| Latest Review Posted | Sigma EX DG Macro 24-70mm F2.8
First thing you notice when you use this lens, compared to the cheaper pentax kit and zoom lenses, is how fast it focus'es - very quickly!!
and it delivers pin sharp, deep rich colors and very contrasty photos.
Unfortunately, you sometimes have erratic quality problems with Sigma lenses, and that is the problem I had.
when I first got it, it either took pin sharp images or totally out of focus images, notwithstanding the k10d giving the in-focus beep.
Took mine to be checked out by Sigma and got it back 3 days later with them having to reset the focusing mechanism inside the lens.
since then no problems and works like a dream.
sadly, whilst I wanted the F2.8 for very low light work, the pentax doesn't back it up, and had the lens hunting and hunting until I eventually packed it all away.
So the F2.8 will give you greater low light ability, but you will reach the limits of your camera before you reach the limit of the lens.
great lens - definitely highly recommended, giving it an 8 instead of a 10 due to the initial quality issue. |
