Most Common Watch Battery Sizes

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!)

I have many filters of different sizes. Most were inherited. This will allow me to utilize them with my various lenses.

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.

I have this and other Kaiser push-on caps in various sizes and I find them handier to use than the more common center-pinch. Seems like I always have trouble getting a grip on the pinch mechanism, or I don't get it seated just right. Especially a problem with very thin-rimmed filters. One note: Don't go by the size of the filter. For example, I have a lens that takes a 77mm� filter but needs the Kaiser 80mm cap. To figure out what mm you need, take a ruler and measure across the lens or filter face at the widest part, then convert to millimeters. These caps aren't to everyone's liking but they work for me!

Great item for charging batteries! It charges AA and AAA sizes, the two most common sizes for me. I've used the batteries in my flash-pack and they seem to be holding up very well. This is my only battery charger, and the batteries are my primary use batteries.

I use the folders for various sizes of pictures so having the folder open horizontally makes for a better and easier display. Most places only offer vertical opening folders. Also, horizontal opening allows me to put a caption sticker visible when open.

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

I bought this holster to hold the common Canon LP-E6 battery pack for 80D camera, and others; fits smaller Olympus batteries as well. It stretches to fit as advertised and mounts handily on the strap. I put it on the right hand side so that the battery does not swing against the rear view screen while shooting vertical. Great product and made in Montana, USA.

I like that this uses common AA rechargeables for easy battery duties. A history of Quantum and Metz gear makes you appreciate that! Because of Covid issues, I haven't had a chance to stretch the legs of this pack in any stressful action but its ease of use gives me confidence that it will serve well.

This excellent tester gives a reliable indication of the remaining capacity of many common battery types. Easy to use and convenient size. It is best to take 2-3 repeated readings to be sure of a reliable result.
