We recently purchased a second hand Canon 28-70mm f/2.8 L Lens and I tested it out on my 5D Mark II.  I don’t usually blog these kind of techie posts, but when I was looking for some information on this combination of camera and lens, I couldn’t find very much at all. So voila, here I go…

I’ve tried a couple of portrait and macro images so far, as I wanted to see how sharp it was at 70mm with f/2.8, how the blur looked and if the AF could handle catching a baby!

The very top image above was shot with iso 500, 70mm at f/2.8 with 1/125 sec.  The AF on this lens is not as fast as the newer Canon L series lenses, but the USM motor is nice and quiet and it managed with a 7 month old baby, so not bad!  It’s reasonably sharp at the extremes and there is little vignetting (nothing that can’t be sorted in Lightroom). I like the blur (or bokeh, as some prefer to call it) and would consider this a serious contender for portrait photography.  It’s definitely a great all rounder for Weddings and other events.

It also has a macro function, so for details it’s brilliant.  You can go up to 60cm from your subject and get nice sharp close-up shots at f/2.8.

In the past I used a Sigma 24-70mm f/2.8 DG, and I can say that this surpasses it without question.  The Sigma didn’t have a very nice blur (bokeh) and seemed generally ‘harsher’, if that makes sense. The AF wasn’t as speedy and wide shots at 24mm, even at f/8, the edges were badly distorted and unsharp. So that will be my next test with this Canon 28-70mm – some landscape/wide shots, to see how it performs at the other end of the spectrum.
