What a wonderful article



http://admiringlight.com/blog/full-frame-equivalence-and-why-it-doesnt-matter/

The moment I read this quote I knew I was going to enjoy this article.
I’ve heard many times “Yeah, your 75mm f/1.8 is crap – it’s like a 150mm f/3.6.”  No, it’s not, it’s a 75mm lens with an f/1.8 aperture and a field of view that is the same as a 150mm lens on full frame.

Regular readers will know that I've been banging on about this for years, and Jordan Steele's article is simply the best analysis of this I've read. It explains it and gives an accurate representation of whats going on without the usual misinformation that occurs.

He also writes about one of my long-standing hobby-horses i.e. Why is a 35mm sized sensor "full-frame"? Again regular readers will know that I refuse under pretty much all circumstances to use that misleading and inaccurate term. I do realise however that this is basically spitting into the wind and neither Jordan or myself are going to get rid of this lazy shorthand, but its nice to have a kindred spirit who actually understands whats going on with this "equivalence" and why it DOESN'T MATTER!!

One of his points is why constantly reference to a format you don't use?, and that is the whole point. Working out 35mm equivalents serves no purpose. If you use m4/3 then understanding what you get with a 7mm, 25mm, 75mm lens etc. is far more important than any worthless comparison with 35mm lenses. Know what you use and learn to get the best from it.

This is ESSENTIAL reading for anyone who is interested in reality rather than an internet forum perception of it. It should be compulsory reading for anyone who promotes this myth about a 75mm f/1.8 m4/3 lens being like a 150mm f/3.6 lens on 35mm. Because it isn't, never has been and never will be. People who repeat this innacurate nonsense simply don't understand what is going on and just confuse and misinform people new to photography.

Bravo Jordan.
