#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.

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

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.



#360720 Need Saga +25 info

Posted by bvanant on 02 May 2015 - 12:41 PM

Based on my calculations, I think you will get 2.5 x magnification. That means that your 4 mm nudi will look like it is 10 mm. The big problem you are starting out with is that your camera doesn't really have macro capabilities. Compared to the CMC, you should see  a tiny (2.5/2.3) effect of about a 9% increase.


#360636 Need Saga +25 info

Posted by bvanant on 29 April 2015 - 04:52 PM

The +25 will indeed work on the camera, but it will not allow him to shoot a 4 mm beasty full frame, the full frame resolution is like 60 mm wide and a + 25 will take that to at best 24 or so, not enough for the original requirement.

Seems remarkably silly to me, what if the bins are full and you can't stow it?


#360383 Need Saga +25 info

Posted by bvanant on 22 April 2015 - 10:21 AM

The CMC should allow you to shoot something 32 mm wide full frame by itself. The problem is that your LX100 is not a very stellar macro shooter. Adding a + 7 to the CMC should get you to something like 30 mm full frame (not a big improvement). The SAGA +25 will get you by itself to something like 30 mm full frame (a bit more than the CMC). Unfortunately the physics of your camera are the fundamental limitation to shooting something that is 4 mm across.



#360343 Need Saga +25 info

Posted by bvanant on 21 April 2015 - 07:23 AM

A lot depends on your focus distance needs. Once you get beyond +15 or so the biggest worries are DOF and can you find the critter. I think the CMC is very well designed (at least for my macro lens) and is quite nice optically. I haven't seen the Saga but always worry about CA with such lenses.


#360273 Ambon with The Underwater Tribe

Posted by bvanant on 19 April 2015 - 11:07 AM

A few weeks ago, my wife and I went to Maluku Divers to do a photo seminar/class with the Underwater Tribe.  Mike Veitch and Luca Vaime led a group of 8, 7 photographers and my wife the videographer ( who has listened to the f/stop, aperture story for the 20th time and keeps asking what an f/stop is) for a week of diving the muck sites of Ambon.  The class was held at Maluku divers and Joe and Emily showed us great hospitality, good food and lots of great diving.  Over the course of the week, we had seminars on basic shooting, advanced techniques, some basic Lightroom classes.  The classroom teaching was very good, Mike is a great teacher and Luca did a fine job on the Lightroom side, but it was in the water that made this class very special.  On each day Mike would take 4 of us and Luca the other 4 and worked hands on with each student during the dive. Unlike almost any other photo class, neither Mike nor Luca took a camera into the water, only a slate. They would help us think about what to shoot and how to shoot it and they did lots of looking at our pictures after they were shot, writing furiously on the slate to change this or that and try again. One thing that we worked on quite a bit is how to use high power LED lighting instead of strobes or as backlighting for shooting larger critters.  After the diving they were available every day for photo critique during the afternoon when we were not diving.  The diving was typical Ambon with several Rhinopias in varying colors, lots of nudibranchs both common and relatively rare, lots of hairy shrimp, one green shrimp (the very tiny one), and tons of other muck critters including the very hard to shoot shrimp that lives in the blue tunicates.  Overall, we had a great trip and want to thank Joe and Emily for running a great operation, and Mike and Luca for helping us all make our pictures better and for making the whole week great fun.
