Go for it. In terms of bang for buck, adapting old lenses will give you more of it than their modern-day counterparts, almost every single time. I have a lot of Olympus OM, Contax, M42, etc. lenses that I use with my digital cameras all the time :)

OK, now I get what you're saying, you're giving the "135 format equivalent" which is ~53mm. Which is just confusing in this context because the Kipon lens isn't giving you an "equivalent" value, it's 40mm is 40mm is 40mm. That's why I didn't give you an "equivalent value", the FD55/1.2 + SpeedBooster is going to…

You have your calculations wrong. Multiply 0.71 to 55. Voila, 39mm.

Your understanding is incorrect; the camera (e.g., NEX) will not "recognize" an F-stop that is faster than F1.0; so it'll pose a problem when trying to automatically control the F-stop of, say, the Canon 50/1. But the light is definitely being gathered, and you are definitely getting that much more light, and indeed,…

This is really no surprise with mirrorless cameras. Even today, if you pick up a (1) Canon EF 50mm F1.0 lens and (2) Metabones SpeedBooster, you will have a combo that acts like a 36mm F0.7 lens on a Sony NEX. The 50/1 is expensive, so instead you could get any of the cheap-ish F1.2 50~55mm manual lenses on Ebay…

Of course, your model only works if you decide to observe the movements of the earth and the Moon not relative to one or the other but absolutely.... relative to the barycenter. However, why draw the line between relative and absolute there? After all, the barycenter of the Earth and the Moon moves, too (orbits…

Those designs are nice, in that I like wood and I like retro, but none of those will fly; if the designer paid Apple to use his design, they'd reject it, because (1) people who like wood and retro are a niche; those aren't designs that sell to the masses, and more importantly (2) industrial design is always so much…

It's slow, but it works; at least with the one and only AF EF lens I have (17-40F4L)

Mk1 and Mk2 won't work. No issue with the Mk3 adapter; there's no vignetting even with the TS-E 17mm, which I was worried about. Maybe when using really long lenses, it might be a different situation (I know, e.g., SpeedBooster had an issue with lenses longer than 120mm or so). The longest lens I have is 135mm and…

Already got mine (A7R) :) Sold my 5Dmk2 and NEX-6 to buy it, too, and I don't see myself regretting it one bit. I did purchase a Metabones EF-E Mk3 adapter to use the one Canon lens that has no equal: TS-E 17/4L. Good times.

All these moments, not yet lost.

OK, the fish is complete bogus. Everybody knows fish can't survive on land.

Use the force, Luke...

Sounds like a contraption well suited for a new episode of Scooby Doo

As long as the numerator remains constant while the denominator grows, these "old people with old ideas" will matter less and less. So while they may not biologically die, they will die out socially.

For me, I must say "Neuromancer" that was never made because JM sucked ass and Gibson threw a fit. Or so I heard.

I think I'm gonna go with this selection as well.

Was there ever a LoTR movie before Peter Jackson's? I know there was a Hobbit film..

Not to debate whether or not a trackpad is best for *all* computing activities––there probably are plenty good reasons why you'd want a mouse for gaming, graphics, etc.––but for *general* computing, I can't live without my (Magic) Trackpad + BetterTouchTools (OSX). I enjoyed my MBP trackpad so much that when Apple…

Yeah, but that's activity-specific. It's like saying "Yeah, try drawing without a Wacom tablet". It doesn't mean a Wacom tablet should be used for general computing.
