In Topic: Question about DS125 current load

25 July 2015 - 02:19 AM

I think that there is no simple answer to how much current the strobe will draw since it it probably a constant voltage charging circuit and the current draw will depend a bit on how depleted the capacitor is after firing.  You could probably instrument something to figure out the current draw but why do you really care?

In Topic: SLR vs. Mirrorless. What is the best camera for macro?

Adam: We are in Bali right now and am shooting the E-M1 and the Oly60 macro lens. To me at least autofocus speed is not a hindrance in any way, seems as fast as my 7D was and while not quite as fast as the 5DIII it seems to me fast enough.

Rob:
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.

Rob:

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.

In Topic: Drowned Inon Z240 - anything worth salvaging?

Well I am guessing it is not Reef saying anything; they sell the H2O tools kit.
