Help - have i got a problem with my 70-200 f2.8 ??

[Natalie_B]

Ive been noticing pictures like this recently

0.001 sec (1/800)
Aperture: f/5.0
Focal Length: 200 mm

Exposure: 0.001 sec (1/800)
Aperture: f/2.8
Focal Length: 200 mm


See the background, it seems like it has diagonal lines across it ?
Here is another example:

Exposure: 0.001 sec (1/800)
Aperture: f/2.8
Focal Length: 200 mm

It does always seem to be at the longest end - is this normal or do i have a problem ??
Ive also just noticed that in the last 2 pictures the lines go in opposite directions - how very strange?????

Just looks like bokeh to me

yes its bokeh, but its got lines in it ???
Ive just been researching the net and seen that it may be caused by the cheap filter ive been using :bang::bonk:

linky person had same problem. Check out the April 16th post that has the 100-400 with same effect - apparently is may be due to either IS being turned on and a double reflection of sunlight from your filter, or a dodgy filter.

Try shooting without one then the other and see how you get on.

Filter AHhhhh
what filter are you using and why?

I think it could be your filter too, as suggested earlier try a few shots without it. Hope that works for ya.

hhmm, using a UV filte, a Hoya one - to protect the glass ??
I will have to try this weekend without it

For get the filter and keep the hood on it will stop you knocking it, as for UV sensors are not like film for any problems.
