I think, to say that E, or modern lenses are better or far better compared with A mount or other older / vintage lenses is wrong and shallow. I think it depends what you would like to gain with the picture and the used lens for it.

From my perspective modern lenses has a very clinical look, pictures look very oversharped and unreal. In my feeling somtimes also ugly.
Here some examples from a competition - in my feeling overedited and clyinical ugly: https://www.dpreview.com/news/2226209537/slideshow-winners-of-the-8th-international-landscape-photographer-of-the-year-competition

Older lenses has caracter which very often leads to very interesting pictures. - I think, this is also part of the "art of making pictures" to use the old lenses with caracter, flares and failures. - This is, why I am still using and enjoing A-mount with my digital and also film cameras or some old viewfinder cameras.

From a technical perspective sharpness and micro contrast is less compared to the modern lenses. Flares are better correctet. - But, ups - I love flares - also a part of art - I will miss them, so I still need to adapt my old lenses to get this look.
Also vignetation and CAs may better corrected on the moden lenses. But, I can also do it in post processing.
I have also readen several other forums. There was also several test and posts where user posted that the modern Sony A-mount lenses are really in the near of E-mount in perspective of optical quality.

I think the discussion regarding lens quality is very overrated. - The better lens does not make better pictures. - It's the photographer.

I agree the 1.8/50FE is a nice lens, though whether it is any better in IQ than the APS-C DT 50 I don't know. I'd certainly say my 18-55 DT SAM II is better than the E mount version I have, particularly in close-up performance.
I notice changing the in-lens motor from A-mount to E seems to improve AF speed, but lose magnification. I'm assuming this was a deliberate choice to enhance AF speed. Maybe that is a compromise worth doing for many togs, but not me. I don't care much about AF speed so long as the lens doesn't spend ages going to the wrong end of the AF range or dithering about unable to find the right spot. I know in theory CDAF on E should be more accurate that PDAF on A-mount, but I often find the A-mount more reliable in getting to somewhere near the right place.

Anthony, I was referring to the APS-C E 50mm F1.8 OSS. That is a very nice lens especially since it has optical stabilization.

The FE 50mm F1.8 is mostly better too, but it is much more like the DT SAM lens. It is really a very nice classic lens. Others shouldn't think E-mount lacks classic like lenses.

The 18-55 OSS is pretty small and has internal focus. Those could limit its close focus. Most of the older E-mount lenses lacked close focusing. Now high magnification is popular again.

Dotsch, I also find lens sharpness discussions generally pointless unless it is about a particular copy of a lens I am buying directly. Or it is a rental company with many copies and an optical bench that they know how to use correctly.

The majority of commenters do seem obsessed with sharpness. I turn sharpening off on my A7R cameras. I bought the 4K HDR version of Lord of the Rings and find it looks awful because of sharpening. Maybe my TV settings make it worse--I should check that. I also hate Apple's sharpening on iPhones. Please let me turn that off or at least down. I dislike quite a few of these sharp lenses with otherwise questionable image quality that are so often hyped lately. I prefer images from the more classic Sony FE 50mm F1.8 to most of the alternatives everyone else thinks are so much better.

I agree! Lovely lens, underrated imho.

Good points, Mathew. I've not tried the E 50 1.8.
Did you pick up on the conversations about cinema versus TV a while ago? It was claimed that people preferred the slow frame rate of cinema for films, and anything made with a fast frame rate looked like TV? Apparently people got used to the blurring on motion and associated it with widescreen films. I suspect the same is true for resolution. I'm always amazed at the wildlife films they show in shops to show off the big screen TVs, but for people that much resolution is not good. Hollywood used soft-focus lenses for a reason ...
I do agree about over-sharpening, but I take jpegs and sharpening afterwards is terrible.

I sometimes find movie projection to be almost painful to watch. I am not sure why. I did learn recently that they strobe film more than once per frame, but I doubt any film was involved when it has bothered me.

I bought two 55" 4k HDR QLED VA LCD TVs recently after never really owning a TV. 3840  2160 is rather low resolution for that size. The Samsung QN90A is an amazing display. One of the first things we watched was the Green Knight, and the ability for it to show realistic warm sun beams and dark interiors with detail at the same time. The other one is a TCL Google TV with only an 8-bit panel. It is only neat in the fact that it can be used as desktop Android PC. My desktop monitors are so out of date.

I don't know if Sony's HEIF format on the A7IV supports HDR10. sRGB is dead.

Your other point I would agree with for the expensive FE lenses but not the cheap APS-C ones. Sony's A-mount DT lenses are far superior to the E-mount equivalents, if you are prepared to forgive the OSS (which was only added because the E-mount cameras of that period lacked IBIS).
The later APS-C E lenses such as the 18-135mm E OSS seem to be better.

Well, yes, some A-mount APS-C lenses are better then their E-mount counterparts, but that is maybe three lenses? the 35/1.8, the 30/3.5 Macro and 55-200? I cannot think of any other.

Let me rephrase it, most A-mount lenses are not better then their E-mount equivalent and even then the difference usually isn't big and probably not worth the hassle (especially on those small APS-C bodies).

I am not even sure about the APS-C 35mm F1.8 primes. I kinda feel bad I only tried one copy of the OSS prime. The DT SAM prime is not that good and certainly varied in my experience. There are more reliable manual APS-C primes coming from China.

The 55-210 OSS didn't hold up badly to the DT 55-200 SAM in my experience.

The complication of the OSS mechanisms and linear AF motors means more opportunities for misalignment than the much simpler DT SAM lenses.

Never used the A-mount 35/1.8. The E 35/1.8 OSS is not considered the best lens, but I feel it is a fine lens. I checked alignment when I bought mine because like you said, misalignment was a problem with the early E-mount lenses. Sharpness is fine, in general it is well behaved lens. There are better lenses (you mention manual lenses, but others will mention the Sigma 30/1.4 DC DN) but the total package of the 35/1.8 OSS is good: small, f/1.8. OSS and AF. I guess there is room for a mark II version - but as it is, it is really nice on a A6x00 body.

Allthough the disussion on the merits of different lenses might be interesting it's off-topic regarding this thread, which is supposed to deal with the merits and drawbacks of the LA-EA5.

So let's get things back "on topic"



Obviously starting a different thread where the recent discussion in this thread is on-topic is fully OK

Spoilsport!
We've just been having the most interesting discussion on lenses I've seen for a while.
Okay, Re LA-EA5, it's disappointing for those of us with older cameras that it seems to have been designed to work properly only with the newer cameras. But the LA-EA3 at least works well with the DT SAM lenses.
And re the DT 55-200mm, IIRC it is almost a stop faster than the E 55-210mm at 100mm. So many of those zooms run off to their maximum stop as soon as they leave the wide end. Having used both quite often I think it is 'better' but then my judgement criteria different may differ from yours.

It's like the survey that said something like 80% of drivers thought they were better than average, which sounds silly, but could well be true - because their judgement criteria differ. Those of us who like to drive above the speed limit consider our visual assessment and car-control abilities to be important and better than average and over-cautious slow drivers to be a real menace, while no doubt the latter consider the opposite...

I think there are two reasons why the discussion cannot be concluded.
No one has succeeded in quantitatively evaluating AF performance. It is unlikely that anyone will succeed in the near future.
The other is the difference in camera/lens performance. This should be discussed separately from LA-EA5, but it is confused.

In my personal experience, the 99II was much more comfortable than the 7RIII + LA-EA4. 7RIV + LA-EA5 has advantages and disadvantages. 7RIV was advantageous in face and pupil recognition. The combination with 1 was overwhelming, so I sold the 99II and 7RIV (and 9) and replaced them with 1 and GM lenses.

In fact, LA-EA5 has one major drawback when migrating from A-Mount. It doesn't recognize TC.

Recent mirrorless cameras can perform image plane phase difference AF even with F22 (contrast AF is possible if it is higher than that).
F6.3 is usually the AF limit for single-lens reflex cameras, and F8 is the AF limit for recent high-end models.
With the higher sensitivity of the sensor, you don't have to worry about the shutter speed even with a small aperture, and there is also image stabilization. In other words, with a mirrorless camera, you can use a much smaller aperture and more compact lens. Actually, I use ILCE-1 + 200600G + 2xTC, 1200mm by hand. No need for a monopod.

However, A-Mount does not benefit from this. For example, you should be able to AF even if you attach 2xTC to 70400. In fact, 200600G + 2xTC (F13), which does not require LA-EA5, can be AF. However, LA-EA5 and TC cannot be used at the same time. Since it is treated as without a lens, it cannot be stopped down.
If you have 300 / 2.8, you would be very dissatisfied with not being able to use TC.

(There is a loophole that some 3rd Party TCs are not recognized as TCs, but of course there is no guarantee.)

Is what you say about LA-EA5 and TC only true for the Sony TCs? I think these tell the camera they are fitted, whereas other makes just modify the data passed to the camera (or sometimes don't ) I de-chipped a 1.4x TC a long time ago.
The non-Sony TCs do have an advantage this way, though Iv'e not tried them with LA-EA5.

I only have genuine TCs, so I've only seen other people write about TCs made by 3rd Party.

*** Below is my guess. ***

In Minolta's implementation, it seems that both the lens and TC chips are read out and the camera calculates and creates lens data.
The LA-EA5 (or E-Mount camera) does not have this feature.
It seems that there are 3rd Party products that have the same method as the genuine ones and those that TC gives out information after mounting instead of the lens and hides the existence of TC. However, it seems that this information cannot be created correctly depending on the combination.
