Check KEH online, I just got a Pentax 45-85 FA hood for $21 in EX condition. If none are available, keep checking, they seem to get a lot of gear turn over. I used a generic rubber hood before this, and wasn't that happy with it. At one point it fell off with a nice filter attached - recovered unharmed, but only because a good samaritan chased me down.

I've had some great success with Hasselblad CF -> Pentax 645 adapter made by Fotodiox. It works well with CF/CFi/CFE/F/FE lenses. For lenses with leaf shutters, set them to use focal plane shutter. I have tried quite a few lenses from this lineup on the 645D. The ones I keep coming back to are: 180mm CF f/4, 110mm FE f/2, and the 40mm CFE IF f/4. The 120mm makro-planar f/4 is also very nice, but so is the Pentax 120mm macro, which is cheaper, easier to use and goes 1:1. The great news is that a lot of these Hasselblad lenses can be rented at very attractive rates, especially over the weekend. There is no electronic communication with the 645D, so the cheaper CF & F lenses are a better deal than the CFE & FE versions. The image quality differences between CF and CFi might be too subtle to warrent the extra cost - I haven't had a chance to do any tests. For 67 lenses (also using a Fotodiox adapter), the 55mm f/4 modern version is sweet (possibly my most used lens on the 645D) and the 67 300mm ED-IF f/4 * is very sharp w/ great color but vibrations and DOF must be well controlled.

Hi, I too was a bit surprised (coming from another camera) that the 645D was, by default, changing aperture during M mode bracketing. For landscape exposure blending this was baffling because the camera was changing the depth of field on me (same issue Ryan mentions above), and I certaintly didn't want that. However, these defaults can be changed in the menu settings. Actually, the 645D is very flexible for bracketing, and works very well when combined with mirror lock up and 2s drive delay. So you can take bracketed exposures on a tripod with one press, and not need a remote cable release if 2s delay is good enough for your needs.
Here are my settings:
- Mirror lock-up UP (rotate dial 'M.UP' near right side of lens mount)
- In DRIVE menu, I select Self-Timer 2s. The camera will flip the mirror up, then wait 2s for vibrations to settle, then take the shot(s).
- In MENU page C1, I have "7. One-Push Bracketing" set to "2. On. Pressing shutter release once takes specified number of bracketed shots"
- In MENU page C5, I have "29. Green Button in TAv & M modes" set to "2. Tv Shift. Camera sets shutter speed relative to the selected aperture for proper exposure."
Its the last setting (C5) that switches how bracketing is done. It also changes the behavior of the green button, but in a way that I find more natural, especially when using third-party lens adapters. With those, I set the aperture manually on the lens, then press the green button to have the camera automatically set shutter speed. From here (optional) you can manually bump shutter speed +/- with the finger dial.
I do wish there was a way to have M.UP dial automatically enable/disable 2s delay. That would be one more menu setting (DRIVE menu) I could avoid when switching from hand-held shooting to being on a tripod.
