If cash were no object has anyone any thoughts on the pros and cons of the new Canon EF400mm f4 DO IS USM (1,940g 128 x 232.7mm) against the widely used Canon EF500mm f4.0 L IS USM (3,870g 146 x 387mm)---clearly the former is smaller and lighter but looses some magnification but I have seen some super shots on some Finnish bird photo web sites taken with this lens and of course lots taken with the 500f4---the 400 is also about £500 cheaper than the 500--
