Lin Evans Posted June 24, 2014 Report Share Posted June 24, 2014 You may want to also consider the Sigma 18-35 Art lens - more flexible with docking station and generally considered better glass. The 17-40 has a reputation for significant chromatic aberration at full wide angle on a FF sensor.http://www.dxomark.com/Lenses/Compare/Side-by-side/Sigma-18-35mm-F18-DC-HSM-A-Canon-versus-Canon-EF-17-40mm-F4L-USM___1141_0_794_0Best regards,Lin Quote Link to comment Share on other sites More sharing options...
Barry Beckham Posted June 24, 2014 Author Report Share Posted June 24, 2014 Thanks guys, but it has to be a Canon 17-40 because it's for use with an Infra-Red converted Canon 5D camera. Some lenses produce a hot spot when used for I/R and it's difficult, if not impossible to always edit it out. I found that to be the case with the lens I had, which was a 16~35 Canon. I know from information from the Internet and more importantly from a respected photographer friend of mine who has experience of I/R that the 17-40 is good with I/R converted cameras. He uses the same combination of Canon 5D Mk2 and a 17-40 and gets great results and no hotspots..If I bought another type of lens I may go from the frying pan into the fire and still have a hotspot. I already have a 28-135mm lens that is reported as good with I/R. My recent trip away and lots of practical use, sadly confirms the hot spot with the 16-35. (a super lens for visible light photography)I was fortunate that my wife has downsized her camera system very recently, so I actually had two 16-35 lenses, one of which I sold this week. I was offered a 4 year old 17-40mm for $AUS550, but today I picked up a brand new, boxed lens in Brisbane for $737 with full warranty. Some people want just too much for second hand kit and for under $200 saving I felt I may as well buy new.So, the situation is resolved and anyone interested can see my first few I/R images on my Flickr site Quote Link to comment Share on other sites More sharing options...
