Canon EOS 1DX: Twilight performance

Some months ago, a blog was written on bird-lens.com to review the Canon EOS 1DX and explain some aspects of dynamic range and noise in the CanonSumpfohreule, EOS 1DX performance.

As mentioned in the blog, some tests in photo laboratories show, that the dynamic range of the Canon EOS 1Dx benefits from having “only” 18 million pixels with a full frame sensor. For this you get a high dynamic range and a better signal / noise ratio. The Canon EOS 1Dx produces images with so little noise, that you can safely use high ISO values.

To give more examples, I show some images shot at dusk at the Laguna de Gallocanta. A Short-eared Owls (Asio flammeus) was hunting over Continue reading Canon EOS 1DX: Twilight performance

Baffin Shackleton Snow Boot, customer review

Baffin Men's Shackleton Snow BootAfter some reviews-blogs had been written in bird-lens.com about photo equipment as the Canon EOS 1 Mark IV or the Canon EOS 1DX and the Canon 400mm f4 DO I think, I write also a short experience review of the Baffin Men’s Shackleton Snow Boot, because I ‘m often asked about my experiences not only with camera staff but also personal equipment which in many cases are as important for successful photo shootings as the photo gear is.

With my Meindl Hiking boots (Meindl Ortler) I have been very satisfied all the time until the beginning of April this year when I spend 4 days photographing Great Grey Owl (Strix nebulosa) in the vicinity of Oulu in Finland. Finding the Great Grey Owl (Strix nebulosa) can be hard stuff, but even harder to prevent loosing her. To walk/ run behind the owl means walking in 1,5 meters of harsh snowcover, sometimes breaking through the icy cover, sometimes not. This in temperatures between -20° and -5°. It did not take a long time and my feet were deeply frozen whatever socks you wrap around them.
Maybe I should clarify, that I am a bird photographer, who is specialized on photographing as many species of birds for scientific purposes as possible. The subjects to shoot brought me to Varanger in Northern Norway in February or to Finland in early April. Now I trip to Norway was scheduled again. End of November for Golden Eagle (Aquila chrysaetos) s. The experience of Finland should not repeat. So I bought a pair at the german Outdoor Shop “Globetrotter” for roughly 300,- €.

After 7 days in use I can Continue reading Baffin Shackleton Snow Boot, customer review

Canon EOS 1DX: some aspects of Dynamic range and Noise

100% crop of Golden Eagle at baitAfter blogging a review of the Canon EOS 1DX some people asked me wether I can subscribe what is written there and wether it is possible to show proof of what is said, that the dynamic range has improved significantly over the Mark IV.

Some tests in photo laboratories show, that Dynamic range of Canon EOS 1DX benefits from having “only” 18 million pixels with a full frame sensor. For this you get a high dynamic range and a better signal / noise ratio. The test showed a total dynamic range of nearly 11 stops at the low ISO settings in a RAW file. At 100 ISO RAW files, they found a usable dynamic range (while taking into account noise) of 7 stops and at a 6400 ISO jpg file still 6 stops.

The sensor of the Canon EOS 1D X use a new feature where there is no space between the pixels, and as much as possible of the incident light is actually converted into signal.  This is new in a professional Canon Continue reading Canon EOS 1DX: some aspects of Dynamic range and Noise

Canon EOS 1 D X: an experience review

Canon EOS-1 D XAfter having written a review about the Canon EOS 1 Mark IV not too long ago, the review for the Canon EOS 1 D X may be a little bit early. But I think, I write only a short review, because I ‘m often asked about my experiences with the 1DX. Mainly from photographers who (still) use the Canon EOS 1 Mark IV.

With the EOS 1 Mark IV I had been very satisfied all the time and – until February this year – I assumed that I would wait for the next professional model and would skip the Canon EOS 1DX. I would not have thought at the time, that I would buy the Canon EOS 1DX. The EOS 1 Mark IV had been the perfect camera for me. However, in Norway I met the famous finnish nature photographer Marcus Varesvuo. I realized that he was shooting with 2 Bodies of the Canon EOS 1DX and he told me that he had sold his two “old” EOS 1 Mark IV because after the purchase of the new professional models he no longer took pictures with the EOS 1 Mark IV . The EOS 1 Mark IV he had originally intended to keep to use the “better” crop factor of 1.3. As he told me, this is of no importance for him anymore. The higher resolution of 18mpix would allow cropping in the final image very well and allow a significant improvement in noise performance recordings with the converters, which is not suitable with the EOS 1 Mark IV.

The first time I photographed with the 1DX myself, I have noticed not only the above mentioned improvements. The autofocus speed, a speed of 12 frames/ sec and the dynamic range were significantly better. After a short expedition for the Great Grey Owl in Continue reading Canon EOS 1 D X: an experience review
