Sigma 70-300 F4-5.6 APO DG Macro

Last weekend I picked up the Sigma 70-300 F4-5.6 APO DG Macro. When I quickly shoot off a few at, and around, the store it felt good and I made the call to buy it, the fact that it came with the UV filter and a Monopod (I am starting from nothing) was also a part of the call.

That evening I banged off some test shots and quickly found a few negitives about the glass - It is a heavy lens, not an easy piece of glass to tote around town on your neck, the Zoom ring is stiff - not bad for me but for my GF it is a little hard to handle.

Also, and this seems to have gone away - was mostly likely my settings - I was getting a number of Blue shots. WB would be perfect in one shot, then I would zoom in a bit and the shot would turn blue as if shot though a blue gel. Seems AWB is not the best way to go with this glass.

Otherwise I am happy with it, the tight zoom means no drift even if looking directly up at a plane or directly down at a blade of glass. The Pentax 55-200 has a little drift, or at least mine does.

Attached are a few shots that tell me to keep the lens, both at 300mm on very overcast days

I've had good all-around experience with this lens. It is long, and somewhat heavy - throw in the grip and flash and you have quite a long, heavy setup.

I've even used it for portraits (at 70-100) and insect macros at 300 with excellent results.

One annoying thing - you can't hold on to the lens anywhere near the front, as focusing spins the sucker around. I tend to do this to stabilize the lens when fully extended. Also, the macro switch can stick, but I've gotten used to making sure the lens focused close, not infinity, to switch out of macro quickly.

I started to get more Blue effect - They think it might be a coating problem, returned in to Henry's tonight and paid the difference to get the Pentax DA 55-300. I am much happier with the IQ, and the much faster (And cleaner) AF. I won't knock Sigma, I think I just got a bad one in the bunch.
