Under sports shooting conditions, an image stabilizer seems unnecessary and very expensive. Thus the selections immediately narrow to Canon EF 70-200mm f/2.8L USM Macro, Sigma 70-200mm f/2.8 DG HSM II Macro, Tamron AF 70-200mm f/2.8 Di LD IF Macro, and Tokina AT-X 828 AF Pro 80-200mm f/2.8 SD. Tokina is no longer in production and no useful review can be found thus given up. Canon's price tag is high and image quality is not necessarily better than Tamron and Sigma (www.dpreview.com). The options are clear. I ordered both the Sigma and Tamron and tested both of them on a Canon EOS 7D back to back.
In a short summary, the I compared the performance of Sigma 70-200mm f/2.8 DG HSM II Macro and Tamron AF 70-200mm f/2.8 Di LD IF Macro, two lenses popular among budget photography enthusiasts, using a Canon EOS 7D camera back to back in rigorous lab tests and in real life shots under identical conditions. The Tamron lens shows superb image quality when focused and the copy of the Sigma lens is a total disappointment showing problems in its optical design and quality control. To conclude:

- The Tamron copy shows superb image quality, incredibly sharp and low chromatic aberration, but has a tendency to misfocus for low contrast object under low lighting condition
- The Sigma copy shows nothing good: significant front focus beyond the camera can compensate, intolerably high chromatic aberration and very soft focus, and totally unusable.

I documented the finding in a detailed report with a lot of test pictures. You can download the report from here:

In the end, I returned the Sigma and kept the Tamron, which did not diappoint me later on.

Hi,
I would really like to start my own photography business.
I already have a Canon 60D camera and 85mm f/1.8 USM lens. I would really appreciated any advice that anyone could offer me on what other lens would compliment the lens I already have and the required lighting that I would need to buy for a small studio specialising in baby portraits.
Thank you

Meaning can jsmug list everything on an album level. Like if you have an album called cars, then inside it you have the Pontiac, Buick, etc galleries.

It seems like this component is gallery specific. Is it any way to set up different categories and displaying how my set up is on smug now on my Joomla site? Take a look here:

I'm sorta new to Joomla as well. Maybe I'm looking at how this works wrong. Sorry if thats the case

Hi There,

Still here (just)

Always planned to make jsmug 1.5 native, but no confirmed plans or ETA at present, sorry.

Can I ask what you mean about the difference between album and gallery.  To me they mean the same thing.

Jeff

Anybody Out There?

This is what I have at present, when I got on my other PC I will post some more.

can you share with us some of the great pictures you took of the kingfishers?

its not bad to use photoshop on photographs but when you see a photograph with a no editing. that requires real talent.
