I've been using several Metabones adapters for a long time. They didn't work at all with one of my off-brand EF lenses, at least not with the initial firmware. I've used the Metabones adapters for ...

I've had delightful success with AF converters in difficult situations, such as with the Canon L zooms for Fisheye and 200-400. I see no reason to rule them out.

Here's maybe the best list of fine options that don't break the bank: https://phillipreeve.net/blog/affordable-manual-lenses-for-the-sony-alpha-77r7ii7rii-and-7s/

My main draws for MF lenses are these: Voigtlander, size and weight, haptics, sunstars, choices. Want something from the recent ground-breaking Voigtlander line? It has to be MF. For example, ...

I see what you mean.   I checked, and it looks like you are completely right.

Thanks, but I was talking about Loxia, not Batis. My guess is that Batis is probably less robust due to AF, the extra window, etc. Anyway, Batis is different from Loxia. Loxia lenses are so well ...

Interesting.  I don't really understand exactly what weather sealing promises in terms of when it is raining or dust is blowing.  For example, do I need a UV lens?  Do I need to keep the lens ...

For hiking, the Voigtlander Nokton 21mm f/1.4, or the Zeiss Loxia 21mm f/2.8, is a much better choice, in my view.  I have both right now, and I might choose the Loxia for weather sealing and ...

Thanks again. Sounds like we can assume that Sony has said nothing about the Zeiss Batis line of autofocus lenses, or the latest Samyang AF 85mm f/1.4. My guess is that they will also work at ...

Thanks!  Can you tell if that includes third-party E-mount autofocus lenses, or is it just about Sony autofocus lenses?

What's a translation for the last line in the table?

I suggest a few controlled experiments, and tell us or show us the results.

I like your images very much.   I'll have to try your technique myself. As for shifting, what Canon does with their TS-E lens is to allow a shift up by 12mm so that the horizon is at the bottom of ...

Yes I like panorama aspect ratios as well. If you remove the top and bottom thirds from 3:2, the result is 3:(2/3) or 9:2. But your examples are 3:1, and if you always do this, then it looks like ...

The Canon TS-E 24 mm f/3.5L II is another option.  Though possibly a minority view, I consider the latest Canon 24mm TS-E more versatile than another lens that includes 24mm. Shifting and tilting ...

Unless I really need AF, I would prefer the recent, amazing Voigtlander 21mm f/1.4 Nokton Aspherical for its superior image quality for most subjects, far better weight and size, arguably the best ...

At a risk of repeating myself here, the question for landscape shooting is always the coverage when focusing at infinity, which is generally less coverage than at other focus distances, so the ...

I'm not sure what happens with internal-focusing lenses, but for other lenses, the image circle is smallest when focused at infinity. This happens because the front of the lens moves forward when ...

Not exactly.  Using a glassless adapter does not change its focal length or its depth-of-field characteristics.  Even if an adapter leads to the possibility of greater magnification through ...

If you measure depth of field by where the sharpness has fallen clearly below the plane of sharpest focus, then the lower the quality of the lens, the larger the depth of field.  Let's call this the ...
