The 500mm f5.6 pf is on fire in terms of demand/sales. In Canada, you will be lucky to see one if you order it today, by APRIL! When you do get yours, do you mind just posting you got it, I am curious how long it is taking.
I have gotten a very, very small amount of time on one and it is an unbelievable lens. Light, reasonably fast (I can't completely verify this as I haven't had a chance to actually test it in the field), and takes an amazing image. Again, take that with a caveat, using it in a fixed location not of my choosing is not really testing it.... but I was blown away with the small test.
If it wasn't $5K, I would already have one. I need to test it properly first and check the images before I will plop that money down. If there is any consolation, DP Review raves over the lens.

I am not surprised. I have tested the 300mm pf lens and it is stellar! Again, the key feature being extremely light weight and amazingly sharp. I used it covering a Blondie concert and by contract, I can't post it anywhere other than the publication I published it in. If you want to see it, you have to go to FACEBOOK and download the magazine. It is a free download.

If I needed a 300mm, this would be my first choice. I am sure the 500mm will perform equally as good or better.
