Used the bag with me with a SB900 and the pockets of the Retrospective series.
I had some time ago the pocket "Lightning Fast", although supposedly for flashes with the
Designed size of the SB900, the flash without diffuser has only just fit in,
with not really diffuser.
For me absolutely incomprehensible.
Likewise, there were no further compartments for accessories like flash cable / color foils / diffuser / tripod adapter or similar
available.
With the "Strobe Stuff" bag all of these errors have been finally resolved.
The SB900 fits with mounted diffuser without any problems in the pocket
and forward is another compartment with many Einsteckplätzen for accessories.
(At the bottom of the bag is yet another professional present (similar to the original SB900 pocket)
By default the rain cape is housed)
All in all: a flash pocket as usual Thinktank quality which finally also Accessories
can accommodate large and lightning.
Price is likely to be (especially in comparison to some other Modular Bag) but, if you slightly less.
