Donated lens from pixmedic sample.

Here is a shot from a lens pixmedic donated. 135 f/2.8 used on a pentax k1000

I was testing various things and learned that flash sync speed is different on film than digital. So most of the roll did not come out right. I took two shots of the tree testing it out in low light, and this is a quick scan of the negative.

More practice to come as I need lots of it with film stuff. lol

Looks pretty good! You should have it all figured out for the next roll.

Now that I know to keep shutter speed at 60 or lower, lol. I can redo mock studio shots and not have only a sliver of the image showing. lolol

The flash sync speed depends on the camera. My Pentax ME and ME Super have flash sync speeds of 1/100 and 1/125. The K1000 has mechanically-controlled shutters (the ME and ME Super have electronically-controlled shutters), so I can see why the sync speed might be slower on it (there's probably more to it than that, but I'm no expert in shutter design!). I think it really depends on how fast the shutters can move across the film plane; on the K1000 I would guess that the shutters can't completely open or close much faster than 1/60 of a second.

Also, I think the K1000 had a horizontal-running shutter, where the M series has vertical shutters that are common today. So the K1000 shutter needed to open further (the width of the film, not the height).

I dunno, boss just said I need to use 1/60 to sync with flash, I was using 1/200 or 250, I got the right 1/4 of the shot only exposed using that speed. Actually, doing math I must have used 250 since I only got a 1/4 of it exposed...quick math tells me I was 4x too fast...so 60x4 being 240....puts it pretty close to teh 250 I was using.

We've been too busy lately for real "lessons", so when I do something wrong she tells me why and what to do next time.

I learn better dealing with screw ups anyway.
