Sony Alpha Rumors has reported the release of the 3rd FF Sony NEX lens- Zeiss 24-70mm zoom:

 

(SR5) New Zeiss 24-70mm FE (Full Frame E-mount) lens coming too with the NEX-FF in October! | sonyalpharumors

 

The lens is to be announced or being available with the FF NEX camera in mid October.

That report can't say if this will be a new (slower and smaller?) lens or the current Alpha Zeiss 24-70 2.8 in an E mount. It should be pretty easy for Sony to make E mount versions of any of the current Alpha lenses should they see a market for them.

Hum... I don't surf frequently the Sonyrumors (only when is quoted in this forum...) but seems to me that they are playing hard on the Zeiss brand name... which indeed makes to think that some announcement on the FF side is preparing... they know that to be "accepted" in the FF world they need something prestigious on the lens' side.

I think the idea of a FF NEX camera is exciting.

 

However, is it not so that the Zeiss 24-70mm f 2,8 lens is known for its quite significant vignetting, - fully opened, - in wide-angle position, - used on alpha FF cameras?

 

This unattractive phenomenon will probably worsen even more if the lens is used on a FF NEX construction?

 

I neither believes this lens is weather sealed?

Sony Alpha Rumors is now reporting about messages that they have received. The third message which Andrea has reported as far as I am concerned is the most interesting- there are 2 FF E-mount cameras coming, one like the NEX-7, and one like the RX1.

 

Sony representatives now openly talk about the soon to be announced NEX-FF (and a hint on A-mount FF). | sonyalpharumors

Given Zeiss 24mm lens can work well on the SONY NEX FF, so will does LEICA 24mm M lens and above....

 

Hum... I am not so sure we can affirm this by assumption : we do not know yet how will be made the Sony NEX FF...

 

1) What will be its flange distance ? (I presume it cannot be like current APS Nex)

2) What will be the diameter of flange ? (I think it poses limitations on the design of telecentric wideangles)

3) Will they provide a sensor with microlenses ? (I suppose)

 

Surely points 1) and 2) will be engineered also in consideration of mechanical compatibility with current Sony/Zeiss FF lenses, which probably is a requirement, but maybe not a total and absolute one... they could evaluate that some limitations are acceptable.

 

If the flange distance would be not too different from M, so as the diameter, and if they have microlenses arranged not too differently from M, indeed there could be no reason for a Leica 24, or 21, would work well on this Nex-to-come.

 

I confess that most of my curiosity is about the styling they will adopt.... of course, it cannot resemble too much a Leica.... ;) still a very stylish and ergonomical design... I wondere also what would be the sense to have TWO mirrorless FF designs, one NEX-inspired, the other RX1-inspired, as speculated in the quoted Sonyrumors... :confused:

Sony is not going to make a third lens mount for interchangeable lenses. It will have the same mount and flange distance as all of the other Nex E mount cameras. Thus the flange distance will not limit lens design in any way as the barrel of the lens itself can be made longer or an adapter can be used to extend this to the correct length. Plus APS E mount lenses will work in cropped mode.

 

The size of the E mount is wide enough for a full frame chip so there is no problem there unless some special lens design needs a large rear element close to the sensor which has too big a diameter to fit through the opening. However every DSLR lens design will work along with many others.

 

It will have some kind of microlenses just as all sensors have. As you surely know, the primary concern on this forum is how well those microlenses and the sensor along with firmware (or compensation in post) will work with w/a M mount lenses. And none of those lenses have any physical restrictions that will keep them from mounting.

They covered this so don't be confused. According to the rumors...one would be a full featured camera with a built in EVF... expected to be like a somewhat larger version of the Nex 7 or Nex 6 design. This would have a bulged out grip and a tilting LCD.

 

The other one could be stripped down of the EVF, a fixed LCD, and perhaps not much of a grip to make it smaller.

 

This is no different than the strategy on the APS line in order to appeal to as many users as possible. I can see why some users would want both models if the size difference is significant.

 

I have no more knowledge than you about what Sony will actually introduce, but the two body approach makes sense to me and would show they are serious about mirrorless FF. Consider if the electronics, shutter, and firmware are the same or similar, it isn't very hard for Sony to produce two bodies. Didn't they introduce 3 SLT cameras at once?

 

Sony is going after GoPro too (although they have an uphill battle) so I think they want to have a significant presence in all aspects of cameras and video.

I think we are in agreement.

I like Sony's current strategy of distinguishing between cameras on the bases of features and interface design, rather than in image quality. To my knowledge (admittedly lacking), Sony features same or similar sensors across the product lines. The differences between serious amateur/pro and enthusiast/entry level cameras are feature set, ergonomics, and build quality. I hope they continue this strategy with the FF line as well. For some of us 10fps is of paramount concern, others need weather sealing, still others require tilting screens; some of don't care about build quality, control, or customizability, and some of us do. None of us should penalized (via inferior IQ) for our none IQ related preferences. That being said, I'm doubtful I'll be purchasing a Sony camera any time soon; Fuji with their X line and m4/3, especially Olympus, excite me a lot more. I'm in no danger of investing in them either. But if I had to start a second system, at the moment it'd be between the Fuji or m4/3. Nonetheless, I an tremendously excited to see some movement and rumblings in the FF arena. Sony not having a legacy system (they've all but given up on the Minolta), is in a real position to help cause a paradigm shift not in similar to Panasonic and Olympus when they started initially the 4/3 and currently the m4/3 systems. These are indeed exciting times to be a photographer.

-- -- -- --

Sony already tried going after GoPro but the first attempt wasn't fruitful. Well see what this second round brings. Having some inside knowledge of GoPro supply and fulfillment, and marketing strategy, the only comment I'll make is that at the moment GoPro is it's own worst enemy.

Unfortunately I don't have any Leica M wide angle or for that matter any Leica M lenses to check at this point. I have just ordered the 40mm lens on Thursday as my first M mount lens.

 

Also, for anyone interested and considering one of the E mount Sony cameras, this was mentioned over at Fred Miranda.com about a new adapter for the NEX cameras for the M mount lenses that will allow for information transfer between particularly the 6 digit coded M lenses and NEX cameras:

 

Phigment LM-NEX: Electronic Leica -> NEX Adapter - FM Forums

 

http://https://www.phigmenttech.ca/lmnex/

 

By the way, the new adapter had not been certified at this point for Europe, so I believe that it can only be sold at this point in North America and I am not sure where else.

 

Rich

 

 

Thank you so much Rich.

 

I just got the Phigmenttech adapter and tried it out with my coded Summilux-M ASPH. 35/1.4 and NEX-7.

It seems to work as advertised. It indeed transfers the focal length to the NEX-7 Exif.

One has to set the f-number both on the Leica lens and in the camera menu to get the actual value recorded in the Exif as well.

 

One also has to set AF/MF Select to Manual Focus MF in order to get automatic magnification when turning the focus ring of the Leica lens.

By pressing the wheel center in the back of the NEX-7 one can switch between 5.9x and 11.7x magnification.

After focus is achieved, half pressing the shutter button brings back the full view including focus peaking.

Very slick. I like it!

 

So far I have crashed the camera once, but that was before I had read the manual.

I don't know exactly what I did to cause that (most likely I took the lens with adapter off while the camera was still powered up).

Anyway, taking battery out and back in corrected the problem.

 

I will need to gain a lot of experience with a variety of coded and uncoded lenses (those can be set with a usb cable attached to a computer), before assessing the robustness and reliability of this adapter.

But so far it looks very promising. :)

 

Thanks again for pointing out this new adapter.

Hi Paul,

Welcome! Very interested in your new product as I'm sure other folks here would be as well. I'd love to hear more about it.

 

 

Hi Paul,

 

Welcome to the forum and thanks for your adapter.

My initial impression is that your adapter is the so far missing ingredient to really enjoy Leica lenses on NEX cameras.

It certainly has improved considerably the user interface.

Hr. Heinz,

 

Would you please share your experiences in using Leica R lenses on Nex 6 or 7?

 

Which is the shortest focal distance in your act, 21mm, 24mm, or 28mm?

 

In case 21mm works well, with the crop factor of 1.5 in Nex 7, 28mm lense may performs OK on the coming Nex FF.

 

Thanks and Regards,

 

 

Thomas Chen

Another nice ability of using your M mount lenses on mirrorless cameras including the NEX (and soon to be full frame), Fujifilm X, and M4/3 cameras is the ability to add a helicoid focusing tube/macro adapter. These allow your M lenses to focus substantially closer than they can on your Leica M body cameras (including the M240).

 

Hawk's Factory offers these in all 3 mounting systems that I mentioned above, Here are 2 links, one from one of the 2 USA agent the other from the actual source (the USA agent is selling the unit for less money):

 

Hawk's Factory Leica M L M to Sony NEX E Mount Macro Tube Helicoid V2 5 | eBay

 

Hawk's Factory Leica M L M to Sony NEX E Mount Macro Tube Helicoid V2 5 | eBay

 

Mine just arrived earlier this morning from the USA agent listed above. I purchased this in preparation for the release of the FF NEX camera and to try one or more M mount lenses on the camera (s) providing Sony allows me to do so at PhotoPlus in NYC October 24-26. I do not have a NEX camera at my disposal at this point, but the unit appears to be well made and finished, the helicoid is very smooth, and my just arrived Minolta CLE MC Rokkor-M 40mm f2.0 lens fits the unit well.

So, I updated the Phigmenttech adapter firmware to version 3 under Linux and shot a couple hundred images with the NEX-7 and Lux 35/1.4.

Everything worked fine so far.

 

When trying to copy the firmware under Mac OS X to the adapter I got the message: "The item “FIRMWARE.FW” can’t be copied because there isn’t enough free space." With Linux there was no such problem.

Karl,

 

Good. Mine is on its way. By the way, check my posting above yours.

Hi Thomas,

 

Many thanks. BTW, my first name is Karl-Heinz or in short K-H, either way is fine with me.

 

Now to your questions:

 

I am using mostly Leica R tele-lenses on my NEX-5N, NEX-7, and OM-D E-M5, soon also on OM-D E-M1,

for example APO-Telyt-R 280/4, Vario-Elmar-R 105-280/4.2, APO-Telyt-R 180/3.4, Vario-Elmar-R 80-200/4.

The former two lenses I use on tripod only, the latter two I can shoot also handheld pretty well.

 

The shortest focal length I have is the Vario-Elmarit-R ASPH 28-90/2.8-4.5.

Indeed, I am looking forward using that lens on an FF NEX.

 

In terms of a WA lens to use on the NEXs and OMD, my favorite lens is the WATE 16-18-21/4. No red edge to speak of. :)

That lens would also be very interesting to try out on an FF NEX. :D
