I was just wonderring what people think of the Canon EF 70-300mm F/4.5-5.6
DO IS USM Lens.

This is the one with Diffractive Optics which allows it to be less than 10
cm with a zoom range of 70-300.

How does it compare with the rest of the range and are you simply paying for
the convienience factor due to it's size.

Thanks in advance,

John

I'm NOT happy with mine, it has been sent back to Canon 4 times for focus
adjustment (currently waiting to get it back). If you look on Pbase and
search for pictures taken with the same lens, there are some very good ones
so I think I got a dud.

Aside from the focus problem, there are many advantages, but if I had to do
it over again, I would have kept my 75-300 IS with all it's faults but good
but slow focus.

I'm reasonably happy with mine. It has much faster focus and much better IS
than the 75-300 [the 'first' IS]. If it were about $700, I wouldn't hesitate to
recommend it. But with it priced up there with 'L' glass without corresponding
quality, unless you absolutely need the small size and weight [or its more
candid appearance], and you are willing to put up with its 'quirks', I would
carefully consider if you might be better off dealing with a larger, heavier,
and better performing [though more paparazzi looking] 'L' lens.

For some comparisons with other glass [as well as to see what the 'quirks' are],
see:

I wish Canon had used regular glass instead of diffraction plastic (?),
making the lens longer but less expensive with better highlight rendition.

Technology marches on, but seldom gets anywhere.

BTW, I tried contact lenses with the same plastic diffraction grating,
and they were horrible.

I have one but frankly don't use it much any more since I purchased a 70-200
L lens. The knock against the DO is that out of focus areas can appear
foggy and generally less pleasing than the out of focus areas of regular
(non DO) lenses. It can also perform less well when shooting into strong
back light. The great thing about the lens is its small size, for a 300 mm
zoom, and its light weight. For someone who travels a lot and carries a
camera hanging around their neck all day the DO would be a good option. How
many 300 mm lenses could be considered a walking around lens?

Minolta makes one, which has the highest MTF at 300mm of any NN-300 zoom
on Photodo.com: .74 at f/5.6 and .77 at f/8.

I tried it and found it was generally too slow for handholding at 300mm,
but with antishake on the 7D, it would be sweet.
