Lenses / Canon 200/1.8 and 70-200Ismk2

« on: May 13, 2013, 10:35:35 AM »

I got hold of a Canon 200/1.8 for a quick test and the lens is in a very fine condition, almost as new, the lens is a classic lens , when Hasselblads MTF lab in Gothenburg measured the lens for Lars Kjellberg  and  Photodo / Aktuell Fotografi years back   it was the sharpest 24x36mm   lens ever measured by Hasselblads MTF lab.  Better than the tested lenses from Leitz, Zeiss,Minolta  Nikon etc
One of my best , maybe the best zoom lens I have  is Canon 70-200/2,8isMK2, a favorite lens when I use Canon.
I took some test photos to se how this example of 200/1,8 behaves  and have the "new zoom" as a reference. One main problem with 200/1,8  lens are that there are no spear parts left.
Here is a quick result, first  F 2,8 against 1,8 and also F-4 from both lenses . 200/1,8 to the right
Stunning

Third Party Manufacturers / 1dx and d800 at 12800iso

« on: April 24, 2013, 08:21:52 AM »

For my own curiosity's sake  I tried 1DX and compared it with the D800 at first  12800iso and then 25000iso , I'm surprised  of d800 iso qualities which I tested in Hanoi  and at the  night a few weeks ago.
Here is the church in Lund with have constant light, both cameras exposed equal

At picture 2  I have marked the area with Jesus equal and let auto contrast calculate the  surface
At picture 3 I have marked a area and let auto contrast calculate the surface, here we can se that Nikon are twisting towards red, Nikon does that because of their black point is different than canon

The 1dx is the best camera from canon I have tested regarding  low banding and pattern noise at base iso, that gives at least one more stop to use compare to 5dmk3

Third Party Manufacturers / Dynamic range, high lights information D800 vs 5dmk2

« on: April 03, 2013, 09:37:05 AM »

There have been lot of talking that Canon can bring in high lights better than Nikon, we all know that we can under exposure a D800 several stops and with out any banding and noise as in Canon.

So we take a look. Both cameras meteringsystem gives the motive 1/800 sec f-5.6
This motive are  then exposure the same  from f-2 up to F-16

At f-2 there is no difference between the cameras, none can reproduce the high light information from a over exposed raw file
