Here's an interesting new lens from Canon: Google translated article (external link). It's a lens for the mirror-less cameras, and it only has a 1.2x magnification (correction from the earlier reported 1:2). So I'm not interested in the lens itself, but in the built in focusing light. Would be great if it shuts off before the shutter opens (like the modeling lights on the MR-14EX II and the MT-24EX). Would also be cool if the light could be activated by double half pressing the shutter like the custom function on the Canon macro flashes (there seems to be a button for the light on the lens). Would be interesting if Canon made built in focusing lights a regular part of their macro lenses though, but I'd really want the ability to turn it on with the shutter and not have to fumble with a button on the lens.

I agree with you that would be great, if the macro photography market were a lot bigger, then we would have had this years ago. Sadly we are a small market.

To me, it's just gimmick. I use a Fenix flashlight (torchlight) as my focusing light.

Interesting idea, but why such a short focal length? The working distance has to be horrible.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

More and more people are getting into macro all the time though.

The down side to doing that Kurt is that the light might add to the exposure depending on the camera settings. That's why I like the lights built into the MT-24EX -they turn off before the shutter opens. They do influence the light meter, but the effect is minimal.

That's my main concern, and that might be why Canon added the lights into the lens. The intent might be for those lights to be the primary light source -horrible for freezing motion.

Doesn't affect the exposure at all with my typical setting of 1/200, F11, ISO200.

Cool. My next project is to build some LEDs with button lithium cells into my diffusers, so I can turn them into focusing lamps.
