    I had admired the photos taken with the Rokinon 7.5mm fish eye, but I didn't really appreciate how wide it was until I got my own copy of it... here's a sample of just how wide it's field of view is compared to the 12mm end of the 12-35.

    So here's the setup:

    And from the side - I didn't measure the distance to the closest most spice bottle, but I'd guess about 6"

    This is what you get with the 7.5 mounted on my E-PL1

    And the same location with the 12-35 @12mm on the E-M5

    Yeah, the 7.5 is insanely wide. I often get my feet in the pictures :wink:


    What profile did you use to defish in LR?

    Along with 98% of HDR and mini toy village look I detest, with a burning passion, fisheye shots ... that said the defished shot does look a lot better than the "unfished" one

    Yea I've caught my feet in a couple of shots as well. I've found this lens to be a fun departure from the rectilinear norm and is my first foray into the world of round. Its not suitable for a lot of things but it is a new challenge to find ways to use it creatively.

    Hi Mike, I'd guess there's nothing personal in this, it's such a distinctive look some are bound to hate the effect, much as others love it.
    For me, thanks - I'm looking to buy one of these and your post's really helpful :thumbup:

    This lens is great, my top 5 favourite and 10 out of top 25 favourite shots in Flicker are from this lens.
    Every time I use it, I feel creative.

    quite so sir indeed the point I was trying to convey was that once it was "defished" it actually didn't "offend me" much at all :wink: Useful for interirors and possibly a lens that might appeal to myself...though I may not buy any additional lenses for my GX1 - or if I do just one prime around the 17-20 mm - purley as I already have so much camera gear I really can't justify buying several lenses for it.

    If I ever move on my DSLR's then I might re look at it :)

    oh I wasn't particularly offended, more amused. It seemed an odd response in light of the intended reader... those who might not be offended by highly distorted images :biggrin:

    This lens fills two roles for me; an additional creative path I haven't tried before, and the possibility of its use as an ultra wide rectilinear lens that I don't otherwise have.

    If i still used DSLRs i might not have been interested either.

    I'm happy if this is of any use to anyone besides myself.

    so to defish it did you just play around with various lightroom profiles till you found on you liked the look of or some other approach ?

    tis a nice looking lens too ... not that that's very important lol

    There's a thread over at DPR where a gentleman (I call him that if for no other reason he did this for free :) posted some Camera RAW profiles for this lens. He has 3 or 4 variations, each doing some different form of math magic...

    Rokinon/Samyang 7.5 Lens Profiles: Micro Four Thirds Talk Forum: Digital Photography Review

    Farther into the thread he posted a response to how wide is the defished image and the disadvantage of doing that. It's interesting at least to get a small amount of insight to what's going on. I also saw that others were applying the Nikon 10.5mm fisheye profile to this lens - I've tried that and found it worked pretty well -

    it is a nice looking lens -

    Anyone thinking of getting this lens should also check out the Open Source program, Hugin. It is (mainly) a graphical interface to another Open Source toolkit called PanoTools, to makeit much easier to use. Along with stitching Panoramas (as the name suggests), PanoTools can do "reprojection", so turn fisheye into rectilinear or a whole host of other projections. One of the projections supported has been nicknamed Pannini (although this is a typo, because its named after a painter called Panini), which is the exact same projection that Fisheye Hemi uses. So as long as you don't mind opening and resaving files instead of calling up a plugin, you can get what Fisheye-Hemi does for free.

    Thanks for the heads up - I've used that software for pano work but haven't yet tried it for defishing... I prefer staying inside LR when I can and only exporting the results I want but it's always nice to have options.

    Thanks for this. I'm a new OM-D user and I'm thinking of picking up this lens before heading to Glastonbury festival in June.

    I'm coming from Canon, where 80% of my shots were taken with my Tokina 12-24 at 12mm, so I'm a big fan of wide angle.

    I used to have the Tokina and loved shooting with it at 12mm as well. I'm taking the 7.5 with me to Scarborough Fair this Saturday just in case an opportunity arises.

    Thanks for commenting.
