"Made to provide power to dummy batteries"? It's unlikely that any of the various Chinese companies that made those generic power supplies ever saw a "dummy battery". One complication is noise. Ano ...

On a weird note, today Feedly gave me this link to Nikon Rumors about that particular lens (literally, that lens: the serial numbers match) being on eBay. https://www.ebay.com/itm/Modded-NIKON-PC-N ...

My house is visible from the sidewalk. The interior of that club isn't. On that, we agree. That's always an issue. Remember "the bean"?

You own the copyright on that image. You can't do much commercially withou releases from the band and a "property release" from the club owner if recognizable features of his club appear in the ...

Often not big enough, but not "always". I have a 55mm macro that has a pretty good field to a 25mm radius at infinity and 29mm at 1ft,

Thanks! I've been considering one of the passive E to Z adapters. Nikon to Sony to Nikon again. Although I do tend to favor name brand adapters.

I'm waiting for the K-3 III three iii tertius.

My 35 f/2.8 is slightly newer than your 3.5, but my 28 f/4 is older than your 3.5. So, which one did you get? Or are you going to keep us in suspense? I think I posted my thoughts on this last ...

@MikeRan, it's incredible how much you can tell about the way that a sensor that overhangs the substrate is mounted.

@mandm - He didn't read, or look at the pictures. ;) Like I said, two finger-widths high.

Every 5-10 years someone pops up with a curved sensor. Last time it was Sony.

Same problem, every time: it's not commercially viable. The sensor only matches one lens, so it's only useful on fixed...

@MikeRan, Are you going to call CREOL and tell them that their flexible curved sensor has to stop working?

@David Franklin - The goal is to curve the sensor in whatever direction a particular optical design requires it to curve. That's basically what keeps this from being a commercially viable product...

Yes. It would pretty much require a dedicated lens line, or cameras with fixed lenses. Then there's the problem of the optimal curve being different for every focal length.

The fixed lens FF...

You're ignoring adapters with optics, which have been shipping for years from several manufacturers including Metabones and Fotodiox.

> It is also the reason why you can't use an E-mount lens on a...

The one pictured is two finger-widths high, so yes.

It's "getting popular" in many different hobby worlds, because few people ask a hobbiest to justify your hobby. They don't ask you to justify your model railway, and if adding a 3D printer to your ...

You won't change his mind, Doug. No one ever asks golfers, foodies, gym rats, stamp collectors, woodworkers, etc. to justify their hobbies. That's something that seems only to happen to ...

Along with the square, the shaft, and the spiral. Squares have better edges. Triangles, Penrose tiles, there are a ton of ways to fill a plane with equal size shapes. No, they're just convenient ...
