#366409 A6000 >> Macro >> has anyone succeeded using the canon 60mm m...

Posted by bvanant on 23 October 2015 - 10:43 AM

I have shot with the canon 60 and adapter. What I do is set the focus long before shooting; and use the manual move the camera forward and back to get the shot.  Works fine if a bit slow.  Trying to use autofocus with any of these adapters (so far) seems hopeless.

It works (kind of) but in my hands at least it is terribly slow.


#365400 What is the purpose of a Dome?

Posted by bvanant on 19 September 2015 - 09:08 AM

I think we are talking apples and elephants here. I thought the OP was asking about a dome port, not a dome diffuser for a strobe. Bill

You will need both. The bits that I use regularly are from NightSea and FireDiveGear. Both companies make great stuff.


#365298 What is the purpose of a Dome?

Posted by bvanant on 16 September 2015 - 03:25 PM

Dome ports allow you to shoot wide angle photographs more easily. You can use them with any lens but in general you want them for wider lenses both rectilinear ones and fisheyes. The dome is acting as a big optical element and it allows you to shoot a wide scene but of a "virtual image" that is created by the dome. The virtual image is between 1 and 15 inches from the dome (depending on the dome size, larger domes lead to virtual images further away).

#365088 Workshops on OMD-EM1 Mirrorless Camera

Posted by bvanant on 09 September 2015 - 12:37 PM

i can highly recommend the workshops run by Mike and Luca if you can make them, unlike many other workshops they don't take cameras with them on dives, but are there to help the students.  Otherwise you can go to a Underwater Photo society if there is one near you, at LAUPS we help individuals all the time with everything from the basics to advanced stuff.


#363493 SLR vs. Mirrorless. What is the best camera for macro?

Posted by bvanant on 22 July 2015 - 06:10 PM


I took my 7D and Oly EM-1 on a trip to Indo. At the end, most guests thought the EM-1 photos are better.  As for macro, a lot depends on what you want to shoot and how small you want to shoot. The Canon 100 and the Canon 60 are great lenses but shoot 35 mm full frame.  The native OLY 60 shoots 17 mm full frame. Any diopter improves things proportionally, i.e. a 2x diopter for the Canon gets you to where the OLy is natively and the 2x on the oLY gets you to 8 mm full frame.  That being said, and if you shoot raw, to me at least you can't tell the IQ apart very much. You could go Canon 5DIIIS with 50 MP and crop like mad, but I would rather carry around the smaller/cheaper system.



P.S. Going to God's Pocket in Sept, hope it is as good as the Alaska Trip.

Hope you are well and diving a lot. For me if you are shooting tiny stuff (like the small spiny lumpsuckers) then the olympus om-d e-m1 (or the new em5-II) is the best option with the only 60 macro lens. Out of the box it is 1:1 (on the smaller sensor) meaning it is 2:1 compared to full frame and 1.5:1 compared to crop sensor DSLR. Then add the CMC (or my old SMC) and you are at 4:L1 compared to full frame.  I have been shooting that for a while now and for tiny stuff it is quite nice.



#363064 GoPro Macro Lenses- Anyone have any experience with them?

Posted by bvanant on 09 July 2015 - 03:53 PM

You can get pretty nice results from them if you use the focus stick religiously, the depth of field with them is ridiculously shallow and you need to be at just the right distance. that being said, if you nail the distance the results are quite nice.


#362390 UV techniques

Posted by bvanant on 18 June 2015 - 09:21 AM

What I do if it is a dim fluorescence is to set manual focus at a known distance then shoot from that distance, although for many fluorophore types my EM-1 focuses fine.


#362353 Debating my first set-up

Posted by bvanant on 17 June 2015 - 11:48 AM

A lot depends on your budget and how much you will dive and most importantly what you want from your pics. If you want to show your friends cool things you find, then compacts are fine; if you want to hang pictures on the wall then you will want something better, and if you want to win underwater photo competitions then you will want something different again. I would start with something like the EM-5 and the 12-50 lens (sort of all purpose) and see which way your photography wants to go. You will need the housing and a strobe or two and a focus light. 

This will be nearly $2500 but will last for a long time.

#362145 Silcion Lube for Nauticam o-Rings?

Posted by bvanant on 12 June 2015 - 02:33 PM

Tribolube 71 and Christolube are both fine for ALL types of o-rings. 

Other wise you might think you need to carry 11 types of grease for all the o-rings you have


#362009 How do I avoid my wife murdering me when I come home with two more YS-250Pro...

Posted by bvanant on 09 June 2015 - 11:59 AM


As a happily married man all I can say is find a wife who is into video and make sure that her system is newer than yours.

When you get two new strobes, she gets two new video lights.


#361751 Why do you shoot underwater?

Posted by bvanant on 02 June 2015 - 03:35 PM

My wife just finished a long (for her) documentary of some of the little stuff that lives in the ocean for a kindergarten class. We met the teacher on a trip to the Sea of Cortez and they decided to do a small film suitable for 5 year olds. It turned out great (we will send Steve a copy for the Fin Foundation) and the kids loved it; getting to the young ones early about the cool stuff in the ocean hopefully can get them to think about things in the right way.


#361299 Looking for double flip adapter for wet lenses

Posted by bvanant on 19 May 2015 - 07:48 AM

That is why I suggested using a 77-67 mm step down ring  (I have the Nauticam single ones for both the 67 and 77 ports) and the Saga dual flip adapter. You suggest that it might vignette but that seems unlikely since the lens itself is only 67 mm.
