    35mm RF lenses on A7r?

    As I piece together a set of lenses for my A7r, Im looking for a small(ish), light, semi-fast 35mm. I already have the CV 35mm f1.2, but Im thinking something small for when I want to travel light.

    Considering the Zeiss Biogon f2 ZM, 35mm Summicron ASPH, 4th Version Summicron, maybe even CV 40mm f1.4?

    Anyone using these, or have any other suggestions? Anecdotal reports seem to be all over the place, and inconsistent.

    My primary consideration is sharpness/resolution, and lack of edge smearing. Vignetting and higher or lower contrast, I can deal with.

    Any thoughts or suggestions?

    Re: 35mm RF lenses on A7r?

    Why not the Sonnar T* FE 35mm F2.8 ZA native lens? It's sharp, "semi-fast", and very small. Plus, it's designed for the A7/A7R and doesn't need to be adapted.

    The Biogon f2 is truly awful on the A7r.

    I have the Zeiss 35/2. Purple vignetting and smearing on my copy. I am selling it. Might be OK on a different camera as they are so inconsistent.

    So is the C Biogon 2.8/35 ZM - likely worse than the 2/35 ZM due to it's strongly protruding rear element.

    The Summicron 35 asph is not acceptable it has it all, smearing, color cast, vignetting. I`d choose the excellent FE 35mm over the ones mentioned.

    Repeating myself, IMHO, the best choice at that focal length is the Sonnar T* FE 35mm F2.8 ZA native lens. It's sharp, "semi-fast", very small, and at USD 798 is a bargain compared to alternatives.

    I think you're right. If the native 35 is anywhere near as good as the 55 it'll be worth the money, if we could find one here in the UK.

    Agreed, and I may end up there--but my thought is to at least try to find a viable alternative-- with the intent to build a lens array that is NOT tethered to any particular camera brand/mount-- assuming that in the future, developments may allow switching or adding bodies, without the upheaval and expense of switching systems...

    I'm with you on this one. I agree with Joe that the FE35 looks fantastic, but I'm sticking with my existing SLR 35s for the time being. I've used both the Elmarit-R 2.8/35 E55 and the ZF.2 2/35 with the A7R, and they both work well. The former is very compact and shows relatively complex field curvature which is easily overcome by stopping down, while the latter is a bit larger and shows some CA wide open that improves rapidly when stopping down.

    If you don't mind the size, the Sigma 1.8/35 in Nikon-mount might be worth looking at, too (Nikon mount because it gives you most flexibility regarding mounting on different systems)

    Re: 35mm RF lenses on A7r?

    I have the A7r and two 35s: FE 35 2.8 and the CV 35 1.2. I think the CV is fully competitive with the FE. The CV us much heavier, so for hiking/landscapes, the FE goes in the bag. At infinity, the FE is better in zones B and C till F5.6, but at 5.6 and smaller, the FE loses its advantage in the corners. Before F5.6, the CV is equal or better in sharpness/contrast in the center and most of the frame. The CV is weighty, but the solidity is welcome to me for hand holding stability and it is more than two stops faster.....

    Re: 35mm RF lenses on A7r?

    I'm using an older Leica 35mm f/2 Summicron Pre-ASPH and loving it. My Contax Zeiss 35mm f/1.4 also looks like a winner, but more testing needed with it. The 'Cron is so amazing, I have a hard time taking it off.

    Re: 35mm RF lenses on A7r?

    I think the 35 Sonnar FE is the only option. It has the added bonus of weighing only 120g.

    I was not planning on switching into the A7 system, but I am increasingly of the opinion that thinning out Leica kit to pay for a switch (and having money left over) is the best bet. I'm priced out of Leica's future anyway, so why retain lenses for a system whose manufacturer cannot make a body that uses the lenses for under $7K? At least I have a future with Sony and, even though the M240 or MM may equal or even outperform the A7R in some areas, even if I only buy into alternate sony generations, I will be able to buy into Sony development for the next decade for the price of one Leica DRF body now. Switching systems will free up cash, even after the switch.

    Absolute optical perfection is not necessary for most people most of the time. Heck, it was not even present in all of the Saint Ansels images, some of which were not enlarged heavily due to corner softness, or wind vibration. I was not surprised to see the Leica 50 APO Summicron, but did feel it confirmed that Leica was heading in the wrong direction (still) by concentrating on exorbitantly priced perfection rather than getting cameras and lenses into the hands of talented photographers. In the past, I think they were more practical and less elitist, but the financial success of their boutique approach cannot be argued with. The company has to survive.

    Here enters the A7/R. It lacks in some areas, but is dynamite everywhere else, and for a fraction of the cost of the M240. Its the 90% solution and the one I have been waiting for, personally. I could not care less if the 35 FE Sonnar is not quite as sharp on the edge of the frame as a 35mm Cron asph/Summarit/FLE on a M240 under close inspection, because its gonna be close enough not to really matter. The total buy in for that pair is (in the UK) 2329 (Sony A7R and 35 FE) and 6300 (Leica M and Summarit). Nuff said.

    Sony is going to rake in the cash from these new Alphas and will reinforce success with more R&D and great new releases. This is just the beginning. If rumour is correct and Zeiss produce an equivalent of the ZM line for the FE system, we can expect astounding edge performance, nice manual focus and far lower cost than leica glass. Even selling old Leica lenses will probably more than pay for buying in new. The only areas I see the alphas being a little weak is in street photography, with the quick release of the Leicas and the OVF.

    Lots of waffle, but thought Id share where my thoughts have been going.

    Re: 35mm RF lenses on A7r?

    I agree that the FE 35, though I do not have it, is likely the best option for the A7r. But a good SLR lens will probably do fine.

    After putzing around with all sorts of M lenses, I decided it made sense to skip most and go with SLR lenses. I have tried both the lowly (less than $300) Contax 35/2.8 Distagon and a somewhat more expensive Elmarit-R and they both seem very good on the A7r.

    Some M lenses I tried are acceptable for general use if stopped down. Even a 90 Summicron has fairly poor corners on the A7r, in my experience. For me, trying to assemble an A7(r) M-compatible kit was a fool's game; I like the camera and will try to play to its strengths, either with native lenses or SLR lenses. This is the same conclusion I came to with the Fuji X-Pro, skip the dream of full M compatibility and go with the camera's strengths.

    I was interested in your statement about the 90 cron. I have had good results with this lens on the A7r (even wide open) and I am fussy. For example, I have yet to find a 35 that I like, including the FE35.

    If there are issues with the 90 cron, I should be careful about recommending it to others. Can you give more details? Is yours an early version or the asph?

    Agreed..... I have the 90 Apo Summicron Asph M and find it to be outstanding on the A7r. I am also very fussy and know a good lens when I see one.....

    Re: 35mm RF lenses on A7r?

    I am not saying there is anything wrong with the lens, of course, just the combo with the A7r.

    Mine is pre-Asph, and the corners are simply not up to par, IMO - particularly wide open. Maybe I expect too much, but I think I should get good sharp results with a 90mm lens even in the corners. It always seemed to perform acceptably with my M9, but I have not done a comparison since I no longer have the M9. Maybe an Asph will perform better - I won't be investigating that first hand, however.

    And Cunim - are you saying that you have found no 35mm SLR lenses that are acceptable, or are you just speaking of M or the FE lenses?

    Re: 35mm RF lenses on A7r?

    Lloyd Chambers has a new write up comparing the Sony Zeiss 35mm FE lens with the Leica 35mm f/1.4 Summilux-M ASPH and the Zeiss ZM 35mm f/2 Biogon, all on the A7R. It's a subscription only site, but the price is a pittance for anyone thinking of buying a Leica or Zeiss lens for an A7 or A7R.

    Sorry, I have only tried the 35FE and ZM 35/2. The 35FE is actually pretty good but the corners smear a bit and I am sensitive to that. You might not be. I shoot longer almost all the time so it doesn't matter enough for me to get in adapters and try out SLR lenses.

    +1 for the 90mm Apo-Summicron-M ASPH. I've found mine to be sharp corner-to-corner with the A7R:



    Regarding lenses for the A7R, I find it somewhat masochistic to use a big honkin' DSLR lens on the compact A7/A7R cameras. Especially when there's a decent 36MP 35mm full-frame DSLR camera alternative - the D800E - or decent small lightweight lens alternatives at the desired focal length(s). The incredibly small Sony A7/A7R, IMHO, demands lenses that complement its size and weight. My recommendation of the Sonnar T* FE 35mm F2.8 ZA native lens is consistent with that philosophy and reinforced by Lloyd Chambers' findings in his recent article comparing the Leica 35mm Summilux-M, Zeiss ZM 35mm f/2 and the Sony/Zeiss 35mm f/2.8 native lens on the A7R. Bottom line: the Sony/Zeiss 35mm native lens more than held its own against its pricier breathren.

    And to be completely honest, I'll be trying some DSLR lens alternatives for the longer focal lengths (>135mm) until Sony introduces native lens alternatives in the new mount.

    Re: 35mm RF lenses on A7r?

    I agree with Joe: I purchased the A7R to compliment the D800E. I wanted it for the small profile and amazing image quality and I intend to use it with the small FE ZA lenses and perhaps some other old jewels such as the Olympus OM lenses. Check out the size of the diminutive 35mm 2.8 and 24mm f2.8 OM lenses!
    Just a thought from an old Canon FD, Olympus OM and Contax RTS II user.

    I am quite sensitive to it - that is why I am basically going with SLR lenses.

    I hear you - different things irritate different people.

    I find it masochistic to use most of my M lenses on the A7r - the bad edges and corners are torturous. One that does work just fine is the Noctilux F1 - the sensor weaknesses are overcome by the lens flaws so all is good! I find that a C/Y 35 2.8 is a pleasure to use on the A7R, and the Elmarit-R 35 is bigger and heavier, but really no more unwieldy than my Summicron-M, it is shorter though squatter (that's with the thin M-Nex and Honking R-Nex adapters). And of course OM lenses are very tiny and even with adapters I have not used one that seems big or heavy with the A7r.

    I never considered a Nikon digital, don't think I will now, and it definitely won't work with a Noctilux (unless DigiLloyd knows a way to do it. )

    Understood. No argument here.

    Having come from the Nikon digital world, and having owned a D800E and just about every Nikon lens from 14mm to 600mm, I've given up weight and volume for convenience, ease of use, and less back pain. My reason for mentioning the D800E is that it has, for all practical purposes, the same 36MP Sony sensor as the A7R. While some would argue that the ISO performance of the Sony A7R sensor is one to two stops better than that of the D800E, I haven't seen any empirical results that prove that. I'd bet (and have) that it's more a difference in the marketing approaches of Sony and Nikon.

    Having chosen the compact mirrorless kit to lighten my load, my quest is for lenses that complement the size and weight of the camera body, like the native 35mm and 55mm. And fortunately, I have a kit of Leica M lenses that I can play with, while I wait for the E-mount lineup to be filled in by Sony/Zeiss and other manufacturers. Fun times.

My recommendation of the Sonnar T* FE 35mm F2.8 ZA native lens is consistent with that philosophy and reinforced by Lloyd Chambers' findings in his recent article comparing the Leica 35mm Summilux-M, Zeiss ZM 35mm f/2 and the Sony/Zeiss 35mm f/2.8 native lens on the A7R. Bottom line: the Sony/Zeiss 35mm native lens more than held its own against its pricier breathren.

    And to be completely honest, I'll be trying some DSLR lens alternatives for the longer focal lengths (>135mm) until Sony introduces native lens alternatives in the new mount.

    Re: 35mm RF lenses on A7r?

    A very enjoyable discussion! For me, it boils down to this: the A7/R are an excellent platform that suits many people's needs and wishes. If you have SLR or RF lenses that work really well, there's little reason to invest in something new. If you don't, then Sony's FE offerings look like a terrific choice. Personally, I'm happy to stick with my SLR lenses while I wait for Zeiss to show their hand with native FE glass. The FE 4/24-70 is the only AF lens I'm interested in (if turns out to be a winner)...

    Re: 35mm RF lenses on A7r?

    Back to OP's question about 35mm:

    I did some pixel-peeping and found that 40mm Summicron and 35 pre-aspherical Summilux were best at larger apertures (from widest to f4). Neither discolors nor smears in the corners. I'm using the 40 Cron as my basic A7 lens.

    35mm Summilux FLE flunked out, with corner discoloration and smearing still prominent at f4.

    35mm Summicron v. 4 fared poorly at f2 and f2.8, though better than Lux FLE. It looked tolerable at f4.

    I can't join the bandwagon for 35 Nokton 1.2 on A7/r. As above: "The incredibly small Sony A7/A7R, IMHO, demands lenses that complement its size and weight." The bulk of the 1.2 Nokton defeats the purpose of a small and light camera. And with higher ISOs available on A7/r, one shouldn't need f1.2, where it's hard to pin down focus. Finally, CA is prominent at its large apertures.

    I haven't seen any tests of 1.4 Nokton, which is supposed to be a pretty close approximation of the pre-asph Lux. If it works as well as the Lux it would be both light and a bargain. Its focus shift problems would vanish when focusing manually at shooting aperture.

    Absolutely, the 35 Nokton is not an everyday lens, but it is a handy second 35mm. I believe mine to be the best value (by a country mile) Leica M mount lens I have and it produces quite exquisite portraits and low light images. I am about to buy the 35 FE Sonnar as the 'main lens' for all the reasons I mentioned earlier: sharp, light, great all rounder.

    Unlike with film, where you can use the same film stock with any camera brand, the size and design differences of the sensors in various digital cameras practically dictates that you'll want to reevaluate your lens lineup whenever you switch cameras, so I wouldn't worry too much about finding a lens that will last you forever, especially at the price of the FE 35.

    Re: 35mm RF lenses on A7r?

    Mr. Joe Colson probably one of the nicest guys whom I have never met in person is absolutely 100% correct on his spot on analysis.
    Choose your poison, A7, or A7r, both fantastic cameras IMHO, though again IMHO, attaching a DSLR lens with an adaptor and all of the sudden the Sony losses it's main appeal size, form and function. Also for those going through the exercise trying to diminish the shutter vibrating issues, using complicated RRS rails, and foots and whatever else it take to get a sharp image, I give you guys a lot of credit, but for me to go through all this again really defeats the whole purpose of the A7r.

    I wanted my A7 kit to be as small and light as possible so I ended up with the FE35, I already owned a Zeiss 50/2ZM, which works great on my A7 at F5.6 which is all I need and a Zeiss 85/4ZM ok not a very fast lens but very small and light and at F5.6-8 also performs great.
    The only DSLR lens I am testing is my converted Contax Zeiss 135mm F2.8 Sonar lens with a Leitax Sony A mount and using Sony's LAEA3 adaptor. Initial results are very promising.

    Now if I can only find something worth shooting here in Park City, Utah I would be really happy

    Re: 35mm RF lenses on A7r?

    Anyone tried or had success with a Summaron 35/2.8 or Summaron 35/3.5 on the a7R?

    Re: 35mm RF lenses on A7r?

    From what I have seen most if not all 35mm RF lenses have some kind of issue though depending on subject matter these issues maybe non issues to some. Only you can decide if you can live with these issues. I still lime the FE35, I think its a very good lens

    Sorry but can't agree – see my post above re: 35/40 M lenses that function quite well even at largest apertures.

    Re: 35mm RF lenses on A7r?

    My comment was more in line with current RF lenses. I am sure there are some older retro design that work like the WATE. Yet at the end of the day, native FE lenses will always work best. I would sell my 50/2 ZM and my 85ZM yet for what I shoot they work great and don't interfere with form and function of the A7

    Yeah, from what I've seen, some of the older lenses and designs like the Leica 35/1.4 pre asph, 35/2 IV, 40/2, Contax G35 and Nokton 35/1.4 don't have much in the way of issues attributed to the A7/R's sensor. However, these lenses aren't particularly high performance across the frame on any camera in the first place, compared to more modern designs like the Leica ASPHs and FE 35, so it just depends on what one wants.

    The Nokton 35/1.4 seems to have a pretty intense Zone B dip, but it would be a great people or "vibe" lens, outside of the excessive purple fringing that seems to plague a lot of the fast Voigtlander lenses.

    Oh, those poor old low-performance, resolution-challenged lenses (that some of us prefer):
    At high magnification you can read the label on his peanut butter jar and see how much of it he's eaten.
