BetterPhoto Q&A
Category: To Be Categorized

BetterPhoto Member		Nikon F90X I want to gift my husband who owns a Nikon F90X, a suitable flash for his camera.I have heard him say that a Sigma ef430 Super flash would be something he'd love to possess. I want to know, before I buy one, if this particular flash will be compatible with his camera.While I was shopping on the net for this flash, it said compatible with Nikon(D) mount. But when I see the specifications for the F90X it seems to have a F mount. I have no clue what a mount might be and would it affect the compatibility of a flash. Please do reply..

John A. Lind		Nisha, I am not a Nikon user, but here is what I know about the lenses and lens mounts, and what I was able to find about ef430 flash compatibility with the F90x: The F90x is also known as the N90s. Found in a couple of FAQ's that the F90x can make full use of the features in the Sigma ef430 Super (made for the Nikon body). If you buy one, make certain it is the model specifically for use on Nikon bodies. About the F90x lens mount: The "D mount" is somewhat a misnomer. Nikon has done much to keep backward compatibility with lenses dating to the F2 from several decades ago. The F90x lens mount is, indeed, an "F" type mount. The "D" refers to newer auto-focus lenses that can provide "distance" information about its focus setting/position back to the camera body when auto-focusing. The F90x is compatible with these "D" type lenses. It's not really a "D" mount lens, it's an "F" mount lens with "D" capability. -- John To love this comment, log in above April 19, 2001
