With the modern day new mirrorless cameras like the Fuji X-T2 and the Sony A7-II, there's great fun in finding less-than-usual lenses in abandoned lens mounts, and adapt them to fit the camera of your choice.

There's a lot of adapters available for peanut prices if you want to try something exotic and this article lists a lot of options to get your lens and camera connected.

Don't forget to get a bunch of macro rings to add between camera and lens if that is your thing!

In this article I try to compile a comprehensive guide to adapting lenses to various types and brands of cameras and lens mounts. As you will have found out by now (or you wouldn't be reading this article), most camera manufacturers used their own, proprietary lens mounts to make sure that once a customer (that means you) bought into a system, they'd be hooked forever.

Over time some lens mounts proved to be outdated and they were abandoned and replaced with others. Some manufacturers even went out of business, leaving their lenses orphaned and their users grappling for a new system to buy in to.

Then, enter the time of DSLRs (Digital SLRs) and nowadays the EVIL (Electronic Viewfinder, Interchangeable Lens) mirrorless cameras, and a lot of companies jumped onto the bandwagon of adapting lenses with uncommon mounts to new cameras.

It's a mess out there with the above alone, but then there's also folks who like to cobble up their own 'adapters' and fit even less common lenses to their Fuji, Olympus, Panasonic or Sony EVIL cameras.

Read on and you will find some links to your liking, and even a whole table that lists lens register depths so you can calculate just how much space you need to overcome for that old lens to function on your new camera (or, more likely, how little space you have to cram an adapter into...)

In the near future, I will create a visual catalog of lens mounts, that will contain the most seen lens mounts so you can compare them against your unidentified thrift store find ;-).

Have a modern mirrorless camera and need to find an adapter to fit your lens? Try FotoDiox Pro.

Novoflex have an Adapter Finder on their page: https://www.novoflex.com/index.php

For specialist adapter making, visit http://www.zoerk.com

The epitome of adaptability are the Tamron Adaptall lenses, which had their own adapters for most big brands of the 1970s and 1980s era: http://www.adaptall-2.com shows you the lenses.

A very extensive article by Robert A. Monaghan on what adapters fit what cameras and how to get almost any lens on any other type body: http://web.archive.org/web/20021014232607/http://medfmt.8k.com/bronmounts.html

Get modern day lenses (mostly SLR lenses) on modern day bodies with stock made lens mounts from Leitax.com. For instance, fit your Leica-R lens to a Nikon body with a new rear mount on the lens, no adapter needed!

Want to get into building your own custom adapter? You need to know what distance lenses for different lens mounts register at, i.e. what the distance between lens mount and film or sensor should be. Below is a table that previously was published on a website by mr. J.W. Markerink (fellow Dutchman) but because it went offline I reproduce the table here as I cannot link to it.
