    Posted: 30 December 2021 at 21:30
I am a design student who will be starting his first internship as a photographer soon. I am also a resident of a rural area where many interesting birds fly into my backyard. I did not intend to be a wildlife photographer but Mother Nature seems to want me to be one. This means that I find myself looking for cheap telephoto glass in ever longer focal lengths. A hawk landed in my backyard the other day. I want to get more zoom than the beercan. But I have heard that Sigma a-mount lenses don't work with Sony SLT cameras. Does this include the SLT adapters for E-Mount bodies?

Some Sigma A mount lenses don't work with A mount film SLR's released after the lenses were made , never mind DSLR's , SLT's and LA-EA* adapters !
That's Sigma for you .

The lens your asking about is one that frequently needed re-chipping .
See here

Try before you buy , or make sure the seller has a good returns policy .

P.S , welcome to the forum .

I don't know about the 400mm lenses but all of my Sigmas work fine with my SLT cameras. I have used 24/2.8, 50/2.8 macro, 90/2.8 macro, 60-200, 170-500, 10-18, 12-24 (both).

The downsides with Sigma are the zen coating (avoid or be prepared to strip it off when it gets sticky) and the vulnerability of the nylon gearing in screwdrive lenses (mine have survived so far).

The Sigma 400s are not well rated (apart from the telemacro) - don't expect beercan quality. Cheap does not make them a bargain - you get what you pay for. At least you won't lose much if the gears strip.

I had the metallic grey version which some sites said would not work with digital but it did on the A700, A350, A550 and Dynax 7d. no idea about slt though, if you can get one reasonably cheap, it may be worth trying

The sigma 400mm lens is from my own experience not worthwhile getting. I would suggest getting the 100-300 f/4 and using it with a teleconverter if needed. A sony/minolta 70/5-300 is another reasonably priced option.

I have no reason to assume the Sigma 400/5.6 will not work with the LA-EA2. My same generation 24/2.8 and 180/5.6 work fine on my SLT cameras. Ask the seller on what camera it was used if possible.

What camera are you using? Do you already have the adaptor?

The Sigma 100-300/4 is a good lens, but quite expensive.
The Sony/Minolta 70-300 is a cheap kit lens. Might be good if you have a good copy.

If you are happy with your Beercan, take a look at the Minolta 100-300 APO - similar sharpness but somewhat better corrected. Or the Minolta 100-400 APO, even better, longer, but more expensive.

Also, have a look at our Lensdatabase: https://www.dyxum.com/lenses/index.asp

I take the chance of this topic as I received a laea2.
Adapting lenses to my a6000 was not my priority, but this can be a way to try to solve my eternal struggle for a telephoto lens. Any advice on a light cheap one that possibly can serve me better than the 55210 If found to have low contrast and washed out colors?

@Barrin: You have the Minolta 100-200 it seems. What is wrong with that one?

I already mentioned the 100-300 APO - not flawless but cheap and good enough.
The Sony 55-300 gets good reviews, it is APS-C like your A6000

If you have a higher budget or different needs, something else might be better.

I'd second ADDY's comment. For a fuller response ...

If you can do without AF then there are lots of film-era teles around that can be adapted with cheap dumb adapters. Don't pay more than $25 for one, except the Tamron 500mm f8 mirror lens (the adaptall one) which is very good but the donut bokeh makes unsuitable for birds in forests ...

Using the LA-EA2 you will get an APS-C crop which is quite okay for long tele use anyway.
I've tried most of the cheaper end of the long tele primes and zooms that will fit an A-mount camera. The AF ones that I could get under £100 GBP and worked best for me (not in any order) are:

1. Sony 55-300mm DT SAM (note that it may not AF with a teleconverter)
2. Sony 55-200mm DT SAM (very sharp and is around f4 at 100-125mm)
3. Minolta 100-300mm (the APO version has less CA in the corners)
4. Minolta 75-300mm (several versions, most of which have strong CA in the corners when you zoom in, so keep small birds/etc in the centre). Great lens for MF.
5. Minolta 75 to 210mm zoom (lots versions; the MFD varies)
6. Minolta 100-200mm zoom
7. Sony 18-250mm zoom

The Sony DT SAM are for me the best of these because they are all very sharp at the long end, all have a usefully short MFD and work okay near it, and you get lens compensations too; however you might have to pay a little over £100 for one. I generally find eBay prices higher than those on Cex and LCE in the UK - no idea how things play out in the US.

If your definition of 'cheap' extends to hundreds of dollars there are more recent lenses available. I'd strongly recommend any of the Tamron 90mm macro lenses (f2.5 or f2.8) which are as good as you'll get in macro for their price and the results will still look good with 1.4x or 2x TC, which is not true of many others. My experience is that AF becomes useless with a 2x TC and is usually okay with a 1.4x. If your camera has focus adjust you may need to check/adjust this for best performance at the FL and distance you intend to use it.

Do not buy any film-era 18-200mm lenses - you will be disappointed. The best Minolta primes are not cheap, the cheap ones are usually okay unless they've been dropped or got fuzzy stuff growing inside them, and the Sigma ones can be great but the affordable ones tend to have some kind of AF problem (broken gear, bent teeth on gear, incompatible electronics, etc).

FWIW I bought the wonderful Minolta 500mm f8 Reflex for slightly over £200 a year ago (in a camera shop!) and that's a terrific bang for your buck... The Donut bokeh is usually an issue on branches close to the bird but not in focus, and doesn't look too bad on those further away.

Thanks for the replies. I don not have the 100-200 anymore. I sold the one I had as it was really soft. Surely a single lens issue.   I should update my lens list.
Quote a lot to think of. Happy new year:)

You found the Sony E mount 55-210 to be low contrast and washed out colours ?

I had one on an NEX 7 and that's certainly not the case .
Did you use the supplied lens hood with it ? It sounds more like it wasn't used and harsh lighting was ruining the image .

As far as what lenses to buy , looking at the lens database would be a good starting point .
But for an APS-C only , low cost , good image quality , the Sony A mount 55-300 would be a good one .

There again a Minolta 300mm f/4 APO HS/G can be had for £400 from Ffordes on their eBay store .
You've a lot of options , but without knowing your needs or budget it hard to help you further .

EDIT ; I've just noticed this isn't a thread you started , so the 300mm f/4 is largely aimed at the OP .
With that and a matched Minolta 1.4X teleconverter they will get far superior quality images than from the sigma .
I owned that and got rid of it .
Even a cropped image from the Minolta 300mm will give better image quality than the sigma .

@ Barrin , perhaps if you started your own thread asking for lens advice , stating your requirements and budget along with the intended use you'll get some good suggestions . Rather than slipping it in the middle of someone else's thread going off topic ?

One thing to note is that the LA-EA2 and LA-EA4 only AF-C in bursts at the Continuous Shooting LO frame rate. I've had good results using some lenses with the later. The HSM A-mount Sigma lenses I've tried have focused better on the LA-EA4 than on the LA-EA3.

The Beercan will AF with generic teleconverters on the LA-EA2 and 4. But it has a lot of chromatic aberration. A 75-300 should be better.

My Sony DT 55-300mm SAM was very sharp though I may have had an exceptional copy. It does AF with Kenko DGX teleconverters on the LA-EA adapters.

My 55-210 OSS was sharp enough. If the only thing you don't like about a lens is it's sharpness, I recommend trying another copy of it--maybe several copies. I haven't tried enough copies of many lenses yet. The 55-210 OSS has quicker AF than any A-mount lens. I used it a little with a Sony front mounted teleconverter that I still have. That isn't a great solution, but it does work.

There are several versions of the Sigma 400mm F5.6. I had the first APO version and have the last HSM version in Canon EF mount. Both worked fine on the Sigma MC-11 adapter. Weak gearing could be a concern with the A-mount versions. The older APO was not that bad optically--sharper than the Sony 70-400 G and Minolta 100-400 APO. Many of these for sale have fungus growth or some other contamination or problem. The HSM Tele Macro is very good. Sigma didn't release an HSM version for A-mount.

Having used both the Sigma 300mm F4 APO Tele Macro and the Minolta AF 300mm F4 HS APO G, I'd say the Sigma had better image quality. I didn't compare them directly though. The Minolta's image quality was worse than more recent zooms I did compare it directly with. Too much chromatic aberration. Not a lens I'd use with converters.

I've been using the native E-mount Tamron 70-300 RXD. I tried a couple copies. The one I kept is not as sharp as my former 55-300, but it is alright. Autofocus has been great, unlike their 28-200 RXD or LA-EA adapted lenses.

If you really want a long lens the FE 200-600 G OSS with the FE 1.4X is worth investing in. I've used it a couple of times without the converter for soccer games. It is a pain to carry though.

Thank you to everyone who posted and to everyone who welcomed me to the forum. Thanks to your advice I have not bid on the 400 mm. I bid unsuccessfully on the 170-500, and am now looking at the Tamron 200-400 mm.

I had the Sigma 170-500mm lens years ago and was very disappointed with it .
I bought it to use with my Sony a100 and even on 10mp it wasn't very sharp .
Maybe modern , higher end cameras with micro focus adjust could make better use of it , I don't know .
But I think it's good that you didn't win it .

I assume you know of our lens database and review section ?
