Birgers and Breathing

[Evin Grant]

It might be easier and cheaper to buy both Birger mounts, but I wouldn't be too excited about switching out those mounts every time I need to go from C-N or N-C.

I don't think it will be as much of an issue between the two Birger mounts, only because there is less tolerance accuracy in these mounts anyway, so as long as they are kept reasonably clean swapping them won't have as much of an efect as the PL which is much more precise.

No collimation, then?

Not every time at least.

someone help me out with my selection here

my current choice would be canon 10-22, then the 24-70, then the 70-200

my issue with the 24-70 is that it doesnt offer IS and the barrel also extends during the zoom. Does this make it a bad choice for the Red camera and ND's?

if one were to buy say 3 canon zooms and 2 primes for the Red (to cover most standard narrative shooting), what would you pick?

would i be better with 16-35, then trying to cover the missing focal gap with maybe a 50mm prime before i jump to the 70-200 zoom?

Same current choice here. I see some exclusions on the upcoming breathing compensation side going with a SLR prime. On the other hand, a 30-35mm will be a normal lens on the 35mm sensor size. I believe the 50mm focal length won't be so used than above or even below a low tele. Framing rocks on the zoom route, more than any other.
