Pentax SMC 100-300mm f4.5-5.6

This was a part of the kit with my first Pentax, a lovely MZ-50

I used the lense a lot with that camera, but I just dont seem to get the hang of it with my istDs To dark, blurry...... does anyone here uses this lense with a dslr? Or have any tip?

If it's the SMC-F, it's a decent lens. It would only be "dark" or "blurry" if you underexposed, used too slow of a shutter speed, or focused on the wrong thing. Why don't you show us an example and tell us what settings/mode you used and we can help you out.

I had one with my *ist DS (bought used off of eBay), and I liked that it was all internal focusing and zoom. I sold it to a friend who has been very happy with it as well.

Karl,

I have used this very lens with my *ist DS for almost two years. Most of my shots are taken at 300mm and on a monopod; wide open with shutter speeds that are typically 1/500 or faster. I try to avoid ISO settings higher than 400. Some post processing is done to boost sharpness and contrast.

Below is a link to photos that I have taken with this setup (all except these three were taken with it...american crow, fiery skipper and whitetail deer).

Good luck!

Karl,

Thanks for sharing your examples. You have some challenging lighting for wildlife in these pictures, not to mention the high contrast subject. 1/90 and 1/30 shutter speeds are on the slow side, even with a monopod (which I use for 90 percent of my shots). My hand held shots do need shutter speeds that are 1/500 or faster. In general, I aim to shoot at 1/500 or faster with a monopod; sometimes that means bumping the ISO to 400 or 800.

The good news is, it looks like you are able to get reasonably close to your subjects at 300mm. Get the sun behind you in the first few hours in the morning or last few in the evening and you are likely to get some fine wildlife shots (if you live at a higher latitute, then this may not be applicable advice). Always make sure the eye is in focus. Always make sure that that the lighting is such that you get that sparkle in their eye (this can make or break the shot).

As I stated above, this lens does require that I do some post processing. This lens doesn't compare to many of the longer focal length lenses that you read about in this forum; it's results are relatively soft and low in contrast by comparison. But for the $$$ that it is worth, its not a bad lens. Post processing typically includes a curves or brightness/contrast adjustment, saturation adjustment and sharpening.

Cheers!
