working when I shoot in the hot open sun (maybe a defect on mine?). It's back to normal after a while in room temperature though. And it's not THAT hot.
Heavy.
I hate the finish on the lens, rubbery material that wears off after a while. It peels off actually.
comment:Its a nice third party lens, great price, great results.

The only thing I hate was when I was in Singapore, at around 13pm, the lens stopped working because it decided it was too hot. The lens when touched was hot, but the heat didn't kill me, because I wasn't wearing caps or anything at all. I think the heat was still normal, albeit it was hot. Maybe it's just my lens?

It went back to normal after a moments rest in the shade though, but then again, I don't expect my lens to stop working just because of heat no? How do people take pictures in the middle of Sahara anyway?

The bokeh is probably the nicest I've seen, very smooth and even.

I love the 77mm thread, but it's heavy.

Would I recommend it? Maybe, but I almost decided not to buy it just because of the body material. I hate it when it peels off. But for quality wise, in it's price class, and it's range, I think it's a very nice lens.

Kudos for Sigma in making a brand new design for a 50mm standard.

comment:Lovely to be reintroduced to the joys of a 1.4 lens after a long gap since my Canon A1 days. Superb lens unless you are one of the brigade who seem to think 500g is a heavy lens. Lovely all round, as sharp as the legendary 35mm F2 and a great ever so slightly warm look to the colours. Bokeh is creamier than a pint of Boddingtons.

comment:I can't say how much I enjoy this lens. I have taken it on a street walk or two in New Orleans, used it at a wedding, and have taken it to the aquarium. It impressed me in every since application that I used it in. The bokeh is delicious! I would buy this lens again for sure if I had to do it again!

compared to:- Minolta 50mm f1.7/1.4
- Sony 50mm f1.4

positive:- build quality
- focus speed and accuracy
- size (I'm a fan of bulk)
- IQ wide open
negative:- slight purple fringing wide open, but only visible on unrealistic zooms or crops (only pixel peepers will notice)
- only goes to f16
- EXIF thinks its a Tamron lens
comment:The build quality of this lens is amazing. Its solid solid solid. It also has a "felt" type surface to it, instead of metal or plastic. It is very pleasing to handle.

I love the size. I always felt my Minolta 50mm f1.7 was dwarfed by my gripped A350, but the bulky size of the Sigma is perfect. Love it!!!
The HSM is quiet, fast, and accurate. Louder than my CZ2470 or 70200G, but much quieter than the body screw drive.

The only downside I can see is the smallest aperture is f16.

Small white alignment spot instead of bright unmissable orange dot. Some weird decision imo...
comment:I was waiting for this new lens to be available in Switzerland before buying my next camera. It´s finally (also) here. Comparison with my old Minolta 50/1.4 might be too subjective - it broke beyond repair years ago - as relying on memory and old film positives, but I expect this one to be the standard lens on my α900, just as the minolta 50 was on the 7000i and 700Si. On α100, I carried the Sigma 20-40 as standard mount, a lovely zoom on APS-C, but this one clearly outperforms it at almost the same maximum focal distance. Not to mention the difference in weight, can do with some compensation for that of the flagship.

Compare it with the three kitlenses mentioned above? Oh, well, I´ve put them there because their range covers this 50mm prime, but that´s where it stops. I never used either very long.

On the α100 it will behave like a nice short tele (portrait!), and made me discover the SSM feature of that camera. Never knew that - just finished reading the specs again, could not find it, must be hugely overlooking - thought it came with the last top models... A shame as we could have had ultrasonic lenses much earlier then; especially thinking of the ZA 85 / 1.4 and ZA 135/1.8 here, no to mention Sigma´s efforts!

comment:I have this lens for my A350 purchased and was surprised that they are sharper and faster than the Minolta is.
With the new A900 are also the slight distortion disappeared.
The Sigma is next to the Carl Zeiss Vario-Sonnar T * 24-70 F2.8 ZA SSM my favorite lens.

comment:The 50mm f/1.4 used to be my primary lens on APS-C for portraits and I reached out for this lens intead of the 85mm f/1.4. With the FF, it lost this status and became more of a "for everything else" lens (see the "compared to section" to understand what I mean). If I was going on a vacation, this would be the only lens I take with me.

comment:This is a fastest lens I own. Everything seems to be ok with it. I was bit disappointed when I compared it with my sharpest lens Tamron 90/2.8, contrast and sharpness are not in same level with Sigma (even stopping down to 2.8), different class though. HSM feels great while it isn't totally silent you can get hold on what af is doing, it's still silent enough to be unnoticed. Seems to be quite tolerable to flare. I have to still take it into action to see real capability.

UPDATE: A700 seems to be in trouble focusing this beast. I think that this is something to do with contrast detection. I have to check focus and not trust focus confirmation blink. So no action shots, bummer. Still I must check if af-priority mode can make it better.

Bokeh seems to be very creamy at 1.4, maybe too much but I can live with it ;-)

negative:Not that it bothers me, but its pretty big.

comment:Very impressed with this lens. Bokeh is very smooth and creamy, and this lens is more than usable wide open.
The HSM is quick and silent. Not as fast as the CZ 24-70, but just as accurate when tracking.
I'm going to get a lot of use out of this lens.
