Another picture of what we call a mountain marmot, it would stay at distance to see what we were up to. It was off season no other people around.

They're pretty chilled as they are used to people being around. Location was Richmond Park which is a major in-city park in London.

Liking the marmot photo  :-+

I have played with those megazooms. A problem with the concept of focal length equivalence is that you get the field of view equivalence, but you don't get the resolution equivalence. In practical terms, there is plenty of pixels on this bird but not that many feathers. I have no practical experience with big boy telephoto lenses to offer, but going by maths alone I suppose a true APS-C or hi-res FF equivalent would be 1000~1500mm plus appropriate digital zoom to narrow the angle of view.

Not in terms of price and portability, though ;)
Kjelt:
Yes I never said it could keep up with the big boys  :)
Esp. With flying birds this camera can not hold up.
The focus is also extremely difficult in the bird picture you see that the focus is more on the green tipends than the bird. It was just an example standig hand shot.

Even with a Z9 and 600mm with 2x objective weighing what 12kgs and costing what my car is worth, I would not been able to take this shot that fast because the bird sat there for three seconds, I would have also need a tripod setup  ;)

So no discussion, quality AF etc. is nowhere near the big boys toys but for my application it is more a low weight scope replacement I can carry with me on hikes without braking my back, with the foto as souvenir.
magic:
You can also do macro with megazooms, here with Raynox DCR-250 +8D close-up lens.

Verdict: somewhat usable, but there are better pics out there, even ignoring the out-of-focus corners due to tilt. Not much texture on the thing and the sharp edges of metal traces must be a heroic work of in-camera sharpening ;)

The die was some 1.5x1.5mm.

I don't think this is quite true - you can turn on/off the settings for lens corrections in the camera, but the image data in the raw file doesn't actually get corrected in-camera.  If you load the raw file into nikon software, the corrections will be applied then based on the camera settings, but you can still turn the corrections on/off in the viewer.  Well most of them, it doesn't seem to want to let you turn off the distortion correction - probably so you can't see how bad it really is sometimes.  But if you load the raw into a third-party software you can see that the actual image data in the file is completely uncorrected, to the extent that other raw viewers need to apply their own lens corrections to approximate the results from the nikon software.
