That happens when using extensions with SLR lenses on SLRs too. A lens has to be designed to be flat field at high magnification to be flat field at high magnification. Even 1:1 macro lenses which ...

The Samyang 75 is good. There's also some native manual 75's that seem decent. I had actually ordered the Kipon just before the Samyang was announced. I just got the Samyang 85mm F1.4 which seems ...

The Tamron 35mm F2.8 has no more distortion than a 1999 Minolta AF 35mm F2. I just compared them back-to-back. The Tamron is magnitudes sharper. I've only had the older W.Rokkor-HG version of the ...

I haven't seen any pictures of a composite mount failing. I have seen many images of the full alloy mounts on the A77s torn off the bodies. The half composite (A33-A65) and full composite mounts ...

I can't find a Bower branded Samyang lens released after 2013.

Would an automotive journalist introduce a story about the 2022 WRX; "Subaru, also sold under the Saab brand name, will release a new...

I don't get why this site keeps including it. I haven't seen any recent Samyang lens branded Bower. Elite Brands owns the Rokinon brand and claims to have exclusive distribution of Samyang lenses...

The Reflex reports itself to the camera as an f/8 lens. F/6.7 might be more accurate for its actual aperture. A-mount cameras continue trying to focus no matter what the maximum aperture is ...

Only Sigma sold optically stabilized A-mount lenses. Their 70-200 F2.8 OS was pretty good. The Minolta 70-200 was an SSM lens which is a motor abbreviation that Sony still uses, but doesn't market...

Well, that's one thing going for the older GM then. I knew it had a ring-type piezo electric motor in front. I didn't realize it had a mechanical focus clutch like the old A-mount 70-200.

Yes I am wondering if they are talking about what was changed from the original firmware of the LA-EA3 to support faster frame rates on the original A9. Sony seems to leave backward compatibility ...

So you are using a camera that supports AF with the LA-EA4? That makes it likely that the Lens ID check for the Reflex just wasn't put in the A1 and possibly other recent models. It is too bad we ...

No, this lens has only linear AF motors. There is no way this has a mechanical focus coupling.

Canon always had Full-time Manual Focus with their focus-by-wire lenses. Sony's DMF mode emulates...

Prices have been rising on the 85mm F2.8 SAM. I must have sold mine at the lowest point in the market. It is worth something below $200, but it is a nice enough little lens. It uses a very similar ...

Why are Full Time DMF, Focus Limiter, and SteadyShot modes not universal Sony features? Can Sony not implement these in their cameras? They had a universal electronic Focus Limiter in their A-mount...

The center point limit was always somewhat arbitrary. People have put aftermarket chips in their Reflexes and gotten multipoint AF with various A-mount cameras. The cameras just detect the Lens ID ...

This is the only third 70-200 unless you are rounding up some other lens.

No mention of construction? The previous FE 70-200's had issues. The mark I GM used an easily deformed aluminum plate to hold its two halves together. Has this type of weakness been addressed?

Sony "Zeiss" is not third-party unless you're adapting it to a Nikon. Canon is not third-party either except for some much older lenses. The Canon EF 50mm F1.4 has pretty awful out-of-focus ...

It can be helpful for manual focus with colored peaking.
