I know the feeling. I'm a fan of the 100mm f/2 Zeiss Makro Planar on a Kipon tilt adapter. I've never actually tried this, but if you can’t wait until your 600mm f/8 arrives, I could put my 300mm ...

It's very possible. A lot of ultrawides have optical paths that can accommodate insanely fast operation, and are deliberately "throttled" at an arbitrary max aperture to limit aberrations or to ...

It's also, technically, a Nikon "screwdriver AF" adapter, in that it also does the regular AF lenses before Nikon introduced AF-D. (People tend to misuse the term AF-D. About 25% of Nikon's AF ...

And the one everyone else is copying or improving upon. Since I wrote this, five new players entered the game (it appears that SmallRig entered today, or at least their site says shipping today), ...

I agree. I've never had an urge to clip a camera to a body harness or my backpack straps, and the Silence Corner "Manta"/Peak Design "Capture" plates have lots of sharp edged features and are ...

They aren't, unless you get something like a third-party monochrome conversion. There's two good reasons for this. First, the physics: Lens design is an "optimization problem". A lens has a set of ...
-
True. But they basically do it in a foveated image fashion to boost the center resolution of an image, or to improve the image stabilization. Yes, but for different purposes. There are stereo and ...

There was literally no engineering reason Nikon couldn't have made their 50mm f/1.2 lens autofocus. They adopted other similar "unit focusing" lens like the 50mm f/1.4 and the 85mm f1.4 (which has ...
-
Yeah, that sort of thing goes back a long ways. When I designed the first "speed boosters", I figured that lens designers would start building those into lenses, optimizing the design for one ...

An SB-800 weighs a ton for this job (ok, 458g with batteries) and it puts the weight way, way off axis. A reasonably smart flash trigger can tell your camera "hey! We're in flash mode, give us ...

And the one everyone else is copying or improving upon. Since I wrote this, four new players entered the game, and Silence Corner brought out a bigger, badder ATOLL and a line of rotators in black ...

Apparently, it's already a thing for the Sony and Canon equivalents of the FTZ. ULANZI recently brought out rotating collars for the Sony EA5 and Canon EOS-R. Apparently, both of those are nice ...

Indeed. I have a Nikon PN-11 extension tube with a rotating tripod collar. It's quite handy with the old 105mm Micro-Nikkor and with a few more modern lenses. Thanks. I'd hope so. You, me, and a ...
-
Possibly. But that would also reduce the free space between the adapter and the grip. I don't want any sort of motor "bulges" like the FTZ has, because I want mine to include a rotating tripod foot. ...
-
Got distracted by other projects. My current version is too big to fit in an FTZ size adapter, and my algorithm is a bit slow for most uses (although It doesn't read lens ballistic tables and ...

Just watched some spectacular coverage of the SpaceX Starship test flight. My favorite coverage was the "Everyday Astronaut" YouTube channel, and at the end they thanked Sigma for providing all the ...

My Uni-Loc System 2400 goes pretty far above eye level using just the legs. A friend had a Benbo 8. That's 8 or 9 feet high using just the legs, and about 12 if you used the column. Weighed like 25lb.

Hi Jonas. Typically some 20W (150W eq) LED floods with either linear polarizing or circular polarizing film. Circular polarization is both more complicated and simpler than linear. It's complicated ...

Excellent example of the strengths of that technique. Controlled the specular highlights even better than massive diffusers, but you've preserved and highlighted the complex texture. People ask why ...
