In Topic: 60mm VS 100mm DOF

24 November 2014 - 12:09 AM

In my blog I made a comparision of 30mm, 50mm and 100mm macro lenses taking the same subject at approx. the same magnification:

You will see that the DOF is the same in all 3 cases (at given F number) but the perspective is completely different. Check especially the relationship with the background (not just the background blur and the field of view, but how the close subject behind the main one looks).
They were taken not underwater but I hope it's helpful.

In Topic: Ikelite DS161 strobe with RX100 in Meikon

I'm not 100% sure but I think the TTL converter of Heinrichsweikamp should work. I guess the sony RX100 uses a similar simple flash protocol as my sony nex-5. I also have a meike housing and I use an ikelite strobe (51S) with their digital adapter. It works well. However, you will need a special cord with one end nikonos, the other end ikelite. You can find information about the converter here:

sigma has 3 more cheap AF prime lenses with excellent quality that missing from the list. Tamron has also 2 zooms (more or less the same) and Samyang has many good quality cheap MF lenses.
