Now I understand you better, and I probably should have the first time. It seems worth noting that one can use the excellent Voigtländer VM-E close focusing adapter with the Nokton if you don't ...

Which adapters are breaking left and right?  I have seven adapters, about 30000 images, and they don't seem broken to me.

Yes, I'm sure. It is also verified above by Roger and Stan. Are you sure that the A9 allows 1/3 stops? There seems a paradox here. You're suggesting using ISO = ISO AUTO with M mode. Combined with ...

Thanks for your question. We're talking about different things, so I better be ultra-clear and literal in my choice of words. I'll match the camera's names exactly. ISO AUTO Minimum can be 400 or ...

If any important part of your image is at infinity, I predict you'll find that focusing at infinity and shooting at f/8 will give you an image you like better. You can go through the theory, or ...

All your posts help, thanks so much! Previously, I was confused as to the meaning of "shoot at [...] ISO 640 with ISO Auto." But I finally understand. You mean to use a new A9 setting: ISO Auto Min ...

Looking at the red curve of your graph, we find local maximums at 100, 640, 1600, 3200. Yes, 640 stands out, and we can also see from your graph that 640 is better than 500, 400, 300, and 250, ...

i Just checked on my A7rii, and my ISO Auto can choose every third stop, 400, 500, 640, 800, when I change S or A by 1/3 stop.

[bclaff] ISO 100 is where Low Conversion Gain (LCG) starts. [JF] Sorry, I don't know the operational significance of that. [bclaff] And ISO 640 is where High Conversion Gain (HCG) starts. [JF] Does ...

Apparently, going from 14 bits to 12 bits for continuous shooting seems to incur no real-world loss at ISOs 640 and higher, assuming I properly understand their findings. Also, it appears that good ...

Something in the range of 100mm to 200mm. Manual focus is okay. Ideally with image stabilization. At least 0.5 magnification.

Sounds interesting. Sorry I missed it, but I don't always keep up. Would you share a link to your comparison summary?

I thought this at first too, but on reflection, I don't think it would alter his ranking of the images at all. It would not have changed by rankings either. The framing of the model in all images ...

That's great news on your upcoming video comparing MC-11 to MB!

The photos at the end are drop-dead gorgeous for me. I have a Windows 7 64 machine. I have five Metabones adapters, including a Speed Booster that my wife loves, but today SonyAlphaRumors has a ...

It seems clear to me from your video that the reason you like the 135mm STF over the 100mm STF (both of which are f/2.8) is purely that the apparent depth of field of the 135 is less wide open due ...

Not exactly equal footing, because f/2.8 exhibits more depth of field on an STF lens. If you wanted to try to equalize depth of field with identical framing of the subject (moving the camera, not ...

Magnificent review. Please keep up the great work. Love the format. Very fair style, even though you placed two lenses I own at the bottom of your personal ranking, which you explained is merely ...

I bought my Zeiss 135mm APO f/2 in ZE mount for use with Sony a7r cameras. I think it works wonderfully well with the Metabones adapters. Personally, I usually prefer to have the camera control ...

True, but my images taken with the 100mm STF have the biggest "Wow" factor of any 35mm lens I have ever tried.
