It's de-centered, for sure!

(off-topic: I'm trying to come to an understanding with the A7R, but it is the one digital camera I've used in the past 10 years which leaves me very cold...and I'm not sure why, yet. Full-disclosure: I've only used Leica M or adapted LTM lenses on it so far)

Why would those lenses scratch the sensor? It's not like they touch film on their original bodies.
I would expect shutter damage first.

I've been using all kinds of adapted lenses on my A7r and other than my errors haven't had any major issues, what leaves you cold?

I've used a J-12 on my M8 and M9 without problems-it's a 1943 Biogon in an early Russian Leica mount. It goes back pretty far!

What lens did they use? It almost looks like they dropped it onto the sensor while mounting.

Probably the smearing/corner performance with so many wide RF lenses....

It was cleaned with sandpaper.

I was just on your site earlier checking out some stuff. I might be renting from you soon

NEX adapters for Contax G allows focusing beyond infinity, so the rear portion of the lens portrudes much further back then on the G1/G2. On the APS-C cameras, it was the baffle around the sensor that took all the damage. Guess what happens with a FF sensor...

Siri, let the FE 55 make your day...almost too hot to handle.
Hotter than the 4th of July..

Thanks for the Dust Aid tip, Roger and Fred...saw the video, looks nice and easy.

The shutter is normally open with mirrorless cameras, so you'd damage the shutter only when releasing the shutter while the lens is in the way.

Yeah, that's what I'm reading and "seeing" at web size. I've only been using manual focus lenses for street shots with the A7R and it's getting tiresome.

That camera dented my wallet pretty badly and I am exercising restraint. The FE 55 is one *very* expensive standard prime.

That first bit was a joke.

I mentioned the bit about adapted lenses, to illustrate that irrespective of the lenses I'm using, the body is what's bugging me.

I'll try to be brief and pardon me for those that know well or have read about these things from before. People conclude at different rates
1. The menu system is really clunky
2. The ergonomics and button placement don't seem optimal, even considering the small body size.
3. The EVF is "nice" but is too small for my taste. My vision is changing, I'm getting a little older.
4. Niggling hardware or firmware issues, for instance the proximity sensor below the EVF, when you want to shoot from the waist with using the rear display. Or the screen which really never turns off. Or full-stop ISO increments...
5. The shutter that sounds/feels like a nano-pile of Jenga sticks collapsing in a quarter of a second. I don't understand how they could get to market without somebody saying "listen, we are producing a camera which is going to be coveted by enthusiasts, we really need to address features that such a user group will certainly want."
6. No external charger? It's a bit perplexing (and vexing!) for a $2,300 piece of equipment.

But, I won't give up on it, the camera does have a great sensor and lots of potential. I simply feel like I'm photographing with a camera system designed by systems/assembly engineers who never had a beer with anybody but their kin in the same department.

I like the Leica M9 variants in spite of their glaring faults. The EOS-M is a plucky little camera that can be a joy to use (certainly to carry) in the right situations. The A7R, it's in my bag as I go most everywhere, but mentally it's like I'm carrying around a camera which makes shooting feel a bit like a chore.

Restraint, restraint? I am trying too actually.

Seriously it is widely regarded as cheap for what you get, a real bargain. So far in front of the eq. ZEFs it is not in the same ballpark. I can't think of it as a standard prime lens, any more than a 21mm Distagon is a regular wide angle lens.

Even the cheap kit lens is getting good reviews from many users...see near the top:
http://www.getdpi.com/forum/sony/49391-fun-a7-7r-39.html

That one has three asph elements and an ED element. In a kit lens most people think is below them.

Poop. Damn you, stop instigating. :|

My wife is starting to recognize that not all cameras are black, nor a can be expected to have a reasonably similar profile, nor have an identical finish.

In short, gentlemen: she is becoming "aware".

Greg, you are in trouble!

P.S. my lens drawers have socks in them. ;.)

Jim, I was banished from one of the drawer units completely. I had it coming, that's for sure. Our place is tiny.

Thank goodness for "big tolerance".

That being said, I am going to sell a few choice bits in the next few weeks. Time to buy a (used) car and look for a nest.

Mmmm, choice bits.

Big tolerance. Big mind. Big love. It's all the same, and it's all good.

Ha! Looks like I'm not the only one to use that ruse. Lucky that my new Ricoh GR blends in so easily...

I'd "like" that twice, if I could.
