Taking an old friend for a spin
I don't remember getting good results on film, so it seemed a good candidate for my first car boot sale. I have an adapter, so I can use it on the Canon EOS5D. Here is a non-descript photo which however is rather surprising when you look at the quality. This was taken wide open at f4.5. It has been givem normal sharpening as would an in camera jpeg. Beware, if you click on it, the full-size download is about 6mb...
Of course a long lens also excels at narrow DOF, and the background is thrown nicely out of focus here.

Might not be selling it after all.....

Well, if you change your mind again .......
I rather fancy a 600/4.5 on my E-series
(I'm back in Zurich the week after next, too)
Je ne crois pas que tu sois bien parti pour alléger ta vie.... Que veux dire alléger la vie ? Se débarrasser de ce qui est inutile de ce qui ne fait pas plaisir. La photo fait partie des passions de ta vie et surtout tu es un collectionneur qui sait utiliser ce qu'il collectionne : quelle belle qualité de ces deux photos : beaucoup de netteté et en même temps une mise au point bien maitrisée sur ce que tu veux mettre en valeur.
Still LOL ten minutes later :-))))
I'd love to hear about it the day you actually sell some of your gear on e-bay.
