mk2 opteka comparison ( panasonic hpx170 ) 

Damn! Nice video. I've had a feeling the MK2 and the Opteka on the Panasonics are pretty much identical and this proves it. At this point it's really just glass quality which of course the MK2 is the winner

Great video. Perfect example of why people aren’t rioting for reissues like they had with the mk1 and are with the xtreme.

thanks for the comparison! would really appreciate a similar video outside in sunny weather to further compare sun flares on both (inside with a powerful enough light could also do, I guess).

good video bro! i think both fisheyes are the same

Absolutely no reason to run a mk2 when the opteka is hundreds of dollars cheaper

how do i remove the spacer ring from opteka lens? mine doesn’t come off after i attached it.

For the MK2, what size step up/down rings did you use? I caught the 77-72mm and I believe a 72-77 but didn’t catch what the other one was.

It’s needed this big spacer for the opteka to use on the hpx? Not possible to use it without the ring?

Comparison. Not review

Why 72-77mm?... If lens hvx is 82mm?... Tell me the order of the rings please
