When I get home tonight, I'm going to try to find the shots to show you guys as proof its just a bunk lens. But I believe I may have deleted them in disgust. I hope I still have them to show you guys.
I admit I got a little defensive, but really the underlying tone in most comments toward me was I'm basically an idiot, its user error and I don't know what I'm doing. How could I not get a bit defensive.
I doubt most of you guys even read the post where I described my "real world" style shooting. Its not 100% real world, but its not shooting batteries.
Just to be clear this is exactly what I did, and after so, deemed it to be a bunk lens.
How can you explain how this is user error? Here is EXACTLY what I did:
- Set up a 2 liter bottle of Soda outside on my stoop
- Found a contrasty point to focus on
- Fired off 5 shots in a row on the same exact point at same camera settings (no focus/recompose, I stress, no focus/recompose, the camera didn't move, and I focused on the same exact point on the bottle)
- Change aperature, fired off 5 shots again
- Moved back a few steps, fired off 5 shots again
- changed aperature, fired off 5 shots again.
*Note - shutter speeds were very fast so camer shake were not a factor 1/1600 shutter speeds. Also tripod mounted.
Results: Of each set of 5 shots 2-3 were OOF.
Explain that to me. Explain how this isn't simple focus shift and that its user error.
