I'm eyeing a refurb of the 150mm F2.8 EX DG OS HSM APO Macro lens this morning. It looks like it is a darn good lens from what I've read of the reviews. It would give me added distance for skiddish insects, it looks like it may be a better lens than the Sigma 105mm EX DG OS HSM I have now (which I really like) and possibly the Canon 135mm(?).

Here is a link to some photos a guy posted on Amazon comparing the 150mm macro to the Canon 135mm f/2 (which I have and love).

Only downside I have read is the bokeh isn't great with the 150mm macro but still ok. Plus, my huge main concern would be how fast it auto focuses if I were to use it on of course my running dogs and insects before they take off. As we all know, the 135mm focuses pretty darn fast!

So my thoughts ...
Sell my beloved 105mm macro and my beloved 135mm and just have the Sigma 150mm macro refurb (if it isn't sold) to replace the two and still have $ left over!

Any input on my latest brainstorm would be greatly appreciated since I would have to act fast! Especially thoughts on the comparison photos the guy posted on amazon ...could the 150mm really be that much better!?
