    I was wondering if anyone tried the Oly 8mm fisheye on both OMD EM-1 and EM-5 (old version). I plan to keep it on one of them during a trip to Italy and not sure which one of the cameras works better with it. The other camera will have Pany 12-35 on it. Thanks for all the advice

    Are you talking about the Olympus 8mm f/1.8 fisheye for m4/3 or the 8mm f/3.5 fisheye for 4/3?

    I don't own one but I've tested one in a store, plus I've shot using the Samyang 7.5 FE on both E-M5 and E-M1. I'd say both bodies would work reasonably well, the more important thing is which would you prefer for the 12-35 as that is going to be more frequently used.

    Personally I'd want to be using the E-M1 most of the time with the 12-35 due to better ergonomics. The 8mm by comparison is lighter and smaller so it would be fine on either body. Another consideration if you plan on using the 8mm for astrophotography is that the E-M5 has less long exposure noise compared to the E-M1.

    I am planning to use it for street shooting in narrow spaces, so I guess em-5 would be fine.

    The Oly 8mm fisheye is longer and heavier than the 12-35 2.8 (when retracted) :) Little less chubby, though!

    Ah so it is... not by much at all though, by the time you factor in a possible hood for the 12-35. Still, given how much more the 12-35 will likely be used, I'd still say put that on the better body.

    Makes sense. I remember reading somewhere that it's important to keep horizontal line even to reduce distortion and em-1 has the level feature. I gues i can slways adjust in pp

    The perceived wisdom is to keep the horizon in the middle of the frame in order to keep it flat rather than have it curve. That's correct, but it's only part of the story.

    Any straight line which passes through the centre of the frame will remain straight, no matter what its angle is. You can tilt a horizon like a sea/sky line and it will remain straight PROVIDED it passes through the centre of the frame.

    Once you move straight lines so they don't pass through the centre of the frame then they are going to bend. How much they bend is going to depend in large part on how far away from the centre of the frame the line is placed. The further away from the centre of the frame, the more curvature will be introduced.


    The E-M5 also has the electronic level indication as well as the E-M1.

    Does this lens have a " sweet spot" for street photography?

    Sweet spot and fisheye is a funny concept... but like most f/1.8 lenses it probably reaches a peak around f/2.8.

    about 3cm directly in front of the lens. ;)

    I have the 8mm,1.8. It works fine on my e-m1 and I expect it will work fine on the e-m5. Focus is a non-issue with these things. Size is relatively small so there's no real advantage to using it on the e-m1.

    Prior advice was good...focus on usability with the 12-35. The 8mm will easily work with either.
