I've been looking for a film camera for a while now to do really long exposure astrophotography. My D70s just generates too much noise for usable ultra-long exposures.
A guy that works with me has a N90s(F90x in Europe) in very good condition for a very good price, with the MB-26 data back.
I know this camera doesn't have a mirror lock-up function (not really vital for long exposures) nor the ability to change viewfinders.
Does anyone out their have an idea whether this camera would be decent to use for astrophotography, or any experience with the battery life over long exposures? |

If you're worried about battery life on a camera for long exposures, I'd go with and F3 or F4. F3 is mechanical, so you don't really need to worry about the battery after the shutter is open. The F4 has a mirror lockup feature, and I'm pretty sure I read that after an exposure of x-length it "powers down" so to speak and conserves battery; However, I don't really think battery will ever really play an issue unless you're leaving it on all night and covering the lens during the day so that it'll still be on the next night or something crazy.
I have an F4s and I highly recommend it. It's a BEAST of a camera, and it has the controls of a classic manual SLR with the automation in focus and exposure modes of newer cameras. It's great. I love shooting Neopan 100 and Velvia on it. If you shop around, you can find a nice deal on them-- I got mine for $175 via Craigslist but I've seen them even at $150. Also, it has a removable viewfinder and data back support. |
