Hi everyone, I've just joined today so please accept my apologies if I've posted this in the wrong place or asked something I shouldn't have.
I recently purchases a secondhand lens: Canon EF 70-300mm 1:4.5-5.6 L IS USM
I noticed that my shots are relatively sharp at close(ish) range, but really far away distant objects are never sharp (mountains, buildings several miles away, the moon etc..).
I'm wondering if the lens has a problem capturing sharp images at a long distance (would you call that infinity?).
To test this, I sat my camera (6d) on a tripod and manually dialled in the settings, switched off IS, and focused on the moon. The image appeared sharp on my camera LCD, but it's not sharp when brought into lightroom.
Other tests I've done are during the day focussing on buildings around 10 miles away, both handheld and on tripod (with IS switched on). I've also tried shooting moving birds, and none of these are sharp (but I accept that might be due to my lack of experience here).
I noticed the focus distance indicator on the lens moves only to the start of the "|______8" indicator, never beyond (unless I manually change it), if that helps,
I'm not sure the best way to add some sample images (if that helps?).
Are there any other better ways to test the lens?
Could I just be expecting too much from my Lens (or camera)?
