Camera focusing systems have a "Focusing brightness range" (Canon parlance), "detection range" (Nikon parlance) specification. This is found in the specifications section in your manual. Your camera is rated for 0-18EV for the center focus point, 1-18EV for the other focus points. Adding an ND filter will reduce the scene brightness below ...
From the question:
Whenever I try to focus, it allows me to only reach to a point where the subjects are only slightly blurry and beyond that it again goes out of focus.
From comments by the OP:
Neither at auto focus nor at manual. I can feel focus alright without filters. I tried in broad daylight both using live view and viewfinder. Its like reading ...
This is quite normal in a film camera. There's nothing to worry about - it's a relatively low-tech LCD display - not like the fancy screen on the back of a modern digital camera. Think how long the tiny battery in a digital watch lasts for. I think you don't need to worry about your batteries being drained.
Page 12 of the manual just says...
Are you getting focus lock? Some cameras won't allow you to take a shot if focus isn't locked. This can happen if the subject is too close, it's moving, or trying to focus on an area lacking contrast. There are settings in the camera's control menus which will allow you to take a shot if focus isn't locked.
I had a similar problem w T6. All button sequences that should have raised the Built in flash did not work (Q button and selections, lighting button...). It reported that the flash is not available while other accessories are attached to the hot shoe.
On the right side of the hot shoe rail, there is a leaf spring (helps hold accessories firmly in ...
When you add ND filter you decrease the amount of light a lot. And for focusing you need fair amount of light and contrast. So the solution is to focus w/o filter, switch to manual focus and then put the filter to the lens.
What you describe is often caused by ribbon cables inside the lens beginning to crack so that continuity along one or more of the channels is lost only when the cable is in certain positions.
Without knowing what aperture settings are selected when the camera is set to Aperture Priority, it's difficult to draw much from the fact that you do not experience ...
Printing a photo at anything over 300 dpi is wasted effort, since the printers can't do it and our eyes can't see it. A print shop machine will automatically resample it smaller first.
A 6000x4000 pixel image is aspect ratio 3:2.
This 3:2 shape will print:
4x6 inches will print at 1000 dpi
8x12 inches will print at 500 dpi
12x18 inches will print at 353 dpi
The 2000D has a max resolution of 6000×4000 pixels, an aspect ratio of 3:2; therefore at 600dpi you can print it at (6000 / 600) × (4000 / 600) = 10 × 6⅔ inches. Saving the photo as JPEG doesn't make a difference to the resolution, but may affect the quality.
