Trying my hand at some macro pictures...

Taken with the Pentax 100m f4 macro lens. If anyone knows (if possible) how to record the f stop with this lens I'm willing to listen.

Thought i'd throw some pictures out there.

Already have learned that you really need to stop down a macro lens to get and DOF. Also Tripods are good. I really need to become better friend with mine.









Thanks for looking.

Fred

Nice shots. I know what you mean about the DoF issue - more is better (sometimes).

As for the tripod, I have a couple, both of which are still gathering dust, as most places I go are too crowded to use one. Plus I like the freedom to move around. My best friend has been my monpod. When going in close, I tend to use the external flash to ensure sharp results.

Nice pics! I've got the same lens, and I think it's just wonderful. It's said that the FA f2.8 is even better, but how can anything be better than this?

The DOF issue can be a bit of a problem, but at times it works for you and not against you. This is not a good picture, but still I think it's bit of fun:

No, when using manual lenses (Screwmount, K or M) no information about focal length or f-stop is passed on to the body, and therefore not to the exif. Only shutter speed (since the shutter is in the body) is there. With A-lenses the f-stop but not the focal length is registred.

It's easy to register these though, with some low-tech gear. What you need is a pen and a piece of paper. Thedifficulty lies infinding that piece of paper when you pp the pictures at home.:-)

fred,
you're going to love this lens. i had an affair with one for about 28years until i got my 1:1 macro. i still miss it's light weight.. it's a superb lens. most macro shots i did with it were at f16. i have many examples.
for your f-stop problem there is no way to record it automatically. you can however do it after the fact by using this program. unfortunately it will only do one image at a time. d/l reveal

cheers,
roy
