low light focus tips for Olympus m4/3 60mm macro?

25 March 2015 - 04:30 PM

I've finally picked up the Olympus 60mm f2.8 macro lens and will be diving with it for the first time this weekend.  I need some tips please!

 

Testing around the house last night, the lens can be slow to focus and hunts quite a bit in low light situations. I use a red focus light at night since I'll be shooting mandarinfish which can be skittish with brighter white light and don't allow a lot of time to get the focus right.  I realize I can prefocus but that is tough to get right with a rapidly moving subject.  Is there anything I can do to improve autofocus speed in this situation? 

 

I also notice that even with the focus limiter switch set to the closest range (0.19 - 0.4 m), once it loses focus, the lens will hunt through its full range out to infinity, which doesn't seem right. 

 

BTW I'm using an OM-D EM-5, which focuses very fast with the 12-50mm lens in macro mode under the same conditions. 


Is it possible to test a wet lens above water?

This is possibly a really dumb question (but I'm OK with that): Can I test a Subsee macro lens on my housing without getting in the water?  My local retailer has the lenses and i would like to take my camera and lenses and housing to the shop to see whether any combination works for me.  I'm a dummy when it comes to lens optics so will appreciate any tips.   


Bohol: recommend a photo friendly operator

05 May 2014 - 05:42 AM

I'll be in Bohol soon on a family holiday and have a couple of days free to dive. I'm looking for a good operator that is accustomed to photographers. Recommended sites welcome too. I'm an advanced diver most interested in walls and pelagics on this trip as I get my fill of macro in Anilao on a regular basis. TIA
