(part 1) Back from Australia-China: unfair E-P1 versus Mamiya7 comparison.

Dear readers!

I am finally back from my journey. I had a job to do in Australia and China. First of all I would like to thank all Australian and Chinese people I met during those two months. The whole trip was an incredible experience and I never had any difficulty at all working in both countries. People were extremely friendly and I came back to Europe with many many many good memories. Thanks!

Tevidon Zeiss 25mm f/1.4 on the E-P1

tevidon

Just found some test photos of the Tevidon Zeiss 25mm f/1.4. It is a vera tiny lens and the focal lenght and aperture are very promising.
So I searched for some image samples and I found some here:

Fits perfectly on the but the bokeh is not very nice. Let me know if you find more about that lens!

I found some lenses of this lenses on ebay:

Focus Numerique posts a G1/GH1/GF1/E-P1 ISO comparison table!

Visit the Focus Numerique website to see the ISO comparison table. The website is written in french but you don’t really need to know the language. Just look the pictures!

http://www.focus-numerique.com/test-97/panasonic-g1-test-bruit-electronique-12.html

For those who do not speak french here you have the google translation in english:

“After some tests with a non-permanent housing, we invite you to explore new photos taken in the classic conditions of our tests. GF1 The Panasonic does not offer several levels of noise reduction and we just played with the correction of brightness to see its influence on the management of electronic noise at high sensitivities. As usual, you can view images in full definition by clicking on the thumbnails and download the raw file format (RW2).

The Panasonic is equipped with the same 12 MP sensor as the Panasonic G1. However, the chip image processing is a Venus Engine HD (identical to that of GH1 this time).
As on the previous model, the electronic noise is well managed up to ISO 800, the sheep is certainly noticeable at ISO 200 and 100% on screen, but it is virtually indistinguishable on an HDTV monitor 1080 in full screen or an A4. The grain is, logically, more and more prevalent with the increase in sensitivity, but images remain many details until ISO 800 and prints are perfectly usable even in A3 +. We note, however, the presence of flat colors in the uniform areas (already observed at ISO 400 on screen at 100%).
Beyond ISO 800, the colored bands are more visible, but at ISO 1600 the images were still holding. At ISO 3200 things are a bit more complicated: the grain is coarser and more colorful (always in the form of strips). The details are somewhat diluted, but with a bit of post scanning (with raw files in particular), it is possible to have more than respectable results on a A3 +.
With the brightness correction enabled, the presence of electronic noise is more pronounced in standard mode, the pixels are more colorful and visible images at 1600 ISO less convincing. In high mode, the sheep is much more visible and details deteriorated to 1600 and especially ISO 3200. Use sparingly so … “

(UPDATED) New GF1 and E-P1 reviews and tests!

Panasonic GF1 on street review …..ohhh! what kind of language is that? Thai! :)

First GF1 unboxing images http://www.jacobheftmann.com/news/archives/8878

Imaging resource just posted some Panasonic GF1 image samples (with ISO comparisons).

And they also finished their E-P1 review: “It’s clear from the image analysis of our test shots that the Olympus E-P1 has more to its appeal than good looks and a fine form...”

Panasonic Lumix GF1 – studio test photos can be seen at fotopolis.pl

zone-10.com reviews the E-P1

Mark (the owner of which43.com) posted many GF1 versus E-P1 comparisons.

For example take a look at the shutter noise comparison (first set of noises is the GF1, second is the E-P1)

He says “the GF1 is slightly louder and I find the noise more intrusive.” You can download the mp3 audio at http://which43.com/?attachment_id=87

Autofocus test are available here (part one) and here (part two)

Good job Mark! ;)

First Olympus E-P1 autofocus test with firmware 1.1

Gearlog made an autofocus test with the new firmware 1.1. Their conclusion is that there are no remarkable improvements. Focus Numerique also made a test (french). English google translation is available here . Their conclusion: “In AF-C mode, the autofocus does seem more responsive and especially in video mode, the problem of pumping and loss of focus was not resolved“

A more simple test has been made by Lucifer himself ;)
