EF-M 28mm f/3.5 Macro IS STM
« on: August 05, 2016, 09:12:47 AM »
My new EF-M 28mm Macro lens arrived this week, a fun little toy.  Focus on my M2 seems reasonably fast (a bit faster than the 22/2).  Just grabbed a few shots last night at 1:1.

The integrated lights are a great idea, although it's a bit annoying that while there are two separate continuous LED lights, the power can't be varied independently – the single button cycles them together through high, low and off.  FWIW, at 1:1 distance the high setting delivers about 4 EV of light, and the low setting is ~2/3 EV dimmer.

The shots below are:

1. Ambient lighting (2700 K LED), 30 s, f/11, ISO 400 (WB set to Tungsten during RAW conversion)
2. Lens LED on high, 1.6 s, f/11, ISO 400 (WB set to Flash during RAW conversion)
3. Lens LED on low, 5 s, f/11, ISO 400 (WB set to Flash during RAW conversion)

For shot #3, I diffused the LED on the right side of the lens with a handheld piece of translucent paper.  There's no good way this type of shot could have been done handheld in that ambient lighting, but with the built-in lights and assuming a ~3-stop IS, I'd only have needed two more stops of light to handhold (e.g. ISO 1600, which will yield decent results with DxO Prime NR). 

I'll get out and do some 'real' shooting with the lens soon...
EOS 1D X, EOS M2, lots of lenses
