I have been watching the small but growing band of C300 users who are experiencing a form of Chromatic Aberration (CA) that only happens on blown out highlights but not everyone and I must stress this, not everyone including me is experiencing this problem.
The video above is a prime example of footage shot with the C300 and some severe lighting conditions which would have certainly produced CA if this was inherent in all C300s. Note the lenses being used to produce the video above…Zeiss 28mm and 50mm 2.1 CP.2 Lenses…hey presto !!!
It seems we are getting conflicting results depending on how old your Canon lens is, after looking at Alister’s shots Canon UK told me… “These frame grabs are very over exposed and designed to show the limits of 10 year old optics.
The 24-70 f/2.8L was launched in 2002 and the difference in optical performance between this and the replacement announced earlier this year is huge.”
Q2. Why is the CA not as bad using a DSLR
“The new DSLRs have chromatic aberration correction built in to the camera and lens profiles to understand characteristics.”
I have not seen this problem on my Canon C300 and it strikes me that some people seem to be looking for problems with the C300 and like any camera ever produced if you dig deep enough…need I say more, so there you have it as far as Canon is concerned it seems to be the limit of the lens itself depending how old your Canon glass is…interesting !
