ISO 12233 crops have been added to the Canon EF 300mm f/2.8 L IS II USM Lens Review
These results are very impressive. The Canon EF 300mm f/2.8 L IS USM Lens
was one of Canon's best lenses. The 300 II bests it - especially with the new extender IIIs attached. As with the 400 II, the lighter weight of this lens over the previous model is very noticeable
- and very welcomed.

ISO 12233 crops from two review lenses have been added to the Canon EF 400mm f/2.8 L IS II USM Lens Review
As expected and similar to what was seen in the Canon EF 400mm f/2.8 L IS USM Lens Review
, the results from this lens are impressive. Less impressive is the much-hyped-by-Canon with-extender-III image quality performance. My Canon EF 400mm f/2.8 L IS USM version I Lens performed at least as well as either of my Canon EF 400mm f/2.8 L IS II USM Lens lenses with extenders mounted.
Lens specifications and measurements are also available for the new 400 II. The lighter weight of this lens over the previous model is very noticeable
- and very welcomed.

Rob asked me to share his Canon EF 8-15mm f/4 L USM Fisheye Lens Cap modifcation with you:
" ... I modified the lens cap of the 8-15 4.0L fisheye lens with two small pieces of Velcro (only the soft part). The result is very satisfying! The lens cap won’t fall of anymore even when one presses one or both clips." (thanks Rob)
Rob modified his original Canon EF 15mm f/2.8 Fisheye Lens
cap in a similar way - using much more velcro for that mod. Canon EF 8-15mm f/4 L USM Fisheye Lens Review

Chuck Westfall (Canon USA) has provided information about the weather sealing found in some pre-officially-sealed lenses.
According to Mr Westfall, "Pre-1999 white EF lenses such as the 200/1.8L, 300/2.8L, 300/4L, 300/4L IS, 400/2.8L, 400/5.6L, 500/4.5L, 600/4L, 35-350/3.5-5.6L, 70-200/2.8L, and 100-400/4.5-5.6L all lack mount gaskets but have moderate dust and moisture resistance for their switches, focusing rings and zoom rings where applicable."
For example, "The EF400mm f/5.6L USM lens was designed before Canon started offering "dust and drip resistant" lenses, so it does not have a mount gasket or a built-in protective filter. However, it does have seals under the switches and the focusing ring, so it is weather-resistant to a point. For best results in wet conditions, I suggest using a clear filter on the front of the lens and covering the lens barrel with a plastic wrap."
"Canon will not retrofit mount gaskets to EF lenses that were not introduced with that feature." I of course had to ask that question.

I added more sample pictures
to the site. These are primarily macro images taken with a variety of lenses.
