The link for the Raynox Club is missing. That sounds like a good way to go. Thank you so much for all of your advice. It's really really appreciated

So, I got curious and reverse-stacking. I got out my 50mm and 200mm. I didn't have reversing rings, but i did have stepping rings! They worked well enough with me holding the lens.

Here are the results:

I did not do any post process work just cropped out the black. Pretty sweet!

I have a 18-55mm, 50mm, 200mm, and 70-210mm. The only one that is a new digital lens is the 18-55mm (kit). The others are Pentax SMC-A.

Lowell Goudge - I want to use the extension tubes for macro, and a teleconverter for zooming.

I have a Pentax SMC-A 70-210 and a Pentax SMC-A 200 that I'd like to use for birds; 200mm just doesn't get close enough (right now it's yard birds, and I can get up to 20ft to the bird feeder but how many shots of cow birds and house finches does one really need?!). I live on the Coast. I really want to start getting shots of the Blue Herons, Brown Pelicans, Cormorants, etc.

The Pentax 70-210 is also a macro and I have a Gemini 28-80mm macro. Both are fair. Extension tubes would do the job, I think.

I'm at the point where I'm still experimenting and learning but sub-par lenses aren't going to cut it much longer.

HAVING SAID THAT…there is something about using sub-par lenses and DIY equipment that I'm drawn to. It's because there are so many variables what with light loss, auto focus loss, etc., I'm forced to stop and ask myself, "What went wrong? What could I do to make it better? What if I did this…or this…" and I really enjoy the experimentation and possible artistic results.

Can the loss of light be made up for by adding flash? Rense posted an excellent tutorial on creating a flash diffuser for macro work.

I've decided to go for extension tubes, possible reverse-stacking, and a quality teleconverter to go with my not-so-excellent lenses.

I can't find the Tamron 1.5x teleconverter, but I've found plenty of 1.4x and 2x; I don't know which one will fit a Pentax K10 - one made for Minolta, Nikon, Canon…I googled Pentax 1.7x teleconverter and got something called ProMaster 2x teleconverter. No Pentax 1.7x on Adorama either.

As for getting extension tubes, I've read about the loss of light, but I just can't afford a new macro lens right now, and I don't know mind going all manual; it's the best way to learn IMO. I don't know what sizes to get. I'm not using AF lenses so I don't think I can get the Pentax auto extension tube set K.

I'd love to get into reverse-stacking, but again, I don't know what I need.

Oh, and hello! :o

Hi, I'm Tiffany. I got my first SLR Pentax many years ago. I still have it though now I shoot with my K10. My lens collection is of bits I've been able to get off e-bay, and what came with my camera eons ago. They aren't the best but I've been reading through the forums and I think I can make use of them.

I shoot 100% manual focus. I don't want to depend on auto; I like being in control of my shot; and I want to understand everything about taking a good shot in any condition…except snow. There's no snow in Mississippi :cool:
