Pentax V is pretty very much a standard to go by. Just make sure you buy the grey one, the brown/tan one has an older style selenium meter (I believe its selenium) I believe and its not as accurate due to requiring adjustment time when changing lighting conditions. Its like how your eyes need time to adjust to bright light after leaving a dark room. If you pull a selenium meter out of a bag in bright daylight and try to use it right away the reading will likely be off slightly. The grey Pentax V uses the updated metering technology and works perfectly. Its a beautiful device. I've had one by my side for years and when it goes I won't hesitate to buy another even if the price goes up significantly.
