    So this last weekend I took my E-P2 and lenses to shoot a snowy waterfall. The widest prime I own is a Fujinon CF25B 25mm f/1,4. This is the lens that stays on the camera the most. The only auto focus lens I own is the kit 14-35mm f/3,5-5,6. I found myself using the kit lens for the first time almost ever because my widest prime just wasn't wide enough. When I got everything back to the warmth of my room I found myself disappointed in the colors the kit lens produced compared to the Fujinon.
    So! I want a good wide angle!

    I've been looking at either another c-mount conversion or picking up one of the many 17mm f/3,5 wide-angles and using a Metabones speed booster.

    What do you do for wide stuffs? How do you like it? What else have you seen? What is your opinion of it?

    just get a 12-50; dirt cheap and 12mm

    I use a 7 - but it's not dirt cheap :smile:

    $500 isn't bad for 12mm f/3,5
    My wife has an OM-D EM-5, so we'll likely be picking up some weather-sealed lenses for her, starting with this one.

    That would be cheaper than a Metabones FD speed booster + 17mm f/3,5, which would make a 12mm f/2. I would say it's not exactly worth the added speed, but is it worth it to be able to be able to go down the speed booster route?

    EDIT: It's a 1-stop increase in aperture, so it should actually be a 12mm f/2,5.

    If you are considering metabones speed booster + a legacy 17mm 3.5 to make a 12mm F2, why are you not considering the small and wonderful native Oly 12mm F2, which can be had used for 5-600$, and has autofocus. Oh yea, did I already mention that it is awesome?

    Honestly, going the legacy route to go wide is not the best option on the m43 system.

    The Oly 12 f/2 is arguably the ideal, but I'm looking into the 17mm f/3,5s and the speed booster because I've heard good about either product alone, and I think the FD speed booster would allow other fun.

    I haven't seen the Oly 12 f/2 that cheap. I'll have to look harder. Thank you!

    If you are serious about getting a legacy 17mm + speedbooster, you may as well pick up a new Samyang 14mm f2.8 (for an effective 20mm f2 - sharp wide open) that will blow any legacy 17's away (and probably the Olympus 12mm). I just picked one up for $AU280 second hand - you may be able to get a better deal depending on your local market. But if you don't have any other lenses to use with the speedbooster, it gets expensive. But with the Nikon Speedbooster, you could also add the Voigtlander 58mm f1.4 for an effective 85mm f1...

    Samyang 14mm f2.8 on Nikon Speedbooster...

    I've been eyeing that Samyang, also the 35mm f/1,4 for a fast normal on the speed booster. Both are rather large, but still very tempting.

    For cheap, fun and wide, you could do a lot worse than the Panasonic 14/2.5 + DMW-GWC1 wide-angle conversion lens for an 11mm AOV for $300.

    I have no experience with wide-angle converters. I'll look into this as well. Thank you.

    FWIW, a speedboosted 17/3.5 will become a 12/2.5, not an f/2.

    I think it's a nice option. You get the wondrous glory that is manual-focus vintage and you also open up the option to speedboost many other lenses giving yourself a fleet of f/1 or better lenses that DSLR users can drool over.

    Isn't it a 1-stop increase? Which would mean I was still wrong, it should be a 12mm f/2,8. Thank you for the correction. I'll append my original statement.

    I use a Lumix 7-14/f4 and m.ZD 12/f2 for wide-angle stuff.

    Neither are cheap, both are exceptional.

    Multiply the aperture by 0.71 - there's your new f-stop. 3.5 * 0.71 = 2.485, also known as f2.5 in simpler circles

    Nope, delightfully rectilinear

    Their advertising specifically says
    Everywhere they make speed comparisons this seems to be true.
    I haven't put my hands on one, so I can't say in practice that their advertising is true. I have to ask then: have you used them and noticed a 1EV difference, or something else? Have any reports otherwise you can cite?

    Awesome. I'd like a bit faster than that, but the world is all about compromise.

    There's the SLR Magic HyperPrime 12mm T1.6 (probably the equivalent of f1.4), but it's fully manual and $600USD.

    http://www.adorama.com/SLR1216MFT.html

    Really though, what do you want the speed for? You mentioned landscapes, and I'm not sure what kind of landscape scenario is going to require faster than f2?

    I've been looking at the SLR Magic as well. I'd love to find one of those used. I'd also love a 25mm f/0,95 used as well.

    Most of my want for speed is being able to keep shutter speeds fast or shrink DOF for a foreground object. Flexibility, really. Also, I like taking pictures at museums which sometimes don't allow tripods. In museums I've been shooting with the Samyang 7,5mm f/3,5 and correcting the distortion in Digikam, but I only have one, and when my wife wants to use it I don't argue. She seems to enjoy it much more than I do.

    To reduce f value by one stop, multiply by 1 / sqrt(2), or 0.71.
