Sigma 28-70mm f/2.8 EX DF lens

Thought I'd post up a few test shots I took during "World Pentax Day".
Nothing too spectular really.

I had read in many places that it can suffer from yellow casting and also is very soft wide open. I have found when using AF it can produce some softer wide-open images .... but when taking time or using MF I find I can overcome it. So really it comes down to a slight AF inaccuracy at f/2.8

When stopped down though ... this disappears.

A big thanks for SupremeMoFo here for looking after this lens as I purchased it off him. I have been enjoying it thoroughly.

One thing though ... it's fairly hefty ... especially with the Sigma EF 530 DG Super flash mounted as well.

Here's a few of the test shots from last night at work.

Here's my other new arrival ... rare as hens teeth this TC (this is one of the softer images wide-open).
