Review: Sigma 50-150mm f/2,8 APO EX DC OS HSM

April 10th, 2014

After a long time of thinking about it I bought the Sigma 50-150mm f/2.8 APO EX DC OS HSM last week. This is a short review of my experience with it. To make it short: It is one hell of a lens!

Let’s start with the formals. The Sigma 50-150 OS comes with a bag and strap, a tripod collar and a quite large lens hood. The lens weighs 1270 g (without tripod collar, according to the kitchen scales) which is just about 200 g less than it’s full format 70-200 mm f/2.8 siblings from Canon and Sigma.
For an APS-C lens that is quite a lot. However I find it very nice to handhold attached to the 7D with battery grip.

The optical stabilizer works extremely well, much better than the IS of the Canon 300mm/2.8 IS mkI. What can be irritating is the very obvious knocking noise it makes when it turns on or off that is shared with the Canon.

The AF is by far not the fastest I have seen. It is silent, precise and fairly fast but by far not as quick as the Canon 300/2.8 or 85/1.8. It is sufficient for real-world use I would say.

The most outstanding feature about the Sigma 50-150mm f/2.8 OS is definitively it’s optical performance. The sharpness across the frame is simply stunning at all focal lengths and probably leaves lot of prime lenses behind. There is no need to stop down for additional sharpness. CA, LoCA, distortion are all nothing to worry about.  But see for yourself… all files are converted from RAW, brightness adjusted, no additional sharpening

The lens is compatible with both Sigma and Canon teleconverters. I have the Sigma 1.4x APO and Canon 2x II converters and only did a few test shots. As far as I can report the Canon 2x does give even better results compared to the Sigma 1.4.

So, should you also get this lens? Well, if you tend to walk around with a bunch of primes in the 50-150mm range and can get along with a f/2.8 lens then this is the ultimate tool for you. Sports, theater, concerts, travel, weddings, portraits – that is where this lens will shine on your APS-C camera. For me it is definitively a keeper.

A short test of the Sigma 70-200mm f/2.8 EX OS HSM

October 20th, 2010

The boring

I had the opportunity to take some testshots with Sigmas new 70-200mm f/2.8 OS that I wanted to share as well as my thoughts about the lens itself.

First of all I must say that I’m a big fan of some Sigma lenses – but not of Sigma in general. I love the 30mm/1.4 and the 150mm macro but I also found some “lemons” that just didn’t cut it like the 120-300/2.8.

The 70-200 OS looks highly interesting to me because it is the first non-Canon 70-200/2.8 that features an optic stabilizer as well as an ultrasonic AF motor, fits onto the EF mount and still sells for at least 20% less (give or take a few percent).

As I tested it in a shop my findings are just rough but I hope they give you an idea what this lens is like.

The lens

My first impressions were thet the build quality is highly impressive. It simply felt solid an well made unlike the Tamron 70-200/2.8 that I used for some hours a few months ago. the OS system works very good and the AF on the 40D was precise as well as decently fast. My EF 85/1.8 and 300/2.8 are faster but these lenses are widely known to be as fast as it gets.

Optically, I think, the Sigma does a really great job but doesn’t reach the levels of the new Canon 70-200/2.8 IS mkII.

For professionals or people with too much money the Canon still is THE lens to get but if I had to choose between the Canon and the Sigma plus a nice 4-day trip to Rome (or the like) the Canon woldn’t stand a chance.

The pictures

The verdict

Would I like to have this lens? Definitively yes. It’s great in every aspect and would fit my needs.

Do I want it now? No, it still is too expensive at around 1500€ but the price keeps dropping so I will keep my eyes at it.

new test

I have done a test of the Sigma 150mm macro with Sigma 1.4x TC and updated my review of it.

It’s all in German but I the pictures should be understandable to all 😉
