You could buy the ZE-version of the 2/28 and the Metabones Mk III Smart Adapter, and have the best of both worlds (MF with electronic aperture control and EXIF).

p.71 #2 · A7/A7r - performance with WA RF lenses


Albi86, I believe the rumour is that Sony will introduce 2 new full frame cameras, not 2 new "A7" cameras. If there is a pool, my bet is the 2 new full frame cameras will be a 36MP AA filterless RX2r and an A99r or whatever they choose to call it.

Introducing a new A7 class camera so soon after these two doesn't seem necessary for Zeiss to do well with them.

Hi guys, like you I'm also interested in the Sony a7 and RF lenses combo. Seems like some Voigtländer and Leica APO lenses could really be life-long investments, with modern Zeiss lenses filling the gaps and the eventual need for AF.

However, at the moment I'm waiting because I don't think this generation of cameras are really good for that. The a7r seems to be better in terms of microlenses design, but consider that the very high resolution is going to exharcebate every such imperfection. Not to mention that even with focus peaking, obtaining critical focus wide-open is not going to

Well, you can always wait, and you'll likely be rewarded for it. I agree that 36MP may seem over the top unless you print really large, but having this resolution for cropping and/or down-sampling is definitely a plus in my book. Personally, I would not hedge my bets on any camera manufacturer other than Leica releasing a future camera model that is better optimized for RF lenses than what is currently available on the market. I have a feeling my (future) A7R will remain in my stable for a long time...

Edit: the only thing that would definitely make me consider upgrading to a future model is in-body IS. That's the only feature I truly miss on the A7/R.

Still would miss the aperture ring.

True, but you don't have to use stop-down metering and you can use shutter priority - not a bad thing for nature photography, IMO. Plus the ZE focuses considerably closer than the C/Y, IIRC.

I doubt very much that the IBIS E-mount FF camera could be made the size of the A7/A7r at present and even quite possibly in the future.

I fully agree. I think the current form-factor is close to perfect, and I prefer not having IS over a larger body. I really like the size of my NEXes, and I think the slightly larger size of the A7/R may feel even better in my hands. And as a side note, I also truly like the video features (VU meters, peaking, zebra, jack pack with XLR audio) of the A7/R. They definitely don't look like they were an afterthought, and will add value to the camera for me.

Of course I might stand corrected in the next few months, when people will be actually be trying out the various combinations.

My guess is that while the a7r will offer better IQ in absolute terms, the number of keepers in non-controlled scenarios will be dramatically lower than expected - for a number of reasons. And actually, RF lenses >50mm and adapted DSLR lenses might work more smoothly on the a7 than the a7r.

Also, considering that the new native Zeiss primes came without IS, I would imagine that a body with IBIS is definitely in the plan. You have to remember that if Sony got us drunk at the first round, it would be very hard for them to sell a second. For me, personally, a big deal breaker of the a7r is the flash sync limited at 1/160s.

I'd prefer it was smaller yet, but console myself with the semi-weather proofing and built in EVF.

If the cameras were much smaller you would have difficulty in using and balancing the cameras with larger and heavier interchangeable lenses.

Ever since I invested in the NEX-7, my cameras have lived on a tripod for just about all serious shooting. I would really like to see that change with a body featuring IBIS, but like Rich, I honestly don't see it happening any time soon. Stabilizing a sensor of this size requires space, which in turn would make the camera larger, thus negating much of its appeal. Perhaps it would be possible to incorporate IBIS without making the camera much larger if the rear display were firmly built into the body, but I don't think Sony would do that.

Of course, the D21/2.8 is also a winner.

For me, there's no way I'd want IBIS over a swivel LCD - I used the second much more often than the first, and the swivel LCD was one reason I even considered the A7 for purchase (now on pre order)....the lack of one is why I don't own a Fuji XE2 right now

I use the nex5n with the 70400g all the time. I use it with contax 100-300 all the time. I use it with with the nikon 180ais ed all the time.

Is it a problem? No. Do I sometimes wish the body was bigger? Never.

I think it's a familiarity issue.

Google image the CLE: you will see it with every sort of monster rf lens, like the canon .95. They knew then: it's nicer when the body is compact like the original Leica

As to tripod? Never use one in the field. If I'm out really long I go up to 1200 shutter or so.

I'm not so sure, have the lenses announced have OSS. Both zooms, the 28-70 and the 24-70 have stabilization....the primes don't. The primes were probably designed with image quality, size, and speed...in that order (or there abouts.) The zooms were larger and slower (as usual), but given they were going to be larger anyway so adding OSS probably didn't add much to the relative size. It also helps make up for their speed.

Well here are some photos of my Fujifilm X-E1 system before I purchased the Fujifilm 14mm f2.8 lens and yes I had other MF Leica R lenses to use with the camera as well.

Nice lineup, Rich. How do you like the RRS grip? I have the rail, but held off on the grip and L, because I want to keep it small. I often shoot it handheld at events with two other cameras, X100s and 6D. The grip would make it easier to grab teh camera & lift to my eye, but it seems OK without.

Rich, what has your experience with the Novoflex ASTAT-NEX been when using heavy lenses as shown in your images? Is it rigid enough to prevent shake caused by the shutter? I wish the A7R had an electronic first curtain...
