I picked up a rather strange Solignor C/D7 teleconverter/Extension tube combination. Not real sure what i'd do with it, but it sounded interesting. Its basically a 2X teleconverter mashed up with an adjustable extension tube.
Turns out i really like it. Sharpness isn't too terrible, But without the 2x glass in there i have to be nearly right on top what i'm taking a picture of. And with a fish tank, it's not really an option.
PP is minimal, slight color correction, and i sharpened up the duncan a little and the sinularia quite a bit more ( i think i went overboard with it) But the xenia is straight color/temperature only.
no external light, just the lights from the tank. shot through the glass. Tank light's are 4x54W t5HO bulbs.
Shot from a tripod (old velbon) I should've disabled SR, but i think the shutter speed was fast enough it didn't make much difference.
please critique, if they suck, tell me they suck, but tell me what i can try to make them better.
edit: for size reference, the green sinularia on the bottom is a little over an inch tall. The Duncan on the top is about 2 inches wide, and each head on the Xenia is roughly 1/2 an inch wide.
