Proof positive that the aging Canon 100-400mm lens can take high quality images.<\/p>\n

Canon introduced the EF100-400mm f\/4.5-5.6L IS USM\u00a0lens in 1998 and the now 16-year-old lens has\u00a0taken some hits in the past for its trombone-style push\/pull zoom mechanism (something I never had an issue with) and its slightly\u00a0less than prime image quality.\u00a0I used this lens\u00a0exclusively while my 500mm prime was in the shop and I was very happy with many of the images I took with it.\u00a0 Following are two examples.<\/p>\n

\u00a01\/2500, f\/8, ISO 500, Canon 7D Mark II, Canon<\/em> EF100-400mm f\/4.5-5.6L IS USM @ 400mm,\u00a0+1.4 tc, not baited, set up or called in
\n<\/strong><\/p>\n

I photographed this Northern Harrier along the Antelope Island causeway 13 days ago with that lens. The\u00a0photo was cropped to exactly 50% of the original image and in my view image quality held up nicely, especially considering the use of the 1.4 teleconverter with\u00a0that lens and the sizeable crop.<\/p>\n

\u00a01\/5000, f\/8, ISO 1000, Canon 7D Mark II, Canon<\/em> EF100-400mm f\/4.5-5.6L IS USM @ 400mm,\u00a0+1.4 tc, canvas added for composition,\u00a0not baited, set up or called in<\/strong><\/p>\n

A day later I photographed this harrier in almost the same spot along the causeway.\u00a0The image is\u00a0nearly full frame with a small amount of canvas added up top.\u00a0 Once again I think the image quality is very good with this lens and attached teleconverter.<\/p>\n

Since these images were taken I’ve purchased the new version of this lens, the EF100-400mm f\/4.5-5.6L IS II USM.\u00a0 I haven’t given the new\u00a0lens much of a workout yet but if the improvement is as much as advertised I will be extremely pleased.<\/p>\n

I apologize for the photo-geekiness of this post but photographers live and die by our lenses and cameras so they’re never far from our minds.<\/p>\n
