Here's a suggested design I knocked together in 10 minutes. The camera base plate and example lens plate include provision of 1/4 inch screw fitting for existing tripod heads.

I certainly hope that there is no Canon Propritary QR plate. I can purchase a nice Arca Swiss compatible QR plate for my lenses that lets them balance perfectly for $25. I have several.
No need to pay Canon $500 to upgrade lenses, and another $200 to upgrade each of my tripod heads.
Thats what not to like.
#2 85/1.8 IS - Make it 1.8 IS with faster AF
I keep hearing that the 17-40 is less sharp than the 15-85 - but on a aps-C you will find it sharper, particularly at f5.6 or slower.
Why do you keep repeating that long after I disproved it in my original post? (Hint: follow the link I provided.)
Why should I be overpaying - so that Canon can make more money off me???Correct. Welcome to capitalism.QuoteHow is that a good deal for me, the buyer?It isn't, nor is it intended to be. Welcome to capitalism.
You'll probably be better off with a 600EX RT in the long run.
I was thinking it would just tide me over.
270 has slave only capability off camera and range 28-50mm. It's your money!!
It works for me most of the time. I do have some problems when working in fairly bright environments from time to time. (But then not only my DG 610 Super but also my Canon 430EX has problems) I rarely use the built in flash though, most of the time I slap my Sigma Ringflash on my 7D and use that one for remote firing. That combination appears to be working better, but I am still not 100% satisfied with it. I think it's time to get a radio operated remote controller for my flashes.
while the double Gauss has flaws, it delivers very good performance even in basic designs. And the design here is not a classic double Gauss. The back part is quite different. Also, it's only f2, not very fast for a 50 mm. That plus the liberal use of expensive glass types should do it.
my guess is Canon could produce the same for 2k. it's just a matter of market.
