    What 10 to 12mm Wide Angle on the G1?

    I am looking for a short wide angle. While there is plenty of information on normal and long lenses on this and other fora. there is not much on extreme wide angles, corresponding to a 20 or 24mm FF lens. The only lenses I saw mentioned are the 12mm/5.6 Voigtländer and the 9.8mm/1.8 Kinoptik Tegea

    The Voigtländer is slow, I would like at least a 2.8; the Tegea, which I own, is too heavy (1.5kg = 3 lbs) and bulky for normal hand-held use.

    On ebay one can find numerous 10 to 12mm Cine lenses for 16mm movie film, mainly in C-mount, such as the Kern Switars. Has anyone used one of these lenses on the G1? will they cover the whole sensor area? What are the results?

    Looking forward to your suggestions.

    I'm waiting to see what the Panny 7-14 is going to weigh in at. I have the CV12 but the 14-45 lens is small enough and as fast so I have been using the kit for the moment.

    ZD 9-18 for now... lumix 7-14 to checkout soon (April?)

    The ZD 11-22 f2.8-3.5 is a little faster, but no CDAF and a bit bulky & heavy for the G1.

    Kind Regards

    I don't think there are 16mm cine lenses of that focal length that cover the sensor, most likely 35mm cine but you've got the one already.

    I sure wish Pana or Oly would come out with a 10mm prime...

    Here is a shot from an 8.5mm f/1.5 cine lens, cost me about $20, new.

    The 'MacBook' logo was about an inch from the front of the lens. Taken at f/1.5.

    The lens doesn't fit onto the c mount adapter quite close enough, so it can't focus to infinity. Makes for an interesting fisheye-style macro, though. Will do some machining for a proper fit.

    Has anyone had any experience with the Sigma 10 - 20 for Olympus cameras?

    terry, have you tried the cv 12 on the g1 at all?
    just wondering what you think.

    i am getting itchy for something wider and a 24 mm equivalent might just do it.

    Joe - this was done with the CV 12 - It works well for the G1. I bought it for my RD-1.

    thanks.
    i'm thinking of getting one so i can have a 24.
    most of my shooting is out on the street so the slow speed won't be a great hardship.

    Re: What 10 to 12mm Wide Angle on the G1?

    although it is a little outside the range discussed here i am anxious to try the 21 elmarit on my G1 (which i should have any moment now). The 21 elmarit is a bit of an orphan since most folks use the WATE in this range. You rarely see posts about it. However I find it a really nice rendering lens and look forward to trying it on the G1. Obviously the crop factor is a big issue but the only real alternative is the CV 12. I look forward to creating some comparison shots

    Re: What 10 to 12mm Wide Angle on the G1?

    I'm a bit concerned about performance of the M mount wides on the G1 after reading Reid's review and also looking closely at some of my G1 images taken with wide M mount lenses. The CV 12 looks fine and the CV 15 also has minimal distortion, but the 20's seem to be problematic. Here is a corner shot on both the G1 and M8 using the same Zeiss 25mm f/2.8 Biogon lens. 100% crops of the lower right corner. Notice the severe distortion and maze artifact in the G1 image. Center is fine.

    The Olympus 9-18 is a gem on the G1 (I don't have the G1 anymore, but I still have the lens).
    It autofocuses, it's small, it's cheap(ish) and the results are stellar.
    why not?

    Cheaper than the VC 12, and a bit faster on the wide end. Must have the Pana adapter tho.

    Re: What 10 to 12mm Wide Angle on the G1?

    not really cheaper if i have to factor in the panasonic adapter.

    i like the idea of the 7-14 but if it's priced like the oly then it's out of my budget range.
    if sigma makes a m4/3 10-20 that would be in the running for sure.

    What adapter do you need for it to work on the G1?

    The only sample pictures I saw were on this Japanese site http://dc.watch.impress.co.jp/cda/re...2/11/9815.html and did not seem very sharp.

    Where your and Brian's results better?

    Yes, the maze artifact is only generated in Lightroom. Processing with Silkypix or Raw Developer does not produce the maze pattern. The edge and corner distortion is lens specific and not corrected by software.

    You'll need the Panasonic Micro Four Thirds adapter (DMW-MA1).

    By the way, that's a pretty interesting website you provided. Thanks!

    The DC Watch site has published very interesting G1-related material in the past few weeks.

    The Oly 9-18 looks pretty good to me, and $450 (new, ebay) is not bad at all. Ideally I'd prefer the 7-14 Lumix lens with OIS and f/4 at all focal lengths, and no need for an adapter. But this looks like a lot better option than the 12mm VC lens, at least to me, in all ways except size.

    Well, I don't understand Japanese, but the photos and captions are pretty self-explanatory, and Google translation helps somewhat with the balance.

    Although I did find this particular translation interesting.

    Hmm, methinks the Lumix 7-14 will not include OIS although a constant f4 is pretty certain.

    No OiS? I think I read that somewhere, is that confirmed? Even so I'd still prefer the 7-14...

    Re: What 10 to 12mm Wide Angle on the G1?

    need to think some more about the oly 9-18 plus panasonic adapter.
    i doubt that i will be able to afford the lumix 7-14.

    or maybe i just to be satisfied with the 28 end of the kit zoom.

    I am with Jono. I realize this lens requires the 4/3 adapter which is pricey, but the 9-18 is in my opinion better on the G1 than on the Oly bodies including E3/E30. The lens is an F4 and viewing in an optical vf is dim. This is not a problem with the G1 EVF. The 9/18 is small and even with the adapter it fits nicely on the G1. As Jono points out the IQ is stellar. As Jono says - why not?

    Best regards. Terry.

    Is it the Cosmicar 8.5mm f/1.5? Any luck with getting more focus from it? Makes for a fun self-portrait rig with the fold-out LCD screen - although not too flattering apparently!

    Yes, I'm with Jono too... oh wait, this is a circular reference! good to know there's lots of agreement here...

    Anyhow, the ZD 9-18 with 4/3rds adapter is currently the best solution for UWA on the G1, and we'll know how the Lumix 7-14 compares soon. I took the 9-18 with me to Focus on Imaging yesterday - using it on the E-520 for the built in stabilisation, while remaining very lightweight.

    Here are a few snapshots, all at 9mm, f4 (I love UWA)

    Who needs small? buy a cannon for your canon!


    I was curious about this stand... sensor cleaning? what's that for?


    Couldn't get anywhere near the model... what a rugby scrum! ah well, with 9mm you can wave in the general direction and get a reasonably framed shot


    ...and if that doesn't work, think laterally and shoot between the scrum's legs


    Do you do trade-ins?


    ...and yes, for me - small is beautiful.

    Kind Regards

    Re: What 10 to 12mm Wide Angle on the G1?

    I know I'm a bit of a cheapskate over this, but even though I'd rather like to add the 4/3rds to m4/3rds adaptor giving me some more flexibility for other lenses (including possibly the 9-18), extension tubes, etc, I'm really not wanting to pay a premium for it. The $169.95 from Panasonic is bad enough, but most other places are asking upwards to over $200 (USD) for it. I'm on the B & H list for it at $139.95--but its been OS for a good while there. I've read that jinfinance on ebay is going to have one in March-which should be less--but is there a reason this one is both not available from anyone else--and is demanding a premium (guessing its because of supply and demand)?

    Diane, the Panasonic DMW-MA1 has electrical contacts, unlike the other adapters, so that AF works (with some) of the 4/3 lenses, so the camera can sense the focal length, etc. Interesting that RJ says he'll do his own version!

    If you need one, order from Bill Wilby from this forum, that's where I got mine:

    I know Diane, it's a scandalous price... but the 4/3rds adapter was an essential part of the G1 for me - I didn't want to be limited in IQ to the Lumix kit lens.

    I hadn't considered the 'active' element of the Panasonic adapter - I suppose we'll be stuck with the official part to guarantee compatibility... guess I don't feel so bad about laying down the cash now, I was expecting a cheap chinese clone any day now.

    Kind Regards
