    Thanks, Mazor.

    The C-V lenses only allow close-ups. Magnification ranges of 1/3X to 1/5X.

    The macro shots posted above are 3X life size.

    FWIW, as I already said, I do not have the M mount Cosina lenses. Only the LTM ones. I use them with a NEX to LTM adapter and not the Hawk adapter.

    I have lots of extension rings for any thread mount, including Leica threads.

    Good macro's Vivek!

    The SB-30 is that a second flash? SB-30 doesn't ring a bell.

    BTW What advantages, besides being smaller and less expensive, has the HVL-F20AM above the Sony HVL-F42AM of which you can swing the light vertical and horizontal.

    Re: Fun with NEX-7

    Michiel, Thanks!

    SB-30 is a tiny Nikon flash that allows manual power settings down to 1/64 (I have way too many Nikon flashes).

    Advantage of the HVL-F20AM over the others:

    Small

    Light weight (160g)

    Has more than enough light for macros like this (in fact if the pop up could be brought close to the subject it has more than enough light).

    The key, of course, is my special flash modifier. So, it isn't the HVL-F20AM that is the big deal here.

    Re: Fun with NEX-7

    do tell us vivek more about this flash modifier please

    my 15mm cv with helicoid gets at best 1/2 life size, but then I crop the image heaps and get a much larger frame of the subject.

    finally got out there (having a tire changed in Queens, walked around the 'hood)
    all with CV 12mm. also used an LCC, though shot it afterward and it's effect seemed to work fine, but to varying effect

    Re: Fun with NEX-7

    last one. all quickly processed in C1, mostly full frame, a few show more magenta corners, even though LCC applied. seems like this works but needs optimizing. first time out with this lens on the nex. it is a lot of fun

    Re: Fun with NEX-7

    Nice series, John (not a living soul in sight!)!

    Life is full of surprises- only in your Kyptonite shot, in the lower left corner there is a hint of magenta.

    Unlike, the C-V 15/4.5, the C-V 12/5.6 behaves differently (for the better) on the NEX-7.

    The veteran Kit made me scratch my head when he sold off his 5N in favor of the 7 to use with the C-V 12 lens. I understand it now.

    90mm; shooting f8 or so, using the focus magnifier to nail it; doubt I could have been so well focused with the M8. all hand held, so different for me!

    Re: Fun with NEX-7

    The veteran Kit kept his GXR M module for the 12/5.6!

    But if I do keep the NEX-7 (and I have not tried the 12 on it, so these images are very good to see), I might have to change from Aperture to LR4. I have C1Pro6, but have to admit I have no idea how to do LCCs or correct the colour casts.

    Uwe mentioned that LR does this correction automatically, but I have no experience of it myself.

    Jim, I don't see any of the edge smearing of details with the 12/5.6 and the NEX-7, either. Do you see any at full file size?

    Cheers all, kl

    Re: Fun with NEX-7

    Kit:
    using C1:
    you need a separate LCC for each lens in question
    1. take a shot at the f-stop you are using, adjust exposure to center the histogram by changing shutter speed. but put a white plastic diffuser right on the lens and focus on infinity.

    2. in C1, open that shot, open the lens correction tab (the little lens image), under LCC you are going to create a new LCC, I use the same name, maybe add text after it, "like 12mm" then select analyse technical wide angle. an LCC will be created and stored.

    3. to apply the LCC, open the image, go to lens correction, look at LCC list and select the one you created. it will be applied. you can choose several features to toggle on and off: edge color cast correction, light falloff (with a slider) dust removal (this is very useful), chroma, vignetting, etc.

    it is quite easy

    Re: Fun with NEX-7

    Hi Kit,

    These two snaps were with the 12/5.6 on the NEX-7 taken a few days ago.





    Processed through LR3 (vignetting and such). Though magenta (color shift) is there, it is nowhere near the amount from the CV15/4.5 lens.

    Re: Fun with NEX-7

    Matt Thanks, I was quiet pleased with that one. Glad you were too!

    jlm Lovely work and I always love to see photos from New York (streetscenes) outside the regular places!

    Today I did some Macro in the Hortus Botanica off blosseming cactusplants.
    Very small flowers. Actually to test two macro Minolta md macrolenses, but I ended up with th Schneiderlens on bellows. Sharper.
    Tryed lots of DOF. No photostacking (yet)

    Michiel, They look good but sharpness/detail is lacking. Which Minolta MD macro lenses did you try? I had the 50mm and the 100mm bellows lenses once. They were very good.

    Mazor, Many things can (and do) go wrong while using a bellows or an extension tube. I am not second guessing Michiel.

    Re: Fun with NEX-7

    @ Jim: thanks; that's very helpful. I am still working out whether one camera can do what I want, but knowing the LCC process is so relatively simple is good to know. And when you say "diffuser" I am guessing you mean a white plastic container (Tupperware or similar) to get a completely grey image?

    @ Vivek: I wonder why the 12 is better than the 15 in this regard? Interesting. Thanks all; I am heading off to Vancouver this morning, so will be off the air for a while. cheers, KL

    Re: Fun with NEX-7

    Vivek, I have the 100/4 and 50/3.5. Not to use on bellows I think. I forgot to bring the special extension tube for the 100 for 1:1 magnification. I tryed to use them with +1 and +2 diopters but that did not work out well. Another time.

    I preferred what came out of the bellows with the Schneider lens. These are, of course very small flowers and cropped. The last one is a very big crop and not sharp (anymore) but I just liked it. That insect in there I could not see with the naked eye.
    The first one is quiet sharp, I think. Miss my Canon FD 200/4 Macro. It was so wobbling I could almost photograph around he corner with it. It is in repair now. Very nice lens for this kind of work.
    Will be continued.

    Mazur, you're quiet a funny little joker aren't you hehe..he

    Re: Fun with NEX-7

    Kit: I use a plastic card I got with my IQ back, but a plastics store can provide what you need. it will be out of focus, but you want the diffusion to be even; if the word "Tupperware" was even slightly visible, it might be considered a dust spot! and the LCC correction would try and remove it from your image

    Jack once posted a plastic product in the MF forum, i'll look for that.

    found it:
    http://forum.getdpi.com/forum/medium...cc-plates.html

    do a search in MFDB forum under LCC correction and plenty will come up

    I also found the 15 to have a bit more corner cast than the 12, but will try and do more controlled test

    jlm, on post #21, you took some lovely street photos which you say you used a pen-D 42/1.2

    Curious did you mean pen-F? The only Pen-D I found for m4/3 is a 14-42mm

    Hi, Kit. For my profiles, I just placed a white tissue over the lens, kind of like a drum head, and shot wide open into a clear sky with focus to infinity with about a +2EV exp. comp.

    I don't believe that LR corrects corner color casts, but, rather, CA issues.

    jlm, would love to see a comparison of 50 lux against the 40 1.2 penf, especially bokeh!

    whoa you got a good lens there the 42 1.2, would love to have one, but can't afford it. :/

    Hi all. Been away for a little while, itīs always a joy to return here and watch the images you guys share. Let me share with you my first attempt at doing long exposures with the Nex7. Here a six minute exposure with 18 stops of ND filtration and the Sigmarit 30 @f/11.

    Re: Fun with NEX-7

    Tim, your beautiful bw image (and, to say the truth,also what is going on the Leica forum..)suggested me to try a high iso bw conversion with the nex 7.
    Iso 6400, summicron 50 F8.
    Not so bad, I think.
    A slightly cropped full size jpg is available on Flickr.


    _DSC1026 by sergio lovisolo, on Flickr

    D800 should be even better. A try?
