I can find many photographs in magazines and manuals taken with the 17-40 f4L, but despite statements that this lens would be tested in April, May, June, and now July, the test results have yet to be published. Any hope?
Also, the EF 400L f5.6 is spoken with affection by birders as perfect for flight shots.
The EF 70- 200 f4L (non IS) lens may not be weather sealed, but is the least expensive way for enthusiasts to acquire a Canon telephoto in this range.
These lenses are on sale at most camera stores and are logical choices for new purchases of equipment working on a budget. Some objective guidance from you as to their quality would be appreciated.
