Hi guys, seeking for your votes for this picture I submitted on a local Wildlife Photo contest...

The votes are to be done via a Facebook account only (if you have one), and are only for a "People's Choice" prize that will also be awarded for the photo that gets the most votes! (so we all know this part is biased and the people with most contacts will probably win that prize). A jury will choose the winner in the "Grand Prize" category.

Close (But Not That Close) Encounter

I was at the bird reserve recently and a chap was using a Nikon P900. This superzoom has a 83X zoom - 24-200mm equiv optic! It utilises a 16MPx, 1 2/3" sensor, same size as the Q. According to the PhotographyBlog review Nikon has incorporated a Dual Detect Optical VR system, which should give (up to) a 5-stop advantage.

I persuaded him to use my SD card and take some sample pics for me to scrutinise. He was using a tripod and snapped these off, I would have liked to look at eg different apertures but felt I was imposing enough. The 5th image is I think utilising the "dynamic fine zoom" digital zoom, as did a couple more even greater magnifiation pics I didn't bother uploading, since effectively it's just in camera digital cropping and there was clear IQ deterioration. I have uploaded these pics onto the forum so the exif is present, but provided links to the full size images so click on the pic to see the 4608x3456 image (~3.5MB).
pic 1 - full sized
pic 2 - full sized
pic 3 - full sized
pic 4 - full sized
pic 5 - full sized

And here is a comparison pic: NX20 (20 MPx apsc) + FD 400mm f4.5. click on the pic for full sized.



Immediate first impressions are of bright, contrasty and really quite sharp images, albeit I would say overprocessed. And one very noticeable and really quite advantageous characteristic: huge depth of field. Particularly at the 400mm equiv focal length you can see the FD400 pic is only sharp mid FoV, while the P900 has all the main group of birds in focus. Not surprising given that the true focal length at around 400mm equiv is ~70mm odd (and F5 in this particular pic).
So, what do you think?

Golden-headed Cisticola in breeding plumage, calling the girls.

Just think, if I had FA* 600 f/4 I could have shot this at 100 ISO...but not handheld :-)

On modern cameras there is no real difference between ISO 100 and 400. This makes for better images because you don't need to carry a tripod and a heavy lens, instead a lighter and darker design that you can shoot handheld and get closer, more stealthy.
Which you did, and got a great shot. ISO 100 doesn't matter here.
When I had the Bigma I shot at ISO 800 and above, just to get the shutter speed up. 1/1600s and above is what I used and only went down to 1/1000 when the light was really bad. Wasn't thinking in ISO but more in shutter speed.

There is a video on this on Youtube, "Paradigm shift in bird photography" or something like that. They explain this a lot better, this is where I got the idea.

Someone I knew who was really an excellent photographer, won many many awards, but not a pro, regularly commented that blur caused by camera/photographer movement was the single most common cause of unsatisfactory IQ. SO up the ISO before attempting to hand-hold at a slower TV.

Well put.
