The little 40-150 f4 Pro continues to impress.
After a mixed experience with the 35-100, I have stumbled across possibly the nicest and most balanced imaging tool I have ever owned.
I think what I am responding to most, is the balance this lens offers. I have several lenses with some very commendable properties, but few that have a little bit of all of these in one. The colour of the 75-300 or 75 prime, the sharpness of the 300 f4, the form factor of a kit lens and the AF of my 40-150 f2.8.
