I am sorry I didn't make it clear. This thread was about getting advice on what lenses to get to build a system for my somewhat unusual 13 YO daughter. These are the lenses I have wound up with based upon the advice given and the economics of used lens. The 80/f2.8 was the cheapest, then the 150/f4.0 (from a APUG subscriber) and I forked over a bit more for the 45mm. But what a nice lens.
My last post was a thank you for all that gave advice, something that many do not do on this forum.
