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:

a little bit of everything…

Japanese_Flag

All good things are three!

The japanese website bcnranking.jp tested the Panasonic GF1. Read it in japanese or english (google translation)

Also dc.watch.impresss.jp tested the GF1. Read it in japanese or english (again google translation)

And the latest japanese blog testing the GF1 is it.nikkei.co.jp. Japanese or bad google english translation ;)

——————————

We stay in Japan but this time we show you the Panasonic 7-14mm lens review at trendy.nikkeibp.co.jp. Japanese or english…your choice!

(FT3) Updated-> New Fuji organic sensor?

We already told you about rumors saying Fuji will join the MicroFourThirds system. Now it seems that Fuji is working on a completely new organic sensor. Image-sensor-world.com says that “Potentially, multi-layered organic sensors can over-perform BSI (Bayer Sensor) by a big margin. Their biggest advantage is that the dye absorption could be tuned to have very high QE in each of three colors, crosstalk can be minimized and each pixel location can detect and process all three color signals. Bayer sensors, on the other hand, get only one color per pixel, effectively discarding 2/3 of the incoming signal.

MuTaka also adds “As far as I understood it, Fuji had succeeded in producing a color picture from the organic sensor. Their test sensor was 1/15″ with a 3 micron pixel. The effective image 320*240 pixels. QE is 65%, and with antireflective film surpaces 80%. For a 550nm wave length
Fuji design is not sensitive to IR so doesn’t need IR cut filter.
The main chalenge is stacking the three layers and the electrodes together. Fuji “needs to make the improvement to the nanometer stamping installment
” .

Leica D Vario-Elmar 14-150mm f/3.5-5.6 Asph. OIS – Review

Photozone made a new FourThirds lens review. Now we have the pleasure to see how the Leica D Vario-Elmar 14-150mm f/3.5-5.6 Asph. OIS performs!

And of cours the lens performs very well but I have to say that the lens is not exactly cheap: Panasonic 14-150mm $1,699.95 at amazon.com
