Who needs a full frame 135 format camera anyhow? A quick look at the new Sigma 18-35 F/1.8 DC HSM...
|Sigma 18-35 F/1.8 DC HSM
Considering also the price of this lens at $899, compared to the full frame equivalent of $2,200 is something that is hard to ignore.
Of course 18-35 is a pretty limited range, but does cover the 'normal' lens range that is very popular with many photographer.
This first look was just a quick trial in the store with their first copy to arrive, and I was very impressed with the image quality and the bokeh or background blur.
The build of the lens is impressive. It's got a solid build, and has a very smooth (but a little stiff) zoom ring. I like the new texture of the outer shell which is a nice soft surface (which I do worry will pick up some scratches easily).
All the shots I took with this camera were wide open at F/1.8 on my EOS SL1 and it was accurate and quick.
I was actually a little surprised that I didn't see the wide aperture effect in the viewfinder, but once I snapped the photo, I certainly was wowed by the results. There were no aberrations that I would expect first on shooting wide open, but more so the fact that this is an F/1.8 zoom lens which should certainly show even more issues at the out of focus areas. I'm very impressed by the performance for sure.
As I write this entry, I can't help but think about the cost of being invested with my full frame 5DmkIII. The matching camera for argument sake would be with a 24-70 F/2.8L II vs a 70D with the Sigma. The 5D with the 24-70 comes in at a whopping $5,638 vs the 70D with the Sigma at $2198 a difference of $3440! Both cameras I'm certain would not make a single lick of difference with my style of shooting (and I'm very critical of image quality).
Sure there are some features that the 5DmkIII has over the 70D and some image quality difference in high ISOs, but is it that much of a difference that it warrants that price? I'm not that certain.
Regardless, this new Sigma is sure to make it even more appealing to APS-C owners giving them additional speed vs an F/2.8 lens for focusing in lower light which becomes a benefit that's hard to turn down.
More time is necessary to really fully appreciate this set-up but for now, consider me impressed by this lens.
