Training eye to recognize focal lengths

<p>Hello all, I'm trying to get better at training my eye to recognize different focal lengths. I find that I'm getting better at identifying images that were shot with wide-angle lenses -- the perspective distortion is easy to recognize -- but I'm still having a hard time with "normal" to telephoto ranges. I'm experimenting on my own with subjects and my new 85mm to build up my visual experience, as well as with a friend's 70-200 when it's available. I'm finding that I'm still having a hard time identifying the nuances of compression with telephoto lenses. I really like the look of images as seen in the following links. My guess would be something like a 135 f/2 maybe around f4 or even wider for the first shot and an 85 for the second? I really like the separation and just curious what others think as I continue experimenting. Thanks!<br>

<p>The second one was shot with a Canon 5D Mark III with the 85/1.2 at f1.2. </p>

<p>Make pictures, then look at them. You'll figure it out. (or read metadata, like Jeff did :^)</p>
