It may be an individual-camera variation, so it’s best to test it out & see for yourself. Some people have reported better results by just doing a simple 10MP or 5MP crop from an original 20MP image in PP compared to in-camera EZ, others the opposite. This can then be combined with IZ or DZ to obtain a theoretical E1920mm maximum focal length – but IQ starts to suffer severely when you do this. At that point, there’s no downsampling going on at all – it’s a direct 1:1 readout of a 3888x2592 (10MP) or 2736x1824 (5MP) cropped area of the sensor. From personal observation of both the FZ1000 and now the FZ2500, what seems to be going on is that once you turn the zoom ring beyond the E480mm optical limit, the camera starts to read and downsample a smaller and smaller area of the sensor, until you hit the maximum limit. Throughout the physical zoom range of the lens, the camera downsamples the original 20MP image from the sensor to the selected smaller size. IZ appears to have a better algorithm for this operation, so it gives better results than DZ.Įxtended Optical Zoom works the other way around: it’s only available when you set the camera to return Medium (10MP) or Small (5MP) JPEG images.

The same process can be performed – often with better results – in Post Processing by cropping an image down to a smaller pixel count, and then having the PP software re-size it back to the original pixel dimensions. As I understand it, IZ and DZ are very similar: they both “upsize” a small-size cropped image in-camera to return something with the same pixel count as an un-manipulated image. It’s important to understand the difference between iZoom (IZ), Digital Zoom (DZ) and Extended Optical Zoom (EZ). Is the IQ acceptable or not? Namely, several FZ1000 users have reported some good results especially with the Extra Optical Zoom.Īny sample of image taken using the upper features would be very welcome. I was wondering whether some of you have already used/tried those camera features related to the zoom usage: Extra Optical Zoom or Intelligent Zoom or combination of both.
