Kenko's flashmeter is an interesting beast, but having toyed with it in the dealer's, it's not a patch on the highly variable and customised functions of the L758.
Speaking of which, read the instructions for the L758; there is no design shortfall regarding the dome being retracted for specific flat-plane work — it's the skill one should have to use it correctly.
