Type A or B

[cthomas]

I just got my MR-14EX flash. And the manual talks about Type-A and Type-B cameras. How can I find out what my cameras are? I have a Canon 20D and a Canon 40D.

Your DSLRs are Type-A.

Your DSLRs are Type-A.

Thanks. How can you tell?

They are very competitive and have a burning desire to get ahead... ;)

LOL. The type B cameras are older than the Elan II film camera with TLL flash technology, like before 1995?

Type A and type B bodies.

As noted above, Canon cameras built before 1995 don’t support E-TTL. With the introduction of E-TTL flash metering, Canon officially divided their camera bodies into two groups - types A (support for E-TTL) and B (support for TTL only).

However there are also subvariants of type A. Specifically, the first generation of type A cameras does not have support for wireless E-TTL flash ratios and modelling flash; the second and third generations do. The third generation adds support for E-TTL II. To confuse matters further, most type A film cameras support legacy TTL flash, but some later type A cameras including all modern EOS digitals do not. Finally there are sometimes subtle variations in E-TTL functionality between one specific camera model and the next, but that obviously goes beyond the scope of simple type A and B categories.
