Pentax Kr vs Pentax Kx Autofocus Test

Friday, December 31st, 2010

Die Pentax Kr im Autofocus Test (Safox IX) gegen den Vorgänger Pentax Kx (Safox III). Der kurze Test wurde selbstverständlich nicht wissenschaftlich korrekt durchgeführt, denn die 3te Kamera die filmte musste ebenfalls bedient werden. Testvorgang mit 18-55mm Objektiv, Unterschied ist doch spürbar, der neue Safox IV geht energischer an die Arbeit und ist sich seiner Sache sicherer als der Vorgänger. 1x bedient er sich des grünen Autofocuslichtes (0:50), dadurch ist diese Messung etwas länger.

Sony Alpha SLT-A33 video autofocus example at f/1.4

Friday, December 31st, 2010

Using the centre AF point, the A-33’s phase-detection autofocus automatically glides between subjects. Tested with a 50mm f/1.4 lens. Note: YouTube would not accept the video upload direct from camera, nor after import. Therefore this is 1080i processed in iMovie and output at 720p (the highest output the program allows).

Nikon Autofocus Setting for Action

Monday, March 1st, 2010


This video explains into depth about how to set your camera properly for action shots since there are many sports photographers who aren’t happy with their own products that they paid over $3000 for. This video helps you to get action shots in focus (football, birds, wildlife, portraits, etc.). Enjoy! Note: Nikon D3’s 10 and 11 FPS options will disable autofocusing. This video is an example how to capture action with autofocusing enabled. If you require autofocusing, do not use 10 or 11 FPS options. Update: Sorry for a mistake in the video, use Dynamic Area AF for 3D Tracking, NOT Auto Area. Music: Miserable Lie by The Smiths and Freddie Freeloader by Miles Davis
