Hi,
I recently bought a new Tokina 11-16 MKII - and I just wanted to ensure myself - if these issues I have are normal for this lens:
Camera: Nikon D7100
First of all - I am not using Live view at all (old habits) - so all the photographs are being taken through viewfinder
1. the picture is more sharp on f 2.8 on 11mm then on 16mm
2. Sometimes while focusing on the object which has solid color (especialy when the object located more than 4 metres away) the lens is loosing the focal length (sometimes it can set up on 1.2 metres focal length and sometimes on infinity)
3. It has got small BF (like 2 cm) on 16mm
Basically it accuracy in focusing with viewfinder is not always 100% - I would say around 70%
(all other lenses made by Nikon have 100% accuracy finding proper focal length)
I am overreacting or this lens is just like that? (I red few reviews of this lens - and some says, that this is normal, and some says that this lens is super sharp (that is true - even on 2.8 is quite sharp)
