Sorry, but I keep my preorder, and

I welcome Sony A7r as my M9P's new friend.

I sell my NEX-6, and reuse the charger, both batteries, Nex-6 microphone, and E to M, R, and Nikon lenses adapters.

I think it's a good plan, and exactly what I had hoped for a few months.

My preordered Sony A7 LCD Protector already sent me, so it is too late to cancel A7r anyway.:o

My particular interest will be to use R lenses with a good adapter on and A7R. That, in turn, begs two questions for me:

 

first, obtaining a good adapter because some of the lenses are heavy (280 f4, 180 f2.8, 28-90) - Novoflex, Metabones, Fotodiox, or from SRB in Luton UK - so any thoughts will be most welcome;

 

secondly, many of the comments above centre on using M lenses especially wide angles - but I wonder how the 21-35 R lens will work as the rear element to sensor distance is much greater than with an M21 or WATE. And, importantly, how will the body be with the longer focal length R lenses???

 

Has anyone so far got experience of using R glass on the body...

 

 

R lenses are way out of proportion with the body, way too front heavy. They will perform fine, but are quite unwieldy in practical handheld use.

Hi Jaybob - have you actually tried R lenses on an A7R or are you simply surmising what they may be like?

 

Best wishes,

No A7 as of yet but longtime NEX user....135 2.8 on a louped NEX-5.

 

The images on the sensor (the end results) were stunning, but my experimentation didn't last but a few weeks. Your mileage may vary...

I think if you are not using an EVF and are composing on the LCD any camera is hard to hold for very long. An extended loup doesn't allow you to press the camera against your face either. The heavier it is the harder to hold. The Nex has a much smaller grip than the A7 thus it doesn't allow you to use all of your fingers to grasp the camera. So heavier lenses are hard to hold regardless of how large they are. The A7 works much better. Additionally there is an add on grip available for the A7 for those who want a larger grip or a vertical hand position.

Not yet, but you and I are on the same page. I recently picked up the Metabones R-E mount adapter. It is quite heavy I must say, but what impressed me for the $99 was that it includes a very nice tripod mount that is already shaped for QR use. It looks removable should one want to do that.

 

I'm interested in this adapter too. May I ask a question that is there a 1/4" thread socket in the tripod mount? Thanks.

IMO there is just one camera that is perfect to handhold for a long with a substantial lens and that is the R8/9 with DMR. And that is a bl***y heavy thing. ;)

 

All these lightweight small things are simply unbalanced and wobbly.

I disagree. I think the less weight in total, the better. I always support most of the weight of a long lens with my left hand under it. I feel a 100-400 Canon lens is a lot easier to hold on a 5D size body than on a 1D size body. Although having a vertical grip is nice. I stopped using 1Ds because they were too heavy for me to carry all day. I think an A7r would make it even easier to hold this combo. I just tested an old 400mm MF lens on my Nex 6. It is actually back heavy from where my left hand is placed on the focusing collar. So why would I want more weight back there? I can hold this very steady with that light Nex camera.

 

Besides, you can always add weight to a camera but you can't eliminate it. I once took apart a telephone that had a substantial heft to the handset.... there was a useless weight in it to give it "gravitas."

No, it has the QR plate on the bottom with two hex bolts holding it in place. You might be able to have someone tap a 1/4" hole into it.

As to the longer R lenses, we discussed that to some degree on Fredmiranda.com and the Suede who is quite knowledgeable indicated that he would expect no problems even when using the 1.4X and 2X Apo Extenders. The exception might be the 560mm f6.8 (and possibly the 400mm f6.8?) Telyt lenses where he thought that we may experience a small amount of vignetting of perhaps 1 to maybe 3mm of the frame.

 

Pretty certain it was someone who is active on this forum who was discussing the f/6.8 Telyts on the FM thread...

Hi Doug,

 

There is no question that you were most definitely involved in the conversation on FM. I am sorry that I did not include you in the reference. It was a discussion that you, the Suede, and I had in the thread. Please accept my apology for not including you in the reference.

A couple of points that I haven't seen discussed. The first is that I haven't seen real solid testing with just Leica glass so it is still hard to evaluate how they perform with either A7 or A7r. The second important point is that Leica does in camera correction for their lenses and I haven't seen anyone use the Sony app that will provide this ability to be tuned to the specific lens and to make corrections thus the comparisons are of an uncorrected image versus a corrected image. It is a no brainer to say that an uncorrected image will show vignetting and some color shift compared to a corrected one. Leica wouldn't have had to do the in camera processing if offset lenses on the sensor were enough to fix the close register problem. Sony allows one to do corrections for any lens whereas the Leica corrections are limited to Leica lenses.

 

Once we know the answer to those questions we can make a more informed decision.
