Ok, so I am REALLY needing some help here as I have stretched my mind to the limits. My DM has been asking me what I want for Christmas this year and I can't come up with SQUAT. I'm the type that when I find something I want, I buy it then rather than waiting. So right now, the only thing I can come up with is maybe there's something out there for my camera I can tell her to get me. This is where everyone here comes in. If I give a small rundown of what I have, could everyone give me some suggestions as to what I else I could use?
Here's the list:
Pentax K100D/lowepro case
Pentax 18-55mm kit lens
Tamron 70-300mm lens
Pentax 50mm f/1.4 lens
tripod/case
remote shutter release
Photoshop Elements 5.0/reference book
The Moment It Clicks and Understanding Exposure books
Polarizing Filter
So what else would be useful/beneficial/usable?? The only limitation is that I need to keep this around $100, give or take. THAT'S where the problem comes in. In our hobby there's not a lot under that price. Thanks for any help!!!!
