  • Fantastic new option. I was really waiting for such a lens. Especially for landscape work it will let my little eos-m shine. I use it mostly to have it with me every day and to complement my 5DIII...

  • Submitted a challenge entry Colour Moon
    Variable mineral composition of the moon leads to tiny colour differences. "Noisefree" white balanced moon shots with increased saturation show: Dark blue: Metal rich (Ti, Fe) basalts Dark magenta: Metal poor basalts Light yellow/orange: Continental highlands, basin ejecta White long stripes, white or light blue patches: recent impact ejecta

    Living close to a National Park in Vienna we see lot's of bats during autumn evenings. Its much harder to catch them with the cam. Here we see a common noctule (Nyctalus noctula).

    In 2009 I had the chance to participate in the launch campaign for the biggest space telescope ever flown, namely Herschel on top of an Ariane 5. We were working to make this happen since 1996 and no one can describe the feelings we had during take-off.

    On the H14 road from Phalaborwa to Mopani (Kruger NP) we saw a dead Impala on a small tree next to the road. After this "alert" we inspected the nearby bushes for the "owner". The result is shown in the pic enclosed!

  • The 24-105 benefits a lot when doing the new lens correction in DPP. Nothing is left to complain about after it. The change in the preview window is really impressive. Give it a try!!!
  • I use the android app https://play.google.com/store/apps/details?id=eu.chainfire.dslrcontroller&hl=de a lot to control my 5DIII and 5DII. It works like a charm and critical manual focusing on my...

  • Replied in 400/5.6 + 1.4x
    I second the 400/5.6 + 1.4x suggestion since this is a very versatile wildlife lens too! Can be an investment for a long time! (again manual focus when using the 1.4x is not problem here!)
  • On a crop 500mm is just perfect to get also the corona! To document the partial phases this is also enough! Lets take a 7D. Its 4.3micron pixel corresponds to 1.8 arcseconds. Keeping in mind all...
