It has once again paid off to buy an original lens.
The properties have described previous speakers already sufficiently.
Nevertheless, I want to write something about my experience with the lens:
- The autofocus works thanks to the brightness of the lens very good and fast.
- The viewfinder is bright can thus be the focus, and manually adjust very well..
- The Obtimale aperture for depth of field and sharpness is at 16 to 22nd
- Even with Aperture 2.8, the picture is also very sharp, of course, with very little depth of field.
- Macro shots up to a scale of 1: 1 can also record freehand.
For this you should set a shutter speed of about 1/125 to 1 / 180s.
AF-area mode Single Area or Dynamic.
Autofocus control to C (continuous).
This works, thanks to high-speed sync, with and without flash.
VR on.
- The sharpest shots you get of course still with stand without VR and mirror lock.
- The lens can be also very good in other photographic areas such as portrait, etc. use very well.
- With the ability to use small aperture, objects may exempt from a distance.
- The CA's described by the previous speakers are not stronger than other lenses.
I could this with my shots made so far, established only in extreme shooting situations.
The correction on the PC was easy to perform.
- In the vicinity is reduced to 3.5 maximum aperture. This is not a disadvantage in my eyes.
Including the depth of field is less than 0.1mm (Masssatb 1: 1) and therefore hardly Währe use.
- This lens has a very large range of aperture settings (2.8 -45)
To use these areas, you should know what you're doing.
Despite the excellent characteristics of this lens, this course can not make the laws of optics upside down.
Therefore it is advisable to learn about the effects of aperture settings, such as sharpness, depth of field and diffraction of light at the aperture blades.
Among the keywords, or Obtimale- Conducive aperture, can be found good explanations on the Web.
According to my, so far the experience gained, I think,
I have my money very well spent.
