I post 2 images taken consecutively with each other and they are about the same. There is a small area in each shot that it's blurry. It's about 1/3 from top and 1/3 from the right. I thought it's something on the sensor but the 2 areas while similar they are not at exactly the same position in relative to the frame. I can't see no sign of that with images taken before or after those shots. However those 2 were taken with f/29 while others were at f/8.

Smear on the lens?

Dirt on the lens that moved? Ash?

F29 will show dirt etc. on the lens and or the sensor.

Well I guess that is what it is. I can't replicate the problem.

could be a number of things, a loose piece of dust that blew off, a gnat that flew away, something of this nature. I would say if you are no longer having the problem, the question will never be answered and you should go ahead and shoot away and have fun.

Try shooting clear blue sky at large and small aperture, and see what you see.

Focal point. On the first one the people at the very top seem more in focus than the flowers.

upload originals..be easier to see. centered around the area that has stalks but no flower.

I don't think its focus...stuff before and stuff after does not have the smudged look.

A few questions, Are you using a filter of some kind ? Did you clean the lens Did the problem happen with another lens?

If you're working with a dSLR, avoid apertures smaller than f/11 on APS-C or DX format, and smaller than f/16 on full frame or FX format. Diffraction lifts its ugly head at smaller apertures, reducing overall sharpness. It will also highlight any dust on sensors or rear lens elements.

Be sure your sensor is clean, and there is no trash on the rear lens element. It is EXTREMELY important in digital photography to keep the rear of your lens spotless. Change lenses only in still air, to avoid dust, dirt, and debris from invading the camera body and landing on the sensor.

too arrow depth of field shot it at F16 and focus in the center

It's most likely dust or oil on your sensor.... that would show up at the absurdly small aperture of f29 (which is undoubtedly costing you fine detail in your images... search for info about "diffraction" a the Cambridge in Colour website for more info about it).

Small specks and such on sensors are no as likely to show up at more reasonable f8 aperture and larger.

Stuff on or inside lenses almost never shows up in images as a blur like that. In fact, it would have to be something quite large (and very obvious) to cause that much blur in an image.

Stuff on or inside lenses is more likely to cause flare or loss of resolution... but there would need to be a lot of it.

If it's no longer showing up in tiny aperture images, then it was something on the sensor that's fallen off on it's own or been removed by a self-cleaning sensor (if the camera has that feature). Since oil spots can't be removed either way, it must have been something else such as a dust bunny or small piece of light seal foam.
