Well, the Contax Zeiss 50/1.4 is soft in the corners at f/1.4, but less soft than all the other 50/1.4 I tried, except for the Minolta 50/1.4 MD-III. These are the two best 50/1.4 I used in my ...

Leica R lenses are very good of course but not so exceptional, and it is hard to justify their price and weight. Contax Zeiss? I am a fan. Excellent mechanically: - Never had a problem with the ~15 ...

Did someone compared the new Samyang and Tokinas with old Reflex lenses of the eighties-nineties in terms of image quality? Any input highly appreciated, thanks.

The 55/1.8 was fine on film but lack resolution on digital sensors. The 50/1.4 Pentax has a long history, but you should know that after the M42, the K and the M version, its optics was slightly ...

The Pentax 50/1.4 A and 50/2.0 A are both vastly superior to the Voigtlander 58/1.4 SL-IIs, are lighter and give you the same manual focusing experience. They are better in terms of flare, colort ...

If you travel and want to do many different kinds of photos  - old cities, people, landscapes, wildlife, museum, shows,… - and you need focals (FF or equivalent) between 20-24 mm to 300-400 mm, ...

If true, why didn't they tell me that? One email could have done it - instead, they didn't inform me and I returned the lens.

Nope, no news whatsoever, and I don’t care anymore, Sigma is the past for me.

To pixelpreaching: vignetting is easy to define: it is the difference, in IL, between the corners and the center of the image for the format the lens tested is supposed to cover. (a FF lens...

You are right, except that we should require from manufacturers to make lenses that will not be obsolescent in ten or twenty years. After all, we are the ones paying.

Before digital correction, many modern wide-angle primes and zooms have more than 3 IL of vignetting.

Interesting, but subjectively I feel that my ellipse of clear vision is more the same as a 28-35mm lens on a full frame camera.

For Tamron adaptall-II lenses that don’t have elements bulging outside the mount plane, I have a good news for you: Canon FD rear caps work well!

I was unlucky with my Takumars as well. I had a Pentax K 55/1.8… very nice on films, disappointing (lack of sharpness) on digital 16MP APS-C camera.

So…? Only the MAX is inherently unstable, and requires automatic software corrections all the time. I am stunned that the FAA authorized that aircraft. If there is a software / hardware / sensor...

The software can evolve with time… therefore, a lens that ‘beats’ another one after software correction today could be a loser in, say, 2025.

To Richard Butler: Let's ask the manufacturers to stamp a 'DCF' symbol on their lenses instead: 'Digital Correction Free'. That would be a positive argument to increase sales.

Maybe because it is not true..... Some of the best lens ever have a small number of elements. IMO the software corrections are used to compensate for use of cheap glass and lack of talent of the...

You forget the 346 victims of the 'software-assisted' B-737MAX.....
And I predict there will be more. I never fly on that flying coffin.
Back on topic, I would like to see, in EXIF files and in...

When I read a review of a lens, I am interested by the optical performance of the lens, not by the performance of an external, unknown software that 'corrects' that lens and introduces new...
