E-P2 vs 5D vs MP-9 and Leica 25mm versus Nokton.

Share


ThePhoBlographer (Click here) posted a high ISO noise test comparison between the Olympus E-P2, Canon 5D MkII and Leica M9-P. The 5D is the best camera but according to the reviewer “the EP2 and M9-P are almost neck in neck. “. But what is a bit surprising me is the following statement: “Both cameras use CCD sensors from Kodak, so this is a very interesting test to see.“???

A forum user at Mobile01 (Click here) posted some image comparison between the Leica and Nokton 25mm lenses. Gogole translation doesn’t work so I will tell you what to do. Click on the green links of the first post to open the images!

GH2 is faster than the E-P3 on Panasonic lenses (and older Olympus lenses)

Russian Olympus forum user “kkn” measured AF speed of some micro four thirds cameras. The text is in russian but the good news one of our russian readers (Thanks!) told us how he made those measurements: “In two words: he records camera’s sounds during AF process and measures the time between button half press’ click sound and AF confirmation sound. He does not measure time for exposure (obvious) and time needed to clean up the matrix. He does not also measure time needed to close diaphragm (which can be quite slow, for example, Panny 20mm f/1.7 has very slow diaphragm and much quicker on its open (f/1.7) than, say, f/4). He does 10 or more measurements for each lens using same light conditions, but different subject’s distances and provided average values.

As you can see the Panasonic GH2 still focus faster than the new Olympus E-P3 when using Panasonic or the “older” Olympus lenses. The only time the E-P3 is faster is when using the new 14-42mm IIR kit lens.

I don’t know how accurate the test is. That test goes against the common perception reviewers had about the E_P3 being much(!) faster than any other m43 camera in good light conditions. Take it with a grain of salt!

Camera vs the Human Eye. And do digital sensors lose effectiveness after some time?

Why can’t I just point my camera at what I’m seeing and record that?” If you are looking for the answer you can find it here at Cambridgeincolor.com. It’s really one of the best articles I have read recently. There are a couple of very interesting facts:

1) Angle of view

Although the human eye has a focal length of approximately 22 mm, this is misleading because (i) the back of our eyes are curved, (ii) the periphery of our visual field contains progressively less detail than the center, and (iii) the scene we perceive is the combined result of both eyes.” and “Our central angle of view — around 40-60° — is what most impacts our perception. Subjectively, this would correspond with the angle over which you could recall objects without moving your eyes. Incidentally, this is close to a 50 mm “normal” focal length lens on a full frame camera

2) Resolution and detail

I guess most of us thought our eye would have more “Megapixels” than a camera. Surprisingly the answer is NO! Cambridgeincolor says: “A single glance by our eyes is therefore only capable of perceiving detail comparable to a 5-15 megapixel camera (depending on one’s eyesight). However, our mind doesn’t actually remember images pixel by pixel; it instead records memorable textures, color and contrast on an image by image basis.”

3) Sensivity and Dynamic Range

Dynamic range* is one area where the eye is often seen as having a huge advantage. If we were to consider situations where our pupil opens and closes for different brightness regions, then yes, our eyes far surpass the capabilities of a single camera image (and can have a range exceeding 24 f-stops). However, in such situations our eye is dynamically adjusting like a video camera, so this arguably isn’t a fair comparison.

Conclusion:Overall, most of the advantages of our visual system stem from the fact that our mind is able to intelligently interpret the information from our eyes, whereas with a camera, all we have is the raw image. Even so, current digital cameras fare surprisingly well, and surpass our own eyes for several visual capabilities. The real winner is the photographer who is able to intelligently assemble multiple camera images — thereby surpassing even our own mental image.

And there is another interesting article at Quesabesde (Click here to read the google english translation) The question is: “Do digital sensors lose effectiveness after some time?” The answer is No!….But not a 100% No :)
