    Hi Everyone,

    I have been shooting MF (Hassy system) for some time now and have developed a comfort with the use of EV values when measuring for exposure settings.

    After years of lusting for a larger negative, I have found myself the proud owner of a Linhof Technika V with a Symmar 1:5.6/150 lens. I will spare you all descriptions of my giddiness over this long awaited moment.

    I'm told this lens is part of the original kit the camera was sold as, so it is not a new one.

    I am confused about the shutter speed configuration the lens is mounted in. The speeds are indicated as 1, 1/2, 1/5, 1/10, 1/25, 1/50, 1/100, 1/200, and 1/400. These nine settings do not seem to line up the the 10 settings on my Hasselblad lenses of 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1,250, and 1/500.

    Are the speed settings on this symmar lens typical of LF lenses?

    Can I assume that f16 @ 1/400 on the Linhof is the equivalent EV value of the Hasselblad lens setting of f16@1/250?

    I hope this isn't a stupid question.

    Congrats on the new acquisition. I've been really pleased with my Tech V. I prefer the results from my 8x10" camera, but the Tech V is more versatile and is the most pleasurable to use of any camera I have.

    Shutters of different generations are calibrated in different ways, and then on top of that, your shutter may not be accurate if it hasn't had a CLA in a long time. 1/200 sec. is 1/200 sec, so it's closer to 1/250 sec than 1/400 sec. The EV values are the same no matter what the shutter or format. f:16 at 1/250 is EV 16, so you might think of f:16 at 1/200 as EV 15 2/3.
