Most Common Watch Battery Size

For the size, it's really bright. Nice that it uses a common AAA.

Most of my caps are the slip-on type that's more common in large-format stuff, but I got these for some of my vintage Nikkors. I use a combination of a custom step up ring from SK Grimes and a B+W filter then I cap them with these caps. These look very slick, and they work well. I've tried some of the cheaper more generic brands, and these Nikon caps have smoother edges, have less wiggle, fit more flush, and have small details like the fact that the pinch flats taper outwards slightly so your fingers don't slip off the caps when you pick them up or remove them that make them so much better to use if you're busy and have things to do. Many vintage rangefinders have cloth shutters, so you can just cover the lenses with this to protect them when you're out and around.

Step-up rings are a common tool for fitting lenses and filters of different sizes. Most any will do, but some are better than others. Good thread fit is essential, but that's usually achieved. What the PRO Sensei rings add is a slight knurl-like grip which can be a help when unscrewing sticky filters. (Hint: don't over tighten them in the first place!)

Most excellent for its size and works well!

Perfect size. Most cords are too long and you have all the excess to deal with.

Most solid and stable power source from a battery with d-tap.

Great Case!!! Perfect size to transport. Easy to load. With a little trick it will fit for one of the most common professional tripod combination: the Sachtler Video 20 plus CF HD ENG legs. Just take off the little plastic distance holder on the lower leg parts. The overall size will be 91,5 cm. Perfect match. No need to order the bigger 6400.

the size is perfect for full frame enlargements of 8x12,that are now common place to have as gifts

I use this bag as a professional/traveling wedding photographer. It's the perfect size as a carry on bag, looks professional, and NOT like a common camera bag. Fits everything perfectly and protects gear snug and compact.

Very nice light for its size. Very bright white and red light that uses common AAA batteries not some harder to find and expensive batteries. I may use it in my deer stand this year with the red light.
