My 5X7" BlackJacket arrived today and I just had a chance to try it out with the camera on the tripod. Wow, this is really a great product, much lighter and easier to use than than that other brand hood. And it is indeed possible to remove and insert the dark slides with the hood over the camera so there would be no need to go to the 8X10 model for this feature, at least with my camera it won't be necessary. You need to adjust the hood bit to the side to do this but I found it to be no problem.
Now, here is another thought. Why not just adapt the design a bit so that the BlackJacket could also be used as a changing bag?
OK, I gotta have a BlackJacket for my 7X17" and 12X20" Canhams. Let me know about pricing and availibility. I figure you could do a one size fits all for the 12X20", 8X20" and 7X17" banquet cameras.
But congratulations, this is really one outstanding dark cloth. And thanks, Francesco, for the recommendation.
