Why do the Fujifilm GFX cameras not have a touch screen based shutter activation function like the Fujifilm X-series cameras do? Shouldnt GFX have more features rather than less? See the presence ...

I recommend a tripod mount ring (available on ebay for ~$80) for the 19mm PC-E. This allows for movement of the camera rather than the lens, which eliminates parallax issues when stitching shifted ...

@Mr Bolton You would rather shoot at ISO 2000 than ISO 8000, why? Because you prefer seeing smaller numbers but don't care about noise? Have a look at DPR's Studio shot comparison tool, notice that...

@Mr Bolton Or you could just increase the ISO two stops on FF and get two stop faster shutter speeds. It would look the same.

No they are not. Look at the Voigtlander Nocton 50/1.2 for example.
Or their 29/0.8 if you prefer m4/3.

Adapting from Z to E is not possible due to the flange distance, just as this E to Z adapter is only 2mm thick, a hypothetical Z to E adapter would need to be -2mm thick (or incorperate additional...

This Canon is not an internal zoom.

IS is actually better than IBIS for correcting motion in the edges/corners. Having both working together is the best solution.

Not $500 too expensive, more like $200-300. Nikon's 14-30/4 is $1,300 (though currently on sale for $1,100), and this goes to 35mm and has IS in the lens, so $1400-1500 would have been reasonable...

This is great work. I am interested to see your methodology eventually, as it sounds like a difficult job. I am probably asking for too much to also see some version of these tests for off-axis mtf.

If I set the front command dial to +<—>– and the aperture ring to A mode, changing the camera to f32 locks it at that aperture and the only way to change the aperture from there is to reverse the ...

The focal length options are only designed for Nikon lenses. The 86mm focal length is for the long end of the Nikkor 43-86mm f/3.5. Nikon has never made a 90mm lens (for digital or 35mm film), or ...

The same principle of spherical aberration control has been used in the Nikon 105mm f/2D DC, where DC stood for "defocus control".

The mtf charts Sony presents show it to be sharper than the Nikon and Canon 50/1.2 lenses too....

That is what I mean, NISI claims that their replacement hood "limit[s] the light leakage that results from the [Nikon original] HB-97 lens hood". Whether NISI are a high quality developer is ...

The filter does not cause the light leaks, it is the gaps around the inner edge of the HB-97 hood that let light in. Other lenses have threads directly on the lens in which the filters screw in.

Well neither am I 100% certain as I don't own the 14-24/2.8 S due to the likelihood of light leaks being too high in my estimation to buy one to test. I opted for the 14-30/4 instead as light ...

The Nikon HB-97 lens hood when fitted to the 14-24/2.8 has gaps around its inner edge. Light enters from the rear and reflects off the filter. This is why NISI has designed a replacement for the ...

The Nikon 112mm filter hood will cause light leaks with ND filters. The 100mm adaptors such as the one from NISI are a better solution if needing neutral density.

Use RawTherepee for photos that are ruined by Z6/Z7 banding, use whatever else for all other photos.
