It is enough bitching about the Tönnchen, here are some tips.
Freehand photography, yes funktionniert it.
No LiveView use because there is a stable position almost impossible!
A stable position à la marksmen is advantageous.
All with stability in the camera as is Pentaxianer's happy example in K5 or Km tested also determined for other models possible. When switching on the Pentax detects a foreign lens, enter 500mm and stability makes great job. Times longer than 1/500 are possible, despite its 750mm by Crop.
You need a filter.
UV or Skylight is a must, blurring caused by mirages with telephoto lenses without good optics normal. All uncertainties are not thereby eliminated.
Mirages are greatly removed and the contrast is increased.
-The Einstellungsweg is really short.
-Knackscharf Is different, the computer can never replace it with something aftertreatment sharpness is Amateuermässig useful.
Are PENTAX DA 55-300mm F4-5.8 ED and 500mm 6.3 Walimex pro comparable?
No!
Focal length is not everything, in image quality are in between worlds.
Walimex is processed middlings, the plastic part at the end looks more cheaply.
The picture quality is still better than I thought.
The setting is really very difficult.
Freehand pictures are possible, the ISO setting should be set higher.
Many DSLRs make still more than 800 Asa clean images.
The depth of field is already mathematically not large, visually it seems even less.
Sports photography, you can forget because the setting is too time-consuming.
Nature photography is the terrain for the Tönnchen. Hot air balloons goes. (Think of UV or Skylight filter).
One advantage of the mirror objective is still relatif compact design.
I still have a lens hood is screwed against the Tönnchen then are visually to the pipe, but the scattered light is gone.
-deduction Because Bildqualiät
-deduction Because recently Einstellungsweg
+ Price
+ Front and rear thread for filter screw rear 34mm front 95mm (Lens Hood)
+ Weight despite the focal length passable
+/- Who the "green" button rarely used, eh uses often "hand Focus"
4 stars, the lens has earned.
