Hi All,
I am looking for a nice 150 mm lens, and looking at auction listings. I noticed that some of the descriptions for the Nikkor W 150 mm 1:5.6 lenses have an "S" in a circle at the end of the...

From experience I believe the opening for the ground glass for the 45D is about 2.5 millimeters shorter than others. I purchased a Yanke ground glass/fresnel/grid set from China on the auction site...

Just take your time and do all the lugs including the side ones. Once that is done, you'll love the SP-445.

Had same problem. You need to sand down the flash in the groove with 600 grit paper. It’s in the instructions.

Hi All,

Thanks everyone for the advice. Yes, I've been to the Ace Hardware store and Home Depot, but I really didn't know what to look for. I will go back to Ace and look at their 4-40 screws. I have the...

Hi All,
Thanks for the advice. I will take out one of the screws this weekend and take a macro photo of it, and also take some measurements with a micrometer. For those of you that don't know, and...

Hi All,
I am looking for a source for the thick headed machine screw that acts as a pivot for the slider levers for the standards. Not sure if I described it correctly, but included is a photo. I...
