Hi all i've just sent my sigma 18-50mm Ex macro lens back to the awesome srs microsystems.It had serious front focus issues so i asked for a credit note.
I am now looking for any ideas around these focal lengths maybe the pentax 17-70mm sdm £329 lens or the famous 16-45mm £199 lens.Does anyone use these lenses? and what do they think?

All replies welcome

nicer looking than mine mate what did ya do.

Exposure and composition really Tel.

This one is slightly better but there is still something missing

I put it on my P-pod.It was at f8 1/30sec shutter tried it hand held at first but no chance also there was an annoying little breeze.

This is the most that i could up exposure'anymore and i could see a lot of grain in the background.I know what you mean though it does look a little lifeless.

Is there a tool in cs3 that could correct this?

I've found this to be the case with the sigma 50mm because i am practically touching the flower with my front element.This drastically cuts down the light.

Cheers Tel

I wonder if he gets to take his gear home with him

Nice shot pauly she looks well annoyed

Cheers stefan it was just for my macro flower photography.when you use the 50mm you have to be practically touching the flower like in this image.Because the flowers are so small maybe about the size of your little finger nail.

I want to try and pull away from the flower but still get the 1:1 macro or as near.

I suppose i could do this by pulling away from the flower re-focussing and then crop during processing

Hi iceblinker cheers for the link it states in one of the topics from the link that some macro lenses would be suitable and some not.But the price of these they may be worth it just to get in some practice. http://www.alanwood.net/photography/extension-tubes.html

It also says that a 52mm extension tube performs like a 105mm macro lens when using a 50mm lens.How would this differ from using a x2 teleconverter on a 50mm lens?

Sorry for the lack of knowledge iceblinker Thanks for the help

I like number 1 Dirk. The colours against the grey sky excellent
