Mine finally arrived. Part of me kind of wishes I bought the r we'll see though still might get the r and sell off the a7. I only have a few lenses right now canon 50mm 1.4 ltm, canon 35 mm f2 ltm, cv15 mm, and g90

I've just bought an A7R and metabones adapter for all my existing ef lenses as well my rokkor and contax lenses which are leitaxed/Buchanan'd to EF mounts. I just tried fitting the contax 35 1.4 to the metabones and there seems to be a grinding issue with the EMF chip I have fitted to the leitax adapter. The connector pins of the metabones are crashing against the emf chip and have ground a pretty big groove into it. My A7R has not yet arrived to test if the chip works with the metabones or even if it is now damaged and not functioning. I tested with my ef mount rokkor 58 1.2 and there were no binding issues at all.
Any ideas if the emf chip is even usable with the A7R/Metabones combo or should I just remove them and use the lenses without exif?
If you can input the set aperture on the A7 in manual mode for exif purposes I might just remove the chips altogether.

With no electrical connection you will get only value 0 saved to EXIF-field "FNumber". I'm shooting either aperture series (full apertures starting from largest aperture) OR I shoot on special sequence, e.g. C/Y 1.4/50 there is no point shooting f/1.4 so I usually shoot f/2, f/2.8, f/4.0... When I import photos to computer I use exiftool to save actually used aperture (and some other EXIF info like max aperture and focal length).

Thanks Samuli, very helpful. I think I may end up buying cheaper mounts and use the lenses 'natively'. I'm having a separate issue with my TSE 24 II, and if I end up selling that I'll probably get rid of the metabones and give up on canon. I was hoping to just use the one adapter and keep all my lenses with the same mount.
Do you know if keeping the chips on the adapters will cause any issues or are they just ignored?

I have the opposite strategy, adapter for every lens I take to my backbag. Thou this limits me to use only one ZE-lens, so maybe I get another metabones at some point.

Sorry, don't know - didn't try as I didn't want to add more flexible surfaces between lens and camera, those can cause lens to tilt or being too close/too far from the sensor. Actually I have glued some of my adapters to lenses for more robust connection (e.g. my FD 85L has very worn out lens mount and works 1000000x better with glued adapter).

Thanks again. Hopefully the leitax and Buchanan mounts which are screwed on are tight enough to not produce tilting. We will see when my camera arrives tomorrow!

My Leica 180APO is with Leitax (EF) mount, and I'm using it with non-electronic EF-FE-adapter. It works well that way, specially as I connect tripod to tripod collar, and adapter & A7 don't weight anything.

I've got the Ciecio7 adapter. Like the Novoflex, it's made from a solid billet of aluminum. It looks a little funky, but it's a perfect fit, and only $50 or so.
I've had a Ciecio7 FD to m4/3 adapter for three years and it's been utterly solid and dependable.
i bought a cheap Pixco FD adapter when I got my A7 in early December as I wasn't entirely sure I was going to stick with E mount. I can't say I've noticed any issues with alignment, but the Open/Lock ring has been a right pain - constantly returning to Open position. Today it gave up the ghost entirely, and it now refuses to stay locked, so I can only shoot with the lens wide open.
I ordered a Ciecio7 FD-E adapter this afternoon.
The only foreseeable problem is that my company's office in Warsaw told us a couple of days ago that Poland is on national holidays from the 1st May to the 5th...

Would there be a benefit of turning off the Long Exposure Noise Reduction (LENR) and handling the noise in off-camera photo editing software? Or is the A7(r) pretty handy at noise reduction with long exposure times?

the benefit would be time saving, there would certainly be an iq hit for not doing black frame subtraction.

I don't think it's something you can do in post very effectively without a dark frame. The dark frame should be taken around the same time because camera heat comes into play. The alternative to in-camera dark frame subtraction is even more inconvenient: Take a second exposure with the cap on and reduce noise in post.
I always leave long exposure noise reduction on.

Hello,
I was considering getting the 55 FE for my A7r... but after testing it personnally and observing a magenta cast wide open (camera auto-corrections disabled)... I'm very disappointed. I knew these casts showed up on the 35mm FE, but on the 55, not.
Not my pictures, but these show what I'm talking about:
Sorry if it has been reported here already, I've not read all 190 pages.
I hope this gets solved with the 16-35, but the fact that the wider a lens is, the (usually, depending on lens design) shorter the rear element to sensor distance is, does not make me particularly optimistic.

There must be some thick filter used on those shots, or some kind of weird post processing, the FE 55 does not show that kind of magenta cast.

I have to disagree, here is one shot I took outside my camera shop, full aperture:
No filter, no nothing, just the RAW SOOC in lightroom.

If one turns all auto corrections off in the camera - vignetting and so forth - perhaps the FE 55 does show the issue...or perhaps this is a quality control issue of some sort?

Did you even check the photos you linked from flickr, they have about 50% magenta cast in corners, that looks like putting a rangefinder wide on A7. I've been shooting now daily a month with A7 + 55 1.8 with lots of sky in the photos and never encountered anything like that.
