In Topic: Are people leaving micro four thirds?

Today, 05:16 AM

I think you are over-interpreting very little data.


I agree...sort of...it was more of an observation and question than any sort of conclusion or opinion.  I am curious to see what people think about the topic.  Maybe I should have said that I am beginning to wonder if people are switching instead of saying that I am beginning to think that.  I still use micro four thirds and am looking forward to seeing what the EM1 replacement offers.

I have no loyalty or biases as to Panasonic vs. Olympus.  I would use whichever brand appeared to offer me the best product for my needs at the time I was buying.  As to this camera and underwater use, it appears the max flash sync speed is 1/160.

I don't know if you are talking about stills or video (for some reason, a lot of people choose to discuss video here instead of the video forum).  I would doubt that a housing would be available soon and there might be none, given all of the other Olympus and Panasonic models for which there are housings.  I have no idea whether this new "entry level" model is a good choice for video.  For stills, I would suggest you take a look at a GX7, EM5, EM5II or EM10.  There are housings already out for all of these and because the camera models are not newly introduced, they will likely be a lot less $.  You can use whatever Olympus or Pnasonic lens you want on any of those.  I believe the WWL-1 does work with he 12-32 zoom.

In Topic: Recommend a lens/port for CFWA on m4/3?

I have both of these lenses and haven't really found the Olympus to have more distortion or that the resolution falls off rapidly outside the center.  Here is another view of the lenses:http://www.mirrorles...asonic7-14mm_f4


Clearly, any 7mm lens will have distortion, and corner/edge softness is significantly affected by the quality and size the dome used.  Certainly if the Olympus is shot at 2.8, one could expect more edge problems than the Panasonic used at 4.0, but underwater I would expect both lenses to be used at much smaller apertures.  Also, the Olympus does focus closer.    To me, one of the 8mm fisheyes would be the best choice for cfwa, but the 7-14s would work, although limited by minimum focus distance and dome size.


Also keep in mind that if shooting jpegs, the cameras themselves will apply corrections to the images and one would get different results if using one brand of lens on an alternative brand of body (Panasonic / Olympus). 



I also would warn you about the fact that even if you have f/2.8 on the olympus you will find yourself never shooting less than f/8 on close shots. Having said that the lens is much sharper than the Panasonic but has also more distortion with resolution falling off very rapidly outside center, this happens but less noticeably with the Panasonic 7-14mm too

The roller bag is fully padded and has adjustable dividers in it.  The trick with the shoulder bag was to buy a bag with the maximum dimensions for the "personal item" bag that is allowed, and then I put a padded camera bag insert into it, which left plenty of room for other stuff.  I will try to get time to take a couple shots of the interior of the bags tomorrow.
