400mm plus Stacked tc's

[Roy C]

Trying out the 400mm f5.6 with stacked 1.4 tc's on the 40D today. All shots taken in my garden with a tripod at 800 ISO, f8, Manual focus, my usual P&P
Note the EXIF does not show the extenders because the Canon 1.4 was taped (other tc was a Kenko Pro 1.4).

Still some detail there and quite usable IMHO.

I would be very happy with those results. Thank you for sharing your findings.

Some fine results there Roy, and noticeably no noise at ISO 800 ... a good test!

I'm curious about a comparison against the TC 2x, because magnifications are similar ( 1.96 vs 2)

I also have a 2x tc but for some reason I prefer the IQ from stacked 1.4's.

Hi Roy,
These are excellent photograph's especially with 2 stacked T/c's. May I ask what post shoot processing you did please? Also did you shoot in Jpeg or Raw?
Thanks
Chris

Hi Chris, I always shoot in Raw. Used my normal processing procedure which is:
Tweak exposure and crop the Raw in DPP.
Send to CS2 as a tiff
Downsize for the web
Tweak Highlights/shadows
Sharpen
Noise reduction if required with Noise Ninja (sometimes I use the blur tool instead)
Convert to 8 bits and save as a jpeg.
