Thanks for the thoughts guys. The stuff fits into two bags that aren't too bad to carry. My normal method for dealing with the qty of equipment is to shift to a single bag for a particular walk/subject.
I did see a suitable backpack for all the stuff @ Midwest the other day, but it's $300+. No way.
The K30/2.8 just came in today so I'm looking forward to using it. Last week was my first time out with the A35/2. Results were very nice. The M75-150 was also pretty respectable. I'd highly recommend their acquisition. (I got them both bundled together on eBay 2 weeks ago for $reasonable.) The M75-150 is FS as the A100/2.8 covers it well and I really need something a little longer, in the 300-500 range.
