I'm following up my previous post about my new toy, the Tamron 70-200 F2.8 Lens. Since purchasing it almost 2 weeks ago, I've been able to take more than 300 shots with it. Based on this experience I'm going to share some of my thoughts and impressions.
To get this started you need to see what I'm describing. After I set up a quick backdrop and stand I took a couple of shots of the Tamron 70-200mm F2.8 and the Canon 70-200mm F4L. Let's start with the Canon.
Next, my Canon 60D with Tamron 70-200mm F2.8
Finally, here are both cameras equipped with 70-200mm's side by side.
Now lets talk about performance! Under normal lighting conditions, I have to give the nod to the Canon. It seems to lock on faster, especially when the camera is set to AI Servo (contineous autofocus) and I'm tracking/panning quick moving subjects. Since this lens is a little bit smaller and lighter there isn't quite the same fatigue factor as it's larger counterpart.
When the light starts to fade is when the Tamron starts to shine. Having that F2.8 apeture when you need it can be huge. It could be the difference between getting the shot, and just sitting on the bench watching the action. Now I won't lie and say that having F2.8 available solved all of my problems. I still had to kick the ISO up to 1600 to have any chance at a decent shutter speed. And the other problem is this lens doesn't focus as fast as the Canon. There were a couple of times that I missed a shot waiting for the lens to catch up. For my next outing, I'll use another technique to combat this little issue, that being to pick my spot and set the lens to manual focus and have it prefocused and ready. That way I'll just have to worry about my timing with the shutter button, and not hope that the lens has focused.
To sum this post up, I'm still very pleased with my purchase. If I had to pick just one of these 70-200's to keep I'd have to give the nod to the Tamron. Even though it can't focus as fast as the Canon, it's not bad and the picture quality is great (to my eyes). While you can't go wrong with either lens, you should make your decision based on what you are going to do with it.
Until next time, Happy Shooting!
