Review on Sigma 150 600Mm 5 6 3 Contemporary Canon by Aquarium Lanter

May 2016 Update: Recent firmware fixes have improved autofocus performance. UPDATE January 2016: I bought the dock and firmware was released that improved the autofocus performance for me! This is a very shiny toy. It took me a while to post this review because at first I wasn't sure if there were any focus issues. After three weeks it becomes clear that it is an operator error and a learning curve. I will post some sample photos. My Camera: The Canon 70D is a cropped sensor camera, although the lens is full frame compatible - not sure how it works with that. little beast. To demonstrate this, all the photos I uploaded were taken by hand. If you're going to use a tripod, you need a real one, not one of the cheap plastic brands. Photo of my camera with this lens (taken from my phone camera) included. This lens works great but you need to keep track of all the settings and remember which ones you have set. For example, there are two types of optical stabilization and you'll need to remember to turn it off when you're on a tripod, otherwise it will mess things up a bit. To speed up focus time you have a switch that can be set to 2.9-10m or 10m-infinity. Autofocus can be fully automatic, fully manual, or automatic with manual override. A lot of my first exploded shots were taken because I installed something in the wrong place. One potentially great thing I haven't gotten to try yet is that you can buy a $60 docking station that lets you write custom and microfocus settings to the lens and update the firmware. This allows you to prioritize motor speed over smoothness, set custom focal length limits for faster focusing when you know the shooting area, and use 16 separate microfocus settings to fine-tune autofocus. 4 distances x 4 focal lengths. I'll let you take a look, although I haven't tried it myself. It says: Sigma 878101 USB Dock Lens Firmware for Canon Lenses (Black) So far this lens has done a great job for me. However, I am NOT A PIXEL SPECIALIST. Photoshop and Lightroom exist for a reason :) If you're that kind of OCD photographer, you'll have to wait for the other person's evaluation. Yes, it's not fully weatherproof like the $2,000 "Sport" model, and yes, it's made of plastic (I think the "S" model is all metal). But it looks pretty well made and durable, and there are plenty of other things I'd rather spend $1,000 more on. Focus and zoom feel very smooth and easy to control. Nice things: They didn't give you a "cent" for extra services. It comes with a nice soft case with strap, lens strap and lens hood. Technically, despite what Sigma said, I was able to use my teleconverter, but regardless of the lighting, the autofocus failed when I did. There's a firm lock at 150mm via a switch, so gravity doesn't force the lens to pop out when it's moving when it's pointing down. A strange thing. As of May 1st, you can't just download the documentation for this thing off the internet. So if you're bad at tracing flyers, you'll have to call Sigma tech support and they'll email you a PDF.
