I have a large Bronica SQ-Ai set and have some items that are duplicates or not used by me so have decided to lighten the bag a bit. 1. Bronica SQ-Ai Motor drive. This drive fits nicely on the camera and winds the film at a rate of about 2/second. Uses 6 AA batteries and the cameras functions all work off these batteries, saving your other batteries. Since the film is wound and the mirror reset, there is almost no loss of image when shooting, similar to using a DSLR. I've also found that using either this motor drive or the speed grip is preferred when using any finder of 45 or 90 degrees, like the S-prism finder. There's a button next to the on switch that winds your film at the beginning so that you don't have to use the film crank. It doesn't add much weight to the camera except for the weight of the batteries added, the grip is pretty light. All in all a very nice and useful accessory for your SQ-Ai camera. Price $190.00 2. A 2x tele-converter that is automatic, lenses transmit info to and from the camera body so it's just like using the PS or S lenses. Full metering and aperture priorities are maintained with this converter. Mint condition with both caps. Price $190.00 3. Bronica bellows shade for use with all lenses, includes mask for the 200/250mm lenses. Has seen little use, works perfectly. Price $75.00 4.
