Tyson doesn't like the lens because:

1) Autofocus is poor in low light, which reduces the lens's usefulness shooting portraits.

--- he claims he was having trouble shooting his son with the equivalent of 10 60W bulbs 5ft away. Give me a break, 600W 5ft away? Yes the focus slows in low light but maybe once you get to the equivalent of 2 60w bulbs in a large bedroom. Its a macro lens, if you are expecting fast focus then you don't understand how macro lenses work. With focus limiter in use under the lighting he describes I find the 60mm really close in speed to the 45mm.

I have to admit that I don't find the 60mm "really close in speed to the 45" for low-light autofocusing.

I was photographing some friends inside the other night and having a hell of a job with the 60mm because it was hunting wildly. I switched to the 45mm and immediately noticed the improvement in autofocus speed. It was a bit embarrassing, really, because one of the friends I was photographing had just bought an E-M5 and I was trying to show off the 60mm - and it really failed.

2) Focus by wire is "not optimal" for macro work.

---- true but totally usable once you adjust to it

3) Resolution seems to deteriorate more at high ISO more than it does with some other lenses.

- - - not sure if thats even technically possible?

What do you guys think?

He is not describing what I would call low light, that's why I said under the conditions he was describing.... Namely 600W of lighting only 5ft away. As the light drops the difference in speed grows between the 60 and 45, which isn't surprising based on the fact the 45mm lets 1.5 stops more light get to the sensor for focusing.

Agree in both respects. One might add that not only AF speed (speed of focus movement) but also the ability of a lens to lock focus is also merely a function of light intake (max aperture) under otherwise identical circumstances (same AF target, same light level, same lens microcontrast, same body). So the 60/2.8 can be expected to start hunting before the 45/1.8 does when the going gets rough but still do significantly better than a kit zoom at the long end.
