Completely false. I get AF still working with a Minolta AF 100-400mm F4.5-6.7 on a Kenko 2X teleconverter with the zoom at the long end. It will just barely lock if pointed at something like a ...

The best deal is a late Minolta AF 50mm F1.7 "RS". I have a very sharp one right now that does have a focus bind problem. You can get the earlier AF version slightly cheaper or the original manual ...

I like my Sony DT 55-300 a lot. The adapter doesn't affect IQ. The AF is fine--it is not a particularly fast AF lens. Sony has also limited AF features with LA-EA adapters on the A6500. I use the ...

I'd say get another 24-105D. I like my current one. It is small and light, and reasonably good. The older 24-85 is cheaper and a bit better on the wide end.

How many lenses do you consider lots? I have around 100 right now. I have never taken all my lenses with me anywhere even when I only had a couple. I normally just bring one lens on a camera, at ...

It probably won't happen. A-mount cameras don't have automatic focus magnification at all. Yes, you should get 3-axis stabilization with any A-mount lens with electrical contacts. The focal length ...

SAM lenses don't respond to any camera's AF/MF controls. The only exception is the 18-135 SAM which does--it acts just like an SSM lens. SSM lenses allow DMF at any time on any body. But they ...

No You have to use a button/menu for focus magnification. Focus-by-wire seems to be required for this feature. The only focus-by-wire A-mount lenses are the Xi Power Zoom series which aren't ...

I'll suggest the 18-135 for more reach and better AF. It is basically an SSM lens in all but name. I have no experience with the Sigma. The 16-80 varies quite a bit, and it is quite short at 80 mm ...

The main difference between the 16 and the 16-50 at 16 is distortion. The former has less distortion than any other lens I have had at 16 mm. The later has a more distortion than any other lens ...

Kenko DGX teleconverters work fine on my LA-EA1. They might have some issues with the LA-EA3 and the latest A-mount lenses as they don't (fully?) support the latest A-mount communication speed. It ...

The LA-EA3 only works well on cameras with OSPDAF and Sony has enabled it with adapted lenses (updated A7II/III, A7RII/III, A9, A6300, A6500). Many E-mount cameras with phase-detect don't use it ...

Probably not a bad choice. I don't know much about Nikon full-frame, but I see reviews mention that the D610 AF isn't great in low light. I have tried their DX models with that 39-point AF sensor ...

The LA-EA4 is more expensive than many A-mount cameras. It performs worse than the cheapest SLT cameras. Why not get one of those instead? My A68 is better with A-mount lenses than any of the ...

That's what the mini lens with the awful field curvature looked like. It was useable wide-open. Maybe they are purposely designed with the curvature for the effect. The larger 35mm F1.6's might be ...

I tried a Kaxinda 35mm F1.7 which is what Meike rebadged. It was awful--maybe a bad copy. I've tried a mini C-mount 35mm F1.6 lens which was horrible (the mini C-mount 25mm F1.8 was horrible too.) ...

Yes, all the Sony LA-EA adapters on all E-mount cameras only support AF-C at the slowest stills burst rate (2.5 of 3 FPS). The only exception is with an updated LA-EA3 on the A9. You do get video ...

Photonstophotos maximum PDR

A7R 11.71
A7RIII 11.65
D850 11.63

At least by this measure Sony achieved better DR than the D850 at ISO 64 back in 2013 with the A7R at ISO 100.

I recently picked up a MD Rokkor-X 50mm F3.5 with 1:1 extension. This one is nowhere near as sharp as my 1995 Minolta AF 50mm F3.5 which was also much cheaper. FWIW: the AF 50mm F3.5 is second ...

I know this question is from several years ago, but I might as well answer it. You can use anything to extend the lens to get to 1:1 or beyond. You could hand hold it or use a cardboard tube.
