I am looking at getting one and would like some feedback, ------------- James: I'm very pleased with the MF-28. I purchased it primarily for the between frames imprint function. There is a list of what can be printed between and in frame below. The only other function provided (which should be a standard featuer ON the F5) is Freeze Focus (Focus Priority). This allows you to put the lens in manual focus, hold the shutter release down, then when the subject comes into focus, the shutter releases. This comes in handy for those trying to do hand held macro work!!! As far as cosmetics go, get ready to adjust to back on the camera. The F5 still fits comfortably in your hand, so don't worry about comfort and handling. If can snap a digital pic of the back on the camera. Let me know if you would like the pic. It's a little pricey, but very nice to have!! Below is funtion list of the MF-28: 1. DATA IMPRINT FUNCTION Allows you to imprint data in-frame, between frames, or BOTH. Data that can be imprinted in-frame: Year/Month/Day Month/Day/Year Day/Month/Year Day/Hour/Minute Hour/Minute/Second Frame Count Sequence Number Fixed Number Data that can be imprinted between frames: Year/Month/Day/Hour/Minute/Second Year/Month/Day/Hour/up to eight characters Month/Day/Hour/Minute/up to eight characters Day/Hour/Minute/Second/up to eight characters Caption up to 22 characters Frame Count Shutter speed/Aperture Compensation degree for Auto Exposure Bracketing Caption up to 18 characters/Year 2. INTERVAL TIMER FUNCTION Lets you take a specified number of shots at specified intervals for a specified number of shootings. 3. LONG TIME EXPOSURE FUNCTION Lets you set exposure duration up to 999 hours, minutes, or seconds. 4. FREEZE FOCUS (FOCUS PRIORITY) FUNCTION Lets you perform Freeze Focus operation. 5. AUTO EXPOSURE BRACKETING FUNCTION Lets you shoot up to nine continuous frames, each with a different exposure. Center value is selectable. Hope this helps, Mike
