Excellent service, the lense arrived on schedule and came with a free cleaning kit. The lense itself is lovely to use it is very well balanced on my 1000d and has a very smooth action, its fixed at f8 so working exposure is just a matter of playing with the shutter speeds and iso numbers, there is a slight drop in image quality when the 2x converter is attached but to be honest i think that applies to all lenses. the 4 star rating is simply because i feel the depth of field is quite shallow for f8, but this might be the norm for mirror lenses, i havent used one before. all in all i would recommend this lense without any doubt.
