this is with remote, stabilization off and tripod why?
Curious is all. Most people do not consider using them with the point and shoot zooms. They can make a difference. I have a Canon SX60HS and it is very helpful with it. I did notice on mine when you get into that digital zoom range I get that watercolor effect in the images. I think it has more to do with the small sensor size. However, if I stayed out of that digital zoom range, the image quality was very good when stabalized or even hand held.
i work only with optical zoom
Why in 30x I can not focus on long distances and in 29x or 28 x y es?
I would take a similar picture with the lens zoomed half way out on an object a similar distance. Then on computer enlarge to check focus. Also is there a filter on the end of your lens?
I have not understood your question?
Can you explain again tour proposal?
It's just a focus test. Take your lens and set on tripod. And at several zoom settings take pictures of the same scene. I would also do it at different aperture settings as well. So maybe 16 pictures in all. 4 different zoom lengths and 4 different aperture settings. Then take the pictures to the computer and zoom in on screne to check the quality of the pictures.
Even the best of lenses, especially zooms, will have "areas" where it's not as sharp as others. Most likely at either end of the zoom range and at largest aperture.
the problem that from a certain distance the lens does not focus on 720mm 30x ... so the samples will be within the distance that if focus ...
An inexpensivly made filter will also affect a lens. Was wondering if a filter was on the lens during the poor IQ shots. And if there was a filter. What quaity is it?
