- If you are not a pro (or a photography obsessed amateur!) you probably don't
- need the extra stop. What it gives you is:
-
- 1 - Ability to take pictures earlier or later in the day (nature photographers
- often work at dawn and dusk).
- 2 - Ability to use slower, fine grain film (publications like this)
- 3 - Ability to retain AF operation with a 2x multiplier and even a 1.4x
- multiplier in the example you give above (the 200 at 4.5 probably won't AF
- with a Canon 1.4x).
- 4 - Better ability to throw backgrounds out of focus
- 5 - Better resolution at any given f stop (probably)
- 6 - Ability to use faster shutter speed for moving subjects
- 7 - Ability to use faster shutter speed for hand held shots
- 8 - Tripod mount on lens (I think this is true for the example you quote)
-
- If the lens gets you 1 really good shot that the slower lens would have
- missed, you could well make back the $425.
