There is some interesting points some have bought up re spending,large

amounts on various lenses.All i can say the good optics are like/become

an old friend,have a really good one,and you will have it for life.sometimes one has optics that you feel,well i might let that one go.

Many years ago i bought a Leopold rifle scope,i cant remeber exactly how much i paid,it was a expensive one,but its been lying in storage,
occasionally it comes out,works well,i can put it away and think -i know

that tool does its job well,So to it is with camera lenses these 'L' lens
are like that too,i want to have confidence in the performance of the tool,i do'nt think these lenses are overpriced or over rated,they do
an exemplarary job,some of those black plastic lenses its like looking through the bottom of an old coke bottle.

I did think of buying the F4 version of the said lens,its very very good,and excellent value for money,But i felt that-i would be in the "darn i wish i bought the other one' club.The F2.8 factor is a major reason
for this lens,and i should be able to get some good astronomy pics.

One of the people in this thread has used this lens to discover a new comet!!!well done Terry-i found your article in old telescope magazine.

Thats amazing!!!
