One alternative technique to achieve good macro is adding an achromat lens to a short tele or tele-zoom. My 5 dp marumi achromat works quite well on the sel55210 lens at 210 mm. It seems to me that even better than 1:1 can be reached. Few days ago I was waiting for a plumber to fix a leaking tap and he was of course late, so I had a bit of time to kill. I set up my home studio and grabbed few physalis from the kitchen. I think the photos are quite cool. There is a hint of blue color coming from the lens CA enhanced by the add on lens (I guess but I will figure out). Still I like the photos a lot. Lighting was done by a radio triggered external flash with a rim light adapter.
