What happened?

Looks like it was in manual focus and not focused on the subject. The dobro is reasonable clear around your knees.

Is it because of the macro filter?


and I've used the auto focus feature.

You had an add on macro filter on front of the lens? That would definitely be it. It was trying to focus about a foot in front of the lens.

I did, So the iso was ok though?

Here is your Exif data, your shutter speed was 1/200 not 1/2000. But that should not have made a difference for this shot. Why would you use a macro filter?

You want to use as low an ISO as possible to get a good shutter speed. So yes.

Ok and I've read on this forum it was a good idea to use a macro filter when you shoot in tv mode and or portret mode.

Boy would I like to see who said that. I think you may have had a brain fart. No filter is best used when shooting in tv or portrait mode. The camera mode has nothing to do with filters or lens. And definitely not a macro filter. They are about the worst thing you could put in front of a lens.

I would agree....drop the macro filter.

So drop the macro filter and the uv filter? or keep the uv filter?

I have a shoot tomorrow and I really need a crutch for shooting indoors in a medium size room with ok lighting.

If it is a quality UV filter you can leave it on. It will do a decent job of protecting the lens.

Shoot in manual if you are used to it. Otherwise, shoot in AV at around f/6.0 with as low an ISO that will keep the shutter speed above 1/125 or so. If the shutter speed is to slow then increase the ISO.

I can do and I'm not used to m mode yet.

I'm surprised you knew what a do-bro was, Thats cool.

The most common and descriptive name for a "macro filter" is "closeup lens". I have a Canon 500D (pricy as hell), and it really limits the maximum focus distance of any lens. On my 24/105 at a FL of 105 mm, the maximum focus distance is about three feet; at 24 mm, it's about eight feet. Obviously neither are anywhere near infinity.

Regarding the UV filter; if it's high quality, then it will seldom cause problems (seldom, not never). The B+W filters are high quality (as are another German brand - Rodenstock - I have two of each).

I also hope you are using the lens hood - always. A little bit of light on a UV filter (particularly a cheap one), or light on the lens, and you'll encounter lens flare.
