Canon EF 28-300mm f/3.5-5.6L IS USM

Review Date: Nov 29, 2010 Recommend? yes | Price paid: Not Indicated | Rating: 10 

 
Pros: a definite universal purposes lens working from macro to landscape; wide-angle to tele-photo; shape image
Cons:
heavy

I need a muilt-purposes len for my trip to a rainforest. Macro ability of the len is also a MUST for me. Wow! The image of moths and damselflies which I got, all are razor sharp. Besides its macro ability, using a PL filter to shoot landscape photos, the tone comes out is also very rich and pleasure. The performance of this len is really out of my expectation. If you do not mind its weight, I highly recommend it; or you need to use it together with monopod as a compromise.

Pros: Razor-sharp image, fast focusing, good contrast
Cons:
White len casing, crummy lens cap, expensive

Razor-sharp image even with the aperture wide-opened. 1.4X works very good on this lens. Fast focusing is performed with or without 1.4X attached on 1-series cameras. A stable tripod and ball-head is a MUST for this type of lens. If you are afforded to buy this lens, you will find it worth every cent you had paid. However, if you are bird-photographer, perhaps the lens is not long enough in some occasions. I never use Canon’s original lens cap. It is very crummy to use on the field. If the lens casing is coated in black or “cammo” color, it can be much harmony to match the nature environment.

 
Canon EF 400mm f/4 DO IS USM

Pros: Handheldable; Sharp image; Acceptable in size and weight; Fast focusing; Solid built;
Cons:
Too expensive; Slightly low-contrast; Crummy lens cover;

I own 500mm f/4 len and 400mm DO lens. After I had used them for a period, I fall in love with the 400mm DO len. It is light enough to hand-hold in the field. Though it is too short for bird-shooting, its portable ability would benefit you in the field to take more good images. Using it with a 1.4X attached, the focusing speed and image quality would not loss. However, the most important thing is that you need always having its len-hood attached. If not, the quality of the images will fall extremely sometimes. If you are able to manage it in a proper way, it is really a good tool for all kinds of nature-photography.
