Rol Lei Nut

My previous post was intended as a tongue in cheek response to the brick wall images. Now that real images are posted, using very nice light and composition, that post is seriously off. Sorry!

Here's a recent thread from the adapted lens forum: https://www.dpreview.com/forums/post/61798555 If the prices are similar, I'd go for the A7II because of IBIS. But here is a previous post I made ...

All adapters should be checked/tested for geometric accuracy once you have them. Even more so in this case, as you're effectively stacking two adapters. Just do a test shoot, preferably using the ...

I'm usually not a great fan of Fotodiox products. Among the inexpensive accessories and adapters, I've had better luck with K&F Concept or Neewer, for example. That said, the Leica R to Leica M ...

It looks the same as the one I used, though that doesn't mean it's from the same manufacturer, etc. In any case, ALL adapters should be checked/tested, even expensive ones: - look through it ...

I find that the A7 is still quite acceptable at ISO 3200. The A7III undoubtedly will do better, but the A7 certainly isn't bad! No. For several months I used a dumb adapter as you describe, with ...

35mm film cameras took 24x36mm images (with very few exceptions, which were then called "half frame" or something similar). A digital sensor of that size is now called "Full Format" or "Full Frame". ...

IF the mirror itself really is perfectly parallel to the target (been there, done that)... Again, the Gletscherbruch method has given me the most repeatable results of any, with little fuss.

Lenses tend to do better on the format they're designed for, especially wides! If you're using good lenses, the argument that cropped cameras are using the "best part" of the lens doesn't ride. Aft ...

Generally speaking, I'd call it a great idea for using adapted MF lenses. The things going against the A7: - no IBIS. IBIS also helps a lot when focusing longer FLs, not just shooting in bad light. ...

I use an M42=>Rollei adapter, then Rollei to <whatever>. The advantages are: - the M42=>Rollei adapters are very thin and light (and used to be o.k. cheap), so keeping one on each lens isn't a problem.

It's a very nice lens. Main disadvantage is that, like most 70/80-200 zooms, it's physically long and won't easily fit into smaller bags/pouches. Curiously, most 70-300 zooms are actually shorter ...

Actually, it really could. That does go against theory (and most practice). Mysteries of lens testing....

Using cheap adapters can work fine, as long as they're geometrically correct and don't introduce reflections or light leaks. Using them without testing is a lottery, though. I use many expensive ...

????? You apparently thought I was advocating using equal corners for the purpose of finding the camera alignment. => I meant checking if the corners are *equal* after shooting a Gletscherbruch ...

+1 For indoor tests of that type, I've tried to align the camera using: - precise measurements with tape or laser rangefinders - a variation of the above, with carefully contructed geometric ...

Also, use the Gletscherbruch method for testing, as it will (mostly) eliminate alignment errors.

Does your Nikon 28 2.8 have floating elements? If so, focus on something far away: what does the focusing scale show with the two adapters? Adapters should be checked and tested as a matter of ...

Basically, who cares? Some people act like paranoid schizophrenics when any possible (implied or deducted) criticism might possibly be aimed at THEIR brand. Leica's CEO could publicly announce that ...
