I think I posted about this on a facebook page while the site image loader was down. This was what I posted:
Pentax SF1 from 1987 showed up this weekend to my door for $17.79. $10 of that was the shipping charge. I wanted this camera because I had the SF10. It was the first SLR camera with a TTL auto flash built into the camera. It, like the SF10 that was the upgrade, also has an auxiliary hot shoe. It’s auto focus with appropriate lenses and also uses all of the K mount lenses in the inventory. The differences from the one year later SF10 are mostly cosmetic. Up and down arrows are replaced in the SF10 with a wheel and the mode controls have become buttons instead of switches. The B-2000 shutter speeds are the same. The auto focus may or may not be faster….but not noticeably so. One thing the SF1 had that the SF10 doesn’t that I like is that there is an adjustment under the view window that adjusts focus for the eye sight of the user. I found the auto flash recovery mode either really slow or else it sometimes didn’t want to work. When it did work, it did what it was supposed to do just fine.
It is pictured with the SF10.
