    I found this page that shows the GM1 with various lenses mounted to it. The shot of the Oly BCL say "with f/2 mod."


    I did some searching, on this forum and Google, and couldn't find any other mention of such a mod. Anyone have intel on this? The BCL is a pretty rad toy, but at f/8 it's sadly not suited to indoor shooting. Opening it up to f/2 (or even f/4) would make it a lot more versatile but the idea seems too good to be true.

    No pics of what or how but sounds interesting. I love my BCL! I leave it on the body when in the bag and often just use it rather than change lenses when those things happen that you just have to take a picture of. It works great in bright sunlight or with flash but sucks major in low light. An f2 version would be nice. It might also be possible to mod the "aperture disc" to an f4. This way you gain light but don't compromise the image quality as much.

    There was a post on here I read not too long ago about someone making the BCL an f/4. If f/2 is really soft but f/8 requires such slow shutter speed, f/4 would be good. There's that guy on ebay that glues lenses into old body caps and I want to buy one that's relatively sharp and fast but I guess it'd be hit or miss

    I love my 15BCL, but I'm still interested in making it an f4.

    Any more updates? Anyone buy one from the guy on ebay who glues lenses into body caps? Anyone try modding a BCL; or making their own?

    This guy has made his into a macro lens which seems like a great addition to any bag!:

    I made the macro modification on one of my BCLs... It gets real close...Here are some samples..



    Works best for me in B&W...

    Here is an image taken with the BCL with the F/2 mod (IMO the image is too soft, and more of a "fun" thing to do):

    ^the BCL renders toy like images after the f2 mod is performed... the thought of an F2 BCL was in fact to good to be true. I still want one though.

    Fascinating, I like these kind of hacks.

    That looks horrible. That looks about on par with what I got out of my first cameraphone (over 10 years ago, 0.3 MP unit). Why anyone would want to use their $1,000 camera to take pictures like this is beyond me.

    I'm curious what it'll look like at f/4 or f/5.6, it makes even the E-M5 "pocketable" for an semi-acceptable "I don't have my lens on, but I could really take this shot right now..." setup.

    I doubt it'll be any better than most phones made in the past 5 years. I got an iPhone 3GS for free from a friend and just use that for a "pocketable" alternative.

    Heck, you can get used compacts (that are smaller than an OM-D with the BCL) for the price of the BCL all day long and get better pictures and at least have zoom and better IQ.

    He mysteriously disappeared from my watch list. I messaged him before but I don't remember when and I'm on ebay so much it would take forever to find. I'm going to look when I get home.

    I know, that's what I want to see too. F4 would be 2 stops and f5.6 would be 1 stop. F8.0 ISO3200 is fun but ISO800 would be a lot more fun!

    And to you other guys acting as our fathers and telling us what kind of boys we should like, the boy we like is a 15mm body cap lens. And we're here to "fix" him and make him a better performer!

    When I say "pocketable" I mean it in a different sense from the people dropping a Canon ELPH into their tight fitting pants rear pocket and then sitting on that. I'm notorious for being one of the few(or only?) people that mounts a Sigma 18-35 f/1.4A on my E-M5 as a walk around lens. Having the E-M5 conveniently ready at any time with acceptable shutter speeds and decent sharpness is better than trying to fiddle with a smartphone to have less than ideal controls or to dump a few hundred on an advanced compact that is either large (G1X II) or costly (RX100 II), not to say that they're bad but an existing solution is already here.

    So having a f/4 BCL with "a little less" sharpness towards the corners and edges would be beneficial. I mean, after all it is "just an expensive body cap." I don't expect it to perform like my Sigma 18-35 f/1.4A on a Speedbooster stopped down to f/5.6, or remotely anything close.

    I don't think I'd want it to be faster. I like the flare and starbursts you get when you point it into the sun.
    The magic happens when you do everything wrong. It's all about being in the moment.


    But that macro mod, on the other hand...

    We're going to have to agree to disagree here. You brought up two of the most revered and most expensive compacts as examples, which isn't really a fair comparison. With what has been posted on this thread, I fail to see how an average smartphone or a $50 used compact couldn't provide the same results (or far better). We're not talking about "a little loss of sharpness in the corners" look at that photo that was posted of the house/yard. It looks like it was taken with an onion.

    I'm usually a fan of the 'soft' look but the samples provided look pretty unusable to me.
