comment Sigma 150-500 f/5-6.3 vs Sigma 50-500 f/4-6.3 for birds in flight?
You do lose some sharpness using a teleconverter, but the 300+1.4x combo is sharper than the 100-400 at 400mm, which isn't uncommon with a prime len. The effective result of that combo is about 430mm at F5.6, which is a nice lens, plus you have the 300 if you take it off. the 100-400 is a more flexible combo with a wider range. Like any zoom it softens at the extended range, but it's still quite a good lens. I only retired/sold mine after buying a 70-200 F2.8 that overlaps range with it significantly.

also, a great article on focus modes and customization on the 7d is here: jefflynchdev.wordpress.com/2011/01/12/…

another suggestion: get focus off of the shutter and onto another button (aka "back button focus"), so you can control focus separately from taking the picture. With a bit of practice it becomes second nature to push both buttons when you want tracking of a subject during the shot, but to get the focus locked in and then be able to turn off tracking makes a huge difference at times. see this piece on DPS for info on this, once you get some time working with back button focus, you'll never go back. bit.ly/wpodgl

comment Can you recommend a long cross body strap?
An update on this topic: Black Rapid was given a patent for the sling technology and has evidently let it be known they'll be defending it. Because of that, both the manufacturer of the Luma Loop and the CameraSlingers double camera system have cancelled their products. Luma has a new product that's just hitting the market called the Cinch. I just got a review copy while I'll blog about when I use it. Because of the patent issue, I no longer recommend the blackrapid products and I'm looking to retire mine as soon as I find an alternative.

comment Is there a 3rd-party Canon intervalometer which will drive both a 7D and a Rebel T3i?
So based on research and talking to various photographers, right now, it looks like the Promote is the "best practices" (and rather expensive) unit. I'm currently planning on buying the Phottix (listed above) which seems to have the functionality I want but at a lower price, knowing I might decide to upgrade at some point. It seems to be "good enough" for my needs for now, and should drive either body despite the incompatible plugs (oh, canon, standardize. seriously).

comment What's the best number of shots to combine to produce an HDR photo?
thanks, @Andrew Heath. Yeah, I dropped my flickr account. Those images aren't currently online, but I flagged this into my Todo file to figure out.

more research shows the Phottix to be another (and much less expensive) option: outdoorphotogear.com/store/…
