For lack of noise and ease of use the 150 is better than the 105 (husband has 150 and I have 105!) the drawbacks are you can't get quite as close to subject with 150 - but the image is slightly sharper than 105 - grass and other un-wanteds can get in the way of the 150. The 105 is noisy and can be seen moving up and down and the AF takes split seconds too long for flighty subjects and when you are close enough to take you don't want to raise your hand to manual focus or fine tweak (I get round that by backing up or down a smidgeon!) Results are excellent but the 150 has the edge on very fine detail is what I have found when doing comparisons ......... Like Nick tho I enjoy the stalk with the 105 and feel that I have worked harder to get my pic with it!
