Rokinon 7.5mm MFT on EPL5 sweet spot and focus

26 July 2014 - 11:10 AM

Hey guys (and gals),

 

I've got an Olympus EPL5 (housed in the Oly PT-EP10) and have recently added a new port and lens combination (currently shoot mostly the Oly 9-18mm zoom in a Zen 100mm port) in the Athena 100mm dome for the Lumix 8mm fisheye along with the Rokinon 7.5mm fisheye. Since these are very close to the same focal length and physical size, I do believe this combination will work well.

 

So... since the 7.5mm fisheye is a fully manual lens, I want to set this up for nearly any circumstance where I would be shooting say from 1ft out.

 

From reading, I've decided that the aperture sweet spot should be right about f8.0 (I've read that it could be from a low of 5.6 to a high of 11.0, with most agreement on 6.8 to 8.0). So I've experimented just a bit (all on land so far) and found that if I set my focus ring infinity index mark to align with the aperture ring index mark (between 3.5 and 4.0) that I seem to get very good all around focus on shots from about 8" and out (again - this is @ f8.0).

 

My question to you is: [A] does this seem correct to you? [B] any suggestions? [C] How might this change when I place this in the Athena dome?

 

I'll plan to follow-up with a review (including whatever I learn) on this combination...

 

 

Thanks in advance,

 

Jim

 

PS - any tips on dual strobe positioning for fisheye?


Lots of Oly SP-350 gear! cameras/housings/H&W ttl/strobes/cords/trays/etc.

22 July 2014 - 11:54 PM

Hey everyone! I have some Olympus gear here that might appeal to the budget conscious beginner U/W photographer...

 

If you are looking at this, you probably already know about the legendary Olympus SP-350 (was Cathy Church's go to rental and teaching U/W camera until the PEN cameras came along).

 

So let's just say that this is a very capable starter with RAW mode (supported by the last 3 versions of Photoshop) , full manual control, and lots of upgrade possibilities! (for those who don't know about it, just go do some internet research and you'll find out what we're talking about).

 

I've been teaching Basic U/W Photography for a few years and these are cameras that I carefully selected to use for loaners and some for sale (see my prior posts on this camera), and some of these were cameras that we used on trips (so easy to lug around in your dive bag). But I'm moving on and time to see these go to a good home for a newbie who'd like something they can afford but also is quality they can use and build on - or even those who still love and use this setup (it is way cool)

All prices are OBO and I will mix-n-match (quote) any combination or setup you'd like. Prices do not include shipping (but I'll work with you on that depending on what you want and what price you want it at). Cameras do not include batteries, chargers or memory card (but I have extras I might include - or ask) and I have most original boxes, manuals accessories, etc. (as long as you'll pay the added shipping cost). NOTHING HERE HAS EVEN BEEN FLOODED - every item here is in very good to like new condition and 100% functional.

 

Bottom-line: I want to move this and I really want to see this stuff go to a good home. So tell me you story and move me to accept your offers.

I have 100% perfect reputation with ebay (score of 574 ID = coach*jim since 2000) and on every forum I’ve ever sold anything (and typically I get feedback that notes condition is even better than I described). But I always will listen to any complaints you might have if this is not what you expected upon inspection/testing. Even if you change your mind, I’m happy to refund everything except shipping as long as it’s returned back to me in same condition and all original materials.
