I certainly have a lot to learn about this lens, and look forward to your comments:

Fozzie - great to see the first shot up from the 150mm macro.

My only comments on this would be focus point and DOF. I noticed that you have a fairly wide open aperture - try reducing it.

Take a subject and do a whole series of shots focussing on the one point and then using a whole range of apertures so that you can visually see the results.

This will give you an idea of DOF for a particular subject. Remember that when you go to 1:1 you have bugger all DOF so you need to know what you want to focus on.

Keep em coming mate

Chris

Good work fozz. I am very keen on getting a dedicated macro lens, and this adds another level of interest.

Looking forward to seeing more of your macro work over the coming weeks/months

cheers

Thank you for your comments. This is all new to me and I actually sat down last night as read the lens manual.

Unfortunatley when I did the shot, gusty wind and inexperienced macro photographer, not a good mix. But I will carry on regardless.

Lens build is good and AF fast.

Cheerio,
fozzie

Just a quick question: I haven't been able to easily find the info on Sigma's lense naming.

As I understand it DG means for digital?
EX is to do with Low dispersion glass? (EDIT: Found that it refers to "Excellence", considered to be pro type lense)
APO I'm not sure?
HSM refers to the AF motors (silent/quiet)?

Basically I'm trying to understand the difference between:
Sigma 105mm Macro EX DG f2.8 AU$510.00
Sigma 150mm APO Macro F2.8 EX DG HSM AU$900.00
other than the focal length.

Pip my old lad - sorry for that a bit of Dickens

Well the major difference is the extra 45mm plus HSM is a hypersonic motor - fast and quite

pippin, go here...

http://www.sigma-photo.com/Html/lenses.htm

for all info relating to the sigma abbreviations, and info about the lenses.

There are also a couple of newer lenses under NEWS that don't appear in the main sections (thanks fozzie for that info)

Yeah, I found the link but thanks.

Thanks for the news page tip, was wondering why I couldn't see the 150mm Macro.

Nice first shot Fozzie. I agree with what Chris said. It's difficult shooting macro in windy conditions though. Plus with the apertures needed to get decent DOF a tripod is often needed. When I use my macro lens I only ever use manual focus.

Can't wait to see more as i'm interested to see how this lens performs.
