Lets look at another area. The B.I.F. (Built In Flash) The "BIF" Spring assembly is to blame for not allowingth flash to charge up and flash. NOTE: Discharge the capacitor FIRST. This is a very easy repair and requires few simple tools to complete. Remove the two micro small screws that hold the BIF cover on. Remove that cover and look along the sides, at ...
If I understand your example correctly, the focal plane changes with color. I think what you show here is axial (longitudinal) chromatic aberration. APO lenses are not necessarily a solution here. Canon does not mark any lenses as such and as far as I know none of their macro lenses are perfectly corrected for axial CA. The lens you have is pretty good. ...
I am getting the same problem. I bought a 100' roll at Henry's last Winter when it was half price. I wonder if they know something we don't. Tried Ilford HP5, Fomapan 400 no problem. Went back to tri-x and the streaks are back. Definitely the film is problematic
The camera lens is a converging lens. Light rays from the subject enters the lens and the lens, due to the shape and density of the glass lens, emerge tracing out a revised path. This path resembles a cone of light. We focus the camera by moving the lens forward or backward. This action adjusts the position of the apex of the cone. We want the apex to just ...
You are seeing chromatic aberration — a prismatic effect which, as you nicely illustrate, reduces sharpness even in black and white photography. A lens which has greater correction for this is called an apochromatic lens — often something like "APO" in the lens name. Note that in lenses for telescopes and microscopes, you'll often also see achromatic ...
I would start by using a different memory card.
You may want to look into "AF-C Priority Selection" (if the camera has that setting) and see if it is set to Focus. http://nps.nikonimaging.com/technical_solutions/d4_tips/autofocus/ https://blog.nikonians.org/digitaldarrell/2011/08/dd-understanding-what-focus-and-release-priorities-do-during-autofocus.html In AF-C, Release Priority it will trigger ...
AF-S on D90 will not activate shutter until it is in focus. This is a good thing. AF-C will activate shutter regardless if in focus yet or not, if that's what you really want. Holding half press a second first is a good plan. The D90 has menu D10 that might be on, which adds about a one second delay after mirror rise, but before shutter activates.
Auto-focus needs some light and a good amount of contrast. If you are missing either it will seek and cause a shutter delay.
The camera simply needed its batteries changed. I also cleared out a bit of blue battery gunk from a previous battery leak. The autofocus seemed much "snappier" when I put changed the batteries, but the shutter still did not fire. This gave me enough confidence that I put a cheap film in and sure enough it is working perfectly (as far as I can tell before ...
With some image stabiliser lenses this is normal. Just like when you hold the trigger half pressed, the IS keeps running. If the IS motors are audible, the noise will come from the lens continuously.
it produces a continuous noise Even in direct contact with my ear, I could not hear any such noise on my unit. Visit a camera repair store familiar with Canon (preferably CPS) and let them have a look. not sure if it's coming from the body or the lens, though I suspect it's the lense You can activate LiveView without a lens attached if you have ...
Viewfinder "vignetting"/"tunnel view" My vote is that the type of screen on the back of the camera is the culprit causing the darker corners of the view. The size of the screen is large and the angle of view of the corners is more oblique than through the centre, which appears brightest. The corners are darker due to increased corner illumination "falloff" ...
Looks like a common case of lens vignetting. Here is a link to help you do some further research on understanding what causes this issue. https://support.nikonusa.com/app/answers/detail/a_id/14467/~/what-is-vignetting%3F
No accepted answer here. I gave my printer to local Epson service. They said they were not able to reproduce my problem, but they "cleaned" my printer. Since then i almost never has this problem repeated.
I own a 550D - If you have been using a different brand camera for years, you MIGHT just be making wrong menu selections using "muscle memory". For instance, video will not record until you press the "Live View" button you will see a red dot appear in top right of LCD. You can't start recording a video just by switching the dial. It may be worth going thru ...
Unless you use the "Save As" dialog it overwrites the original file. In the case of using it is a plugin with an application such as Lightroom, it will overwrite the TIFF or JPEG that LR generates when it exports the image to the plugin.
