As I mentioned in my previous thread, I picked up one of these from a charity shop. I know that this lens is highly regarded and it was only after I had my roll back from the hour service that I realised HOW nice it really is. The sharpness, colour and contrast are first rate - and the bokeh is smooth too! Now, I am totally new to this lens, but if anyone cares too offer some guidance on its use (what apertures are best and anything to look out for in its useage) I am always appreciative. I attach a photp from my first roll - nothing thrilling, but I am pleased with the lens for sure.
