    Re: Sigma 30mm f2.8 DN

    wow, what a lovely lens vivek. How long have Sigma E mount lens been available?

    Still thinking of getting a VC 35mm f1.2 with helicoid adapter, but looking at the Sigma 30mm f2.8 DN seems like a good choice with AF capability sacrificing just over 2 stops of light.

    Choices choices, which to go for in your opinion?

    The Sigma E 19/2.8 is now in stock at 47th Street photo (and can be purchased through Amazon). At $219, I just plopped down for one - I'll report on the lens performance in about a week once I've had a chance to play with it.

    I bought one yesterday overseas at DigitalRev for $190 including shipping. It appears B&H also has them in stock for $199.

The adapters should be here by the weekend so I can test my idea.

    However, back before I got back into Leicas I used to frequently carry just a meterless Nikon F2 with a 45/2.8GN. I never felt constrained with using just this single lens for casual walking around; this is why I ordered a Sigma 30.
    We're on the same page. I ordered the Sigma 3/2.8 for the same reason -- even though its 45mm EFoV doesn't fit my 35/75 ideal, if I'm constrained to using a single lens then 40-45mm on a full frame camera has always felt just right.

    I think purchasing the OM and F adapters was a really smart choice. I was very happy with a series of pictures made this last New Year's Eve using a Rokkor 24/2.8 and a Hexanon 50/1.4 on my NEX cameras (because I wasn't sure how the tired and emotional* crowd might respond to being photographed).

    * "tired and emotional" is a euphemism for "drunk" that Australian journalists borrowed from their British counterparts.

    In my opinion (for what it's worth), I think that if you have set your heart on the VC 35/1.2 then anything else will leave you with a sense of lacking. I think that the Sigma 30mm is a great little lens and pretty handy for general use but as I suspect, you are an available light shooter, the 2.8 aperture may be a bit of an issue for you.

    If budget permits, perhaps both lenses? I can see myself, for example, being tempted to get both the CZ 24/1.8 and the Sigma 30/2.8 even though I already have a Contax G 35/2 Zeiss. I think that there are lenses for different occasions and where money isn't an issue, that can mean you "can have your cake and eat it"!

    If I had to choose just one lens, I would get the one that I couldn't live without, so which one is that for you?

    Like Alphaman says, it is your call.

    FWIW, I do not have the CV35/1.2 and have no clue how that works on the 7.

    I do have the Olympus pen F 40/1.4 (as well as the 42/1.2 and the four different 38mm lenses) and that is just fabulous! One of the 38/2.8 lenses is a pancake (a true pancake).

    Among the E primes, 30/2.8 DN, 30/3.5 macro (only for that- macro), 24/1.8, 50/1.8. All work well for me.

    The rumored 30-35mm "fast" prime is most likely an f/1.8 lens just like the other two fast primes. I do not think Sony's current CDAF can handle faster lenses.

    That's exactly what I've just done. The G 35 has been my go to lens, so I sold a bunch of rangefinder lenses and bought a Sigma 19 and 30, as well as the Sony 24/1.8 and 50/1.8, to see how I like the option of AF. I figure that $1700 for a pretty well covered, 4 prime setup isn't too bad, when you compare it with the cost of rangefinder lenses.

    BTW, from what I've seen, the CV 35/1.2 is about the best 35 out there for the Nex-7, if you can deal with the size and weight (which I can't.)

    Here's a quick one from in front of my office. It actually stopped raining for 1/2 an hour!

    Nex 7; Sigma 30mm f/2.8; 1/4000s @ f/2.8; -1/3 EV; ISO 100


    And, one with the Sigma 19mm at the camera store.

    Nex 7; Sigma 19mm f/2.8; 1/100s @ f/4; -1/3 EV; ISO 1600

    Looking good , Matt.

    The 19/2.8 DN has been available here for the same price as the 30/2.8 DN. I am still not sure about it. The shop I bought the 30mm from has sold out their stock!

    Great shots of the mission, Uwe. That lens looks like a great performer.

    By the way - you labled the folder as an f1.8 lens on your site, but it's actually an f2.8 lens, correct?

    Uwe, it's great fun to compare the gallery images you've posted with the NEX-7 and Sigma 30/2.8 against the similar ones you did with the D800 and 105!

    Re: Sigma 30mm f2.8 DN

    Anyone noticed that when you turn the lens over (not mounted) or tilt the camera when mounted that the internal mechanism in the lens moves around? Mine arrived today. Seems to focus fine but the internal movement is a bit disconcerting.

    This is totally normal
    I hope this will be no problem over a longer period of time.

    I mentioned this in the first post here. Normal as Ingo says. I would still transport it in the heavily padded tiny bag that Sigma supplies with this lens.

    Looks like normal. But why does it happen and why does Sigma find this normal.

    Good question Uwe but no aswer in sight
    I never heard of something like that before on other lenses but I read it has something to do with the focusing mechanism...

    Re: Sigma 30mm f2.8 DN

    I've already posted these elsewhere, but these are the first two I've processed from the 30/2.8.

    This lens *very* much feels like my beloved Nikkor 45/2.8GN, and it goes beyond the focal length. Has anyone seen an optical formula for the 30/2.8? Is it a Tessar like the GN?

    Re: Sigma 30mm f2.8 DN

    I have the GN Nikkor 45/2.8, a 30/3.5 Schneider Xenagon and real CZJ Tessar 3cm f/2.8 lens. All Tessar or clones. Tessars are 4 element 3 group lenses.

    The Sigma 30/2.8 DN is VERY different (Specs. see: 30mm F2.8 EX DN HSM - SIGMA CORPORATION ).

    Key difference between the Tessars and the Sigma is the telecentricity- ie. wide open or closed down there is little difference in the light fall off as well as with the change in magnification.

    Also, the Sigma 30mm is significantly sharper than the GN Nikkor.

    Re: Sigma 30mm f2.8 DN



    My Sigma 30/2.8 sits here, as does the CV 35/1.7, 35/2.5 and the MS Perar 35/3.5... while the NEX 7 travels Australia-ward.

    I bought the Sigma for $199 (B&H) by preordering. This lens is looking like a winner.

    I will be very interested to see which of these lenses is the sharpest; I have already satisfied myself that the Perar is the least sharp, but it does render pleasingly, and it is unbelievably small.

    . . . Yes, except China - we bought a camera for Sim in January to deliver about 300 miles away in China - it was incredibly complicated and took nearly 3 weeks!

    Glad you got a good copy of the Perar, Kit. Cool lens. I have a feeling that you'll be surprised how sharp the Sigma is.

    You're right - that ain't no Tessar!

    I'm either spoiled with a good copy of the GN or I just haven't subjected it to critical enough use. This lens does great on Tri-X at 8x10 but may be quite different on a high megapixel digital camera. I'll have to try it on my D300 and NEX-7 to see!

    Re: Sigma 30mm f2.8 DN

    There are no bad copies of GN Nikkors (I have had several over the years). The angle of coverage on an F2 with that is exactly the same as the Sigma 30 DN on the NEX-7 (same deal with the other 30mm Tessars I mentioned). That could be the cause.

    My current GN is considerably better than my first that I bought in '75. Yes, I do like the FOV of a 45 on full frame which I'm sure is part of my I like my new Sigma. To me, the images also have a similar "feel" (beyond the FOV) despite the different optical formulas.

    Re: Sigma 30mm f2.8 DN

    I have taken Douglas's approach.
    Sigmarit 19 and 30mm for 400.00 a total no brainier,
    Now if I can find some who has stock on the Sony 24 and 50 emount,
    I will be set. I also have a Contax 90mm G with a fotodiox mount works great.

    Re: Sigma 30mm f2.8 DN

    A question for other owners of this lens:

    I've noticed my NEX-7 takes quite a bit longer to power up or wake from sleep when the Sigma is mounted as compared to the kit lens. It's not a big deal for me because I tend to not let the camera sleep when I'm actively shooting, but it could be an issue for some. I have a question in to Sigma USA's technical people about this.

    Could others chime in with their experience?

    Re: Sigma 30mm f2.8 DN

    Yes.

    The NEX-C3 with this lens is even slower. The C3 is already slow to "wake up".

    FWIW, I only have SanDisk SD cards. This behavior might be different (for the better) with the Sony cards which are reported to be more efficient.

    Jumping on the Sigma train as well. Ordered the 30mm from B&H - can't believe I forgot about DigitalRev, I could be using it now!

    I'm going to keep the Zeiss on my 7 and use the Sigma on a "beater" 3 for my go everywhere, don't care what happens to my gear, camera. At $400 for the body lens combo, I think this might represent one of the best performance/value combinations out there.

    Re: Sigma 30mm f2.8 DN

    NEX-C3 and a few tiny manual focus lenses (in place of the 30/2.8 DN) make the "go anywhere" package for me. NEX-C3 + C-V 15/4.5 + W-Nikkor-C 2.5/4 + Olympus pen F 38/2.8. All the lenses are far more expensive than the C3 but are tiny and find a place in small pockets.

    The Sigma 30/2.8 DN really shines on the NEX-7. I would think it would do very well on the 3 & 5 as well.

    FWIW, there is a small price drop of the Sigma 30/2.8 DN in the EU! It is about 12 Euros cheaper than what I paid for (while the Sony lenses go up in their price).

    Re: Sigma 30mm f2.8 DN

    Just ordered the two Sigma's 19 and 30mm. for € 348 shipping included.
    My first AF lenses for the NEX-7.
    I do miss AF sometimes in streetphoto situations.

    Question; is it possible to use the Panorama setting with these AF lenses?
    Would like to try it out.

    I do have the Olympus pen F 40/1.4 (as well as the 42/1.2 and the four different 38mm lenses) and that is just fabulous! One of the 38/2.8 lenses is a pancake (a true pancake).

    Among the E primes, 30/2.8 DN, 30/3.5 macro (only for that- macro), 24/1.8, 50/1.8. All work well for me.

    The rumored 30-35mm "fast" prime is most likely an f/1.8 lens just like the other two fast primes. I do not think Sony's current CDAF can handle faster lenses.
    nice vivek, you have a good set of pen lens. I have to ask thoguh how does the likes of the 40 f1.4 pen f perform against the sigma 30 f2.8? say at same apetures of 2.8, size handling....

    is the pen f 40 1.4 bigger than the sigma?

    Hi Michiel, Whatever an E lens can do, these Sigma DNs also can do. I think the "shot gun" shutter gets activated when you do the panorama. The output is only a jpeg, btw.

    Hi Mazor, Thanks! It is my non selling habit that saved them! With the Panasonic G1, they got to see a lot of action. Only very briefly on the NEX-5.

    40/1.4 contrast is lower compared to the Sigma 30/2.8 DN but probably has more details- ie., if you use the pen F lens in contrasty light, you can have them all.

    The size is smaller. With the adapter, about the same. The diameter is smaller (43mm filter vs 46mm of Sigma).

    FWIW, I only have SanDisk SD cards. This behavior might be different (for the better) with the Sony cards which are reported to be more efficient.
    The behavior is inconsistent for my on my 5N (with the Sigma or Sony lenses.) Sometimes I get a white screen, and the camera takes a couple of seconds to stop down. Other times it turns on and is ready instantly.

    At one point I thought formatting the card in camera after transferring images solved this, but now I'm not sure.

    Re: Sigma 30mm f2.8 DN

    madmaxmedia, i have never experienced the white screen just after waking from sleep with my 5n.

    Tested with legacy dumb adapter, e mount and conurus ef to nex smart adapter, apeture on conurus and sony snaps opens real quick to last apeture setting.

    If you think this is a memory card issue try powering up without one? If it still does the white screen, send 5n for servicing.

    thanks vivek for that, my 40 f1.4 penf just arrives yesterday. It's second hand condition is absolutely mint. Mounted on my nex its super tiny. Loving the 1.4 for low light an!its really sharp wide open, with no vignetting. Not sure if I need to get sigma any more being two stops slower lol, unless sigma bring out an OS version, then the ball game changes.

    Re: Sigma 30mm f2.8 DN

    Douglas, I will be processing the Perar 35/3.5/NEX-7 images from a retreat last week tomorrow, along with some GXR/CV 35/2.5 images from Italy (it's been a very busy period) before deciding how good the Perar is..

    I sent back the '7; a finder fault, and will get the replacement soon. And in the meantime, the OM-D arrives... and I have the 25 'Lux waiting for it.

    So: many options around the smaller sensor cameras right now. As I mentioned elsewhere, for many reasons I am looking for a one-camera solution—the OM-D with the Panny 7–14, Panny 20/1.7, the Panny 25/1.4 and the Oly 45/1.8 could be it.

    Shooting and processing first though, before any selling frenzy! I do like the APS-C 24Mp Sony sensor and much else; if only it could use the CV UWAs elegantly...

    Re: Sigma 30mm f2.8 DN

    Yeah, it's a tough call, Kit. That OM-D looks great, although I'm not thrilled with the prism hump, which would force me to go back to the size issues that I had with the 5N+EVF.

    Keep in mind that, since the m4/3 sensor is smaller, all of those lens' aperture equivalents are around a stop slower when compared to NEX, so they're not THAT much faster in real use. The Panny 20 and 25 are a little faster than the Sigma 30, but a little slower than Sony 24, and the 45 is a stop slower than the Sony 50, in terms of real use equivalence. The Panny 25/1.4 sure looks amazing, and that would be the most tempting lens of all, for me.

    That being said, I can't recommend the Sigma 19 and 30 enough for the NEX-7. I'm not sure I've used a sharper lens on any mount than the Sigma 30. It certainly seems to give the Contax G 45 a run for its money, which shocks me.

    Re: Sigma 30mm f2.8 DN

    Hello Douglas,

    Re prism hump: the whole body plus finder is still pretty flat, though; the 5N's EVF (like the GXR's sticks out in the depth/thickness dimension)—and that's what makes it so hard to pack in a small space. The NEX-7 is fine in this regard.

    Yes, interesting times for sure for small (relatively!) sensor cameras. I have always preferred the look of larger sensor images, but as you know, used two copies of the great Nikon 14–24 on all of Nikon's best bodies—and that was a lens I NEVER took on a walk, just for pleasure.

    The same EFOV on the OM-D would be a completely different experience. And, for UWAs, the extra stop of DOF is no problem at all. My concern is what processing route to use to get over the barrel distortion of the 7-14: Uwe has suggested LR4, others DxO, and these are options, but I use Aperture for casual work because of the gallery function. Still thinking on this aspect, and the CV 12 on the GXR has no distortion problems.

    A replacement body for my NEX-7 is on the way (EVF problem); I know I can use CornerFix on the CV 12/5.6 files for the shading/colour cast, but a) it's an extra few steps (NEX-7 does not do DNGs which apparently this program needs) and b) I have read here that detail is smeared in the corners and on the long edges, so not sure what to do about that.

    My desire for a single camera is simply economy of space (one body, a few lenses) plus I want to be able to really *know* this one body. Honestly, I am tired of changing gear so often!

    So: I will trial the OM-D while on my next trip (Canada, and AZ) and make a decision then. It might just be GXR M for the UWAs; its 12MP are quality, no-problem ones, and the NEX-7 with the Sigma 30 and the Oly 50 (and some fine CV lenses on the Hawk's adapter). Still two bodies, though....

    What Sigma did with the 30mm is hard to believe. A USD 200 lens with a performance on par with Leica's best and lifetime warranty inlcuded (at least in Europe).

    Re: Sigma 30mm f2.8 DN

    tsammyc on the clubsnap forum took this pic, showing how the OM-D is about the same usable height as the 5N with EVF attached, which would be an issue with my new bag setup that I really like. My NEX-7 fits very snugly. The lens size is nice, though, but that would most just affect me in terms of aesthetics.

    Re: Sigma 30mm f2.8 DN

    Yes, Douglas, looking at that pair, I can see your reservations re. the 'hump'. I am looking forward to using just the Siggy 30/2.8 on the NEX-7 when I get the new body. It will depend on which arrives first.

    If it's the OM-D, I'm very inclined to get a Panny 20/1.7 for it, and just take that. If it's the NEX-7, I will attach the Sig. 30 and take only that.

    The Sony 50 is a large lens, relatively speaking, isn't it?

    Re: Sigma 30mm f2.8 DN

    Looking again at all this, I wonder if we should start a thread doing a 'pluses' and 'minuses' of the 5N, GXR, NEX-7 and the OM-D? Certainly that's what I have been wrestling with.

    Where would such a thread go, assuming interest?
