Hi Yakim. You're missing hands-on experience. The C 150/3.5N is a nice lens, but not nearly as good as the A 150/2.8. Here's two comparison shots of these lenses, on a 5D with 5 deg tilt, f/8, 1/5 sec, and ISO 400. The first image is the full photo. The two following images compare the C 150/3.5N (top panel) and A 150/2.8 (bottom panel). The first composite image is a 100% crop of the very top left corner, and the second is the same at the top right, with the image for the C shifted slightly in, away from the extreme corner, to match the A 150/2.8 framing.
The C 150/3.5N is less expensive than the A 150/2.8, but the "A" is worth every cent.
