In Topic: Focus Settings OMD-EM5

11 March 2014 - 10:49 AM



I have also noticed a problem with the EM5 focusing with my 12-50 lens when shooting macro.   I was night diving in Raja Ampat.   My shutter speed was set to 1/250, with 200 ISO,  (on full manual setting) but I had quite a lot of difficulty with subjects that had very low contrast.    Even using my Sola 800 at full power didn't help.


I ended up focusing on something else close by, locking the focus, and then "rocking" to adjust the focus.     Is that just the nature of the EM5?


I was a previous D200 shooter (Subal housing).

I have both ports and both lenses and have been to Lembeh (although not with the OMD EM5, but with a Nikon D200).    I have also used the Subsee +5 and +10 diopters with the M77 flip diopter ring.    You can easily use the 60 mm lens in the 12-50 port without any problem.   I definitely would not buy the 60 mm port.   The 60 mm lens functions much like the 105 mm lens in the 1.5 crop factor cameras.   The 12-50 mmn lens  functions more like the 60 mm lens in the 1.5 crop factor cameras.    So which one you like will depend on what you like to shoot.   I couldn't get the +10 diopter to work with the 12-50 lens (at it's maximum focal length) without some vignetting.   Also you have to get so close, you will be touching the subject.   For me, the diopters are only useful on the 60 mm lens.    The +5 on the 60 mm lens didn't seem to provide much more difference in magnification from the 60 mm lens by itself.   So my configuration is the 12-50 port, 60 mm lens, and+10 diopter.    Now that I've said all of this, I've only shot about 3 dives with this set-up.    I took it with me to Raja Ampat last month, but found 12-50 and my wide angle lenses more useful.  Going to Lembeh, you will definitely use the 60 mm lens.......and probably the diopter.  Hope this is helpful.

Six months ago, I changed from a D200 in a Subal housing to the OM-5 in a Nauticam housing.     I have shot the 45 degree Inon viewfinder in an Ikelite housing and the straight Subal sport viewfinder with my Subal housing.   I feel strongly that these viewfinders were necessary for the older, non live-view digital SLRS.,,,for shooters like me with old eyes.


However, I would recommend against buying any viewfinder for the OM-5 in the Nauticam housing for these reasons:


1)   These viewfinders are very large for this small of a housing.

2)   I feel they are not necessary because: 1) I find myself shooting in the "live view" mode more and more;  2) The live view viewfinder is really large, compared to the D300 and D200 view screens; and 3) More   importantly, the automatic focusing mechanism has been very sharp.   I find myself not worrying about having to actually visually confirm that I have focus.

3)   Both of these viewfinders are made to be added to the Nauticam housing very easily by the user if you want it later.    This is not true of the Subal or the Ikelite housings--these must be added by someone who knows what they're doing.   I would try it first and see if you feel you really need it.  You can always buy it and add it yourself later.


If you need a viewfinder added, I would go with the straight one.   The advantage of the 45 deg viewfinder is that you can get really low for macro.   The big disadvantage is that when you're following any fish that's moving, it will be hard and un natural with the 45 deg viewfinders.    I never got used to shooting pelagics with a 45 deg viewfinder.    I'd settle for having to get on my stomach for the macro shots in order to not miss the exciting pelagic shots.

I found your set-up innovative and interesting.    Although I have a Seahorn snoot, I've been messing around with something more portable.  I have a number of questions for you.


1)   What is the white thing that you are using to connect your fiber optic fibers?

2)   What are your fiber optic fibers (manufacturer and model)?

3)  What  (yellow) connectors are you using to connect your white thing to the arms containing the fiber optic fibers?

4)  What are the yellow end pieces?

I posted a couple of months ago when I first got the 12-50 port.    Currently, I'm using a beer koozie, cut down to size.   My advice, get the solid rubber koozies.   I advise against the thin neoprene koozies since they tend to rip apart.   You can get them on Amazon.    They are a little hard to put on underwater with neoprene gloves on....as I dive in California, but, with a little effort, you can do it.   They protect well and aren't easily knocked off.  I'm still looking for a more ideal cover.
