Cover, yes, but my comparisons (tripod based) had a Belplasca 
maintaining decent sharpness all the way to the frame edges 
below f/8, while the 7p Realist I have is a bit soft around the 
edges at wider apertures. At f/11 both are as tack sharp as can 
be, no complaints. Call it "Zeiss is nice" syndrome, but 
Belplasca results to me often seem to have just a bit of extra 
"presence".

Try Spicer "cardboard" mounts with the RBT jig precision 
mounting method. Mount cost isn't much more than a dime 
apiece, and the results can be even more precise than straight 
RBTs. I have details of a method that works for me at
