Default Resolution chart shots Sigma 80-400OS and Tamron 90MM.

I made some resolution chart shots just now with the new Sigma 80-400OS for comparison I added 2 from the Tamron 90mm Macro which is according to most one of the best lenses arround.

All shots were made on a not so very stable tripod (but good enough), mirrorlockup and timer of 2 seconds.

ONE PROBLEM, I shot with tungsten light and a little underexposed, I feel rather sick but I promised to made the shots so I did, my exuse however I think the shots will speak for themself, they are all posted in RAW for good comparison.

80mm f5.6 can be found here : www.isfcalibraties.nl/uploads/foto/OS80-56.CRW
