Hi

I ma using 7D with my trusted 300/2.8 since November and earlier when the first ware was 1.0.7 on my 7D, ised to get crisp images when I used 300/2.8 with it irrespective of whether I used Bare lens or converter attached to it but now 7D is not giving me similar results after upgrading firmweare to 1.1.0.

Yesterday I shoot almost 150 + images and on the LCD most of the images were looking sharp but after transferring to the system, all images were so soft that even after processing, images are still soft.

Can anyone help me finding the solution to this.

Here are two images directly from the DPP without any processing, just resized.

It looks like the lens may be front focusing. I'd suggest doing some test shots under controlled conditions (tripod, good lighting, high contrast target - maybe something like the Lens Align or TeamSpeed's Focus Genie https://photography-on-the.net/forum/showthre​ad.php?t=771158 if available). It could be that for some reason you need to do an autofocus microadjustment.


Some Canon stuff and a little bit of Yongnuo.

Did it reset your "picture style" settings after the firmware update? Check the sharpening settings in DPP and the NR settings as well.

Gotak,

Yes, it did reset and then I reselected it as Standard and sharpening level is 3 and all shots taken are in RAW.

I agree, the second shot looks just plain hazy throughout. I don't think the OP will have much success figuring this out without doing some controlled testing.

I upgraded the firmware when it was released itself and initally I thought that some setting got changed but when even after taking approx. 400+ shots and almost all are identical i.e. Soft, I suspent it is the problem of firmware and not the lens because I tried all shooting modes One Shot, AI Focus and AI Servo and also all metering options but still the results are same.

Tomorrow I'll perform some tests using Invisicord focus test sheets or with some high contrast material.

yeah, the first shot is definitely front focused, unless you wanted the bird's tail in focus. Parts of that picture look sharp.

how were the weather conditions? Was it hazier than usual? With tele lenses a bunch of extra factors come into play and can influence IQ. I'd say there is a bigger problem with contrast in the second image than sharpness (yeah it could be sharper too, but contrast is missing.)

HI

I focussed it on eyes in first image and second as well. The climate was morning golden light conditions when you get maximum / optimal conditions for best images. No clouds nothing. My friend who took images with his 40D and 100-400 are clear and there is no hazyness in his images.

Try to step down a bit, to f 4-8, change focusing to mid point only, check camera settings for sharpness and contrast, factory settings alwasy very soft ( setting around 3... increase sharpness setting to 6-7)
I dont think you are out of focus with your pics, more likely to have wrong settings...
The first pic with the hawk is focused at the back, not the head as it should.

Hope this helps ...

Hi All

Thanks for going thru the images and suggesting solutions. I also performed testing in controlled environment with camera and lens mounted on Tripod but the results were still same.

Today I took my camera to Canon Service Centre and even they also got surprised to see such results from such an advanced Camera.

They tested my lens with their inhose demo body as well and results were extremely sharp, in focus and proper contrast.

Final result that they came to was the culprit is Body and not the Lens and they have asked me to contact tomorrow and by that time they will perform some Focussing/Sharpness setting.

For your information, I was getting such images since I upgraded the firmware to 1.1.0. Will update once I get back my camera.

Hi folks - I know this is an old thread, but I seem to be experiencing the same problem as described by Rakesh, using the exact same equipment. Does anyone know what the outcome/solution was?

The issue resolved by modifying the custom function and making Zone AF and Manual AF Point selection options enabled.

There you go! I learned the hard way you want to be more selective when you do bird photography, it could make or break your shot.
