Hello PZners,

As already motioned in several treads I have bought Tamron 70-300 VC EF mount.

It is my first telephoto lens and even more It is my first IS/VC lens.



The new focal length opens the new photographic opportunity.

After few weeks of learning I can make some decent shoots. Not toppers but just good enough for beginner.



But I have one technical problem with this Tamron 70-300 VC.

1. I cannot take pin-sharp images handheld with VC enabled. Even at S= 1/200sec

2. I can make pin-sharp images handheld with VC disabled and speed S=1/200sec



I examine the images the RAW images from my 50d at 100%view.

The images with VC are sharp but I have blur = less than 1 pixel in any direction. It worns me that this is VC blur. The handheld blur at S=1/200 must be only in one direction.



I have several technical questions.

1. Is it normal that I cannot take an even one single image with VC, that is as sharp as image taken at tripod + MLU? - Keep in mind that I can take some pin-sharp images handheld with VC-off.

2. What are the tolerances for motion blur introduced by VC/ IS?

3. In which situation I have to switch off the VC?

- Tripod is one of them.

- what about monopod?

- what about holding the lens with hand against three or wall?

- what about holding the lens on top of your backpack or ground.

…………



4. Do I need to switch the VC at higher shooter speeds e.g S=1/1000sec?





Thanks in advance,

Miro
