I am contemplating buying this lens and although I’ve read a few reviews on POTN, I would still appreciated a little more information relative to this potential purchase.
About me: In the 80’s I had a Canon AE-1 (motor wind, flash, a Canon 50 and Vivitar 100-200), which was mostly used to photograph motor sport events and for holiday snaps. I later moved to an Olympus Camedia (0.85mpx), a Concord compact (5mpx) and latterly a Fuji Finepix S9600 (9mpx) bridge camera. The Fuji reawakened my interest in photography where I got a little more creative. I bought the 550d last Christmas and I find I am hooked with a new hobby.
Subject matter is still motor sport, but I do enjoy landscape, night sky and wildlife with some automotive product (components).
When I was looking to buy my first DSLR, I (like I guess many did) looked primarily at body functions; video was one of the features that drew me to the 550D (and the price). I looked at a 60D, but considered it too expensive for my needs. It is only now, that I think I was perhaps a little too hasty in selecting the kit 17-55 and the Tamron 70-300 lenses (although the latter is adequate for the time being).
I’m considering the Sigma 17-70mm f2.8-4 DC OS for the following reasons:
- It will replace the 18-55 and give a little more reach before switching the Tamron
- Being f2.8-4 will hopefully allow me to be a little more creative
- I am hoping it has a greater IQ than the Canon kit lens.
- Price seems reasonable
I did briefly consider the Canon Canon EF-S 17-85mm f/4-5.6 IS USM at a similar price, that would give me a little overlap in reach, but thought a 2.8-4 would be better than the 4-5.6 would suit me better. Similarly, I considered the Sigma 24-70mm f2.8 EX DG HSM to be out of my price bracket.
There are a few threads here regarding filters, specifically putting cheap CPLand ND’s in front of good glass. If I’m going to spend the money on a proper lens, I really ought to buy some proper filters:
Previously, I bought a cheap ebay CPL and a set of cheap ND’s (2,4 & 8) from ebay – they have proved to me that I can use them creatively, so thought I better get some proper ones for the new lens.
Your comments on my thinking/choice would be appreciated along with any experience of this lens, especially if you replaced your kit with this one.
Oh, also, am I right in thinking that the front of this lens does not rotate on focus and zoom (I'm thinking of the rotation when using a CPL). Also, is this a twist zoom rather than a pull/push? - I question this last item as the description makes reference to a "zoom lock".
