  • I think Olympus has chosen the 20/20 definition for DOF, because it is easier to reach shallow DOF then ;-). This is approximately equivalent to 4000 Dots over the image diagonal and to 0.005mm CoC. ...
  • Ok, thanks, I didn't know that, but have now done some research and math. Yes, 20/20 is normal vision but they most achieve that only with glasses. I used to learn that if you reach 1200 points ...
  • Yes, I did not care about this. I just accepted the selection of defaults that where offered by the calculator and tried what matches. Change the viewing distance by 10% or the shooting distance by ...
  • Ok, I dont have the lens, so I cannot check it. I have however found images of the lens: For example, if the focus distance is infinity, aperture is f22 then the near limit should be a little bit ...
  • Yes I think this. Generally I think DOF calculators are not too accurate. They can use simplified formulas. For my purposes this doesnt matter, I want only a rule of thumb result and comparable ...
  • For rather close distances probably all DOF calculators give unreliable results, because at close distances the lens probably actually has not 17mm but less. Without knowing the lens construction ...
  • Replied in Rating on Amazon
    The total rating on Amazon Germany is positive. However, most written ratings on Amazon Germany are negative especially if in comparison to Sony, Fuji and others. There are 8 german rezensions, ...
  • Ok, thanks. I did not know that they grow so big. We have here only a narrow stream with steep banks, in which the herons can not hunt. They always hunt in the field, I see them often. Often they ...
  • No, probably not, this was larger. He swallows a mouse in a second. He had some work with it.
  • Created photo thread Grey heron and a poor guy.
    What did he get here? A hamster?
  • Missing focus rectangle is not normal. I took a test image, but by heavy camera shake I prevented the camera from finding focus. It confirms focus anyway and takes the shot and displays the focus ...
  • If you have such an image, post the non edited out of camera file for examination.
  • This is what I mean. In situations where it cannot find focus, it can confirm focus and take the shot. This means the green focus confirmation dot inthe viewfinder is green, the beep confirms ...
  • So far I have found it can confirm focus and fire the shot, but clearly nothing is in focus. Happens too often. In these cases however the focus point position is displayed by the camera and by WS. ...
  • So far I found, the focus point is only displayed for out of camera files, jpeg and ORF. The information for the focus is stored in the makernotes, here made visible with ExiftoolGui: Some software ...
  • I would recommend to put the battery into a charger and watch how long it takes to charge to 100%. If this takes 5 minutes only then the display was not so accurate. It is technically very ...
  • The tighter crop is already sharpened wit SharpenAI. The larger crop is only sharpened in DxO, "lens sharpness" set from 1.0 to 1.1. I think the bird has not enough detail for enlarging. Anyway ...
  • Created photo thread Perched Bird in a tree
    Which crop is better? The bird was so far away, (130m) I would not have spotted it had I not observed it approaching.
  • It is not a cause for alarm or surprise, in my opinion. In the past, the batteries were worse and the capacity measurement is also never absolutely accurate, especially since a new battery changes ...
  • Hi, I am not an expert, but I think this is a green tint and this happened because the natural ambient light in this situation had a green tint. I did a white-balance to the fern leaves at the left ...
