Corinna, i have been trying to get a shot in with a nice bright suculent green in for ages but it always ends up dark with this flash

. But now i have an excuse to take more pics

, thanks lass.
Hey again dean we have to stop meeting like this, btw when are you getting or have you got the nikon 105? and i am looking forward to seeing what it can do.
slizerama, point taken

and agreed.
zustaparadox, i would really like to get some good quality wide angle macro shots, just for that reason, size dissapears so easily in these telephotos.
flyingseale thats something i would never have thought of... did you mean as in the pic below?
brighteyesphotos, there is not much room for a portrait as the ration changes, unless it was more squared?
Joat, it is an old sigma 105, with a slight back focusing problem (.5mm at 20 cm grrr), but it is nice and sharp despite its age, these were with a 1.4 x tx and 21mm extention. so something like 2:1?
like this flyingseale?
thanks again all
tim
oh btw corinna this was the brightest green of them all, but still couldnt get enough light on the leaves
