Default Colour Explosion - Advice on Focus

Another butterfly from my last trip out. I still seem to be missing the focus point and falling short of where I want to be, or not getting the entire body and head in focus - so all comments and advice will be very welcome from the experts here.

Beautiful shot, the colors in the first shot are so pretty I wouldn't have considered the focus to harm the photo, the second I notice the focus a little more. From my totally rank amatuer perspective it's the f/5.6 aperature that's giving you a small depth of field (when you get that close I think it really amplifies the importance of dof). I would think you'd need to decrease your aperature some to get the right range to get the entire insect in focus. Unfortunately i'm not good enough to know how to do that without effecting the beautiful bokah, and without needing to use a flash in the absence of bright sunlight. With me I tend to experiment till the subject flies off and I miss the shot

I don't see the exif info but I would say to set F stop to 9 or more if you can. my guess is that you have focus set to many points. This brings in the focus to the wings, camera default.
I typically set to center focus which is to a small area in the center.
If it is a macro lens, F9 should be good. I don't have a macro but only pretend I do.

Hi Bil & Lorenww - thanks for having a look and for the tips.

Lorenw - you are right about the focus point, I was using the Canon's 9 focus points - so next time I will change this. I will check the data tonight (I'm at work at the mo) and post it later on.

Thanks once again for the help - Diane

wowww, excelent exposure and good bright colors Dyane

I think Bill hit it on the head when he said stopping the lens down more F5.6 is wide open on some lenses, you have the luxury of F18 (I think) if the light is good enough.... now don't give me all that about camera shake etc... you've done well in the past hand held!

... yeah, spot focus might have helped as well......

Almost, and not bad.

1st,
Exposure Time: 1/125
- a bit low for a focal length of 250mm, ok shake reduction and all that stuff help but ...
F Number: 5.6
- f8 might gives you more dof, but the low shutter speed is causing here more problems.
ISO Speed Ratings: 200
Focal Length: 250

2nd - The backside of the insect and a part of the left wing are in perfect focus, so I guess this is only focussed on the wrong part, the eyes are almost in focus, and a bit of extra sharpening makes this better.
Exposure Time: 1/400
- a lot better in comparison with the first
F Number: 5.6
- same fstop f8 might be better but again the dof wouldn't change that much
ISO Speed Ratings: 400
Focal Length: 200

just mho cheers

Ronny

Hi Rhermans & Square 1 - yes I thought parts of the BFly in 2 were in focus - just the wrong bits. Thanks for all the info, advice and encouragement - means a lot to me and I shall try and put in into practise asap
