I would guess I am not the first to ask this.

I would like a basic beginner book for 13-15 year old grandchildren so they can have some understanding of the fundamentals.

Recommendations??? Many thanks in advance.

Nice but I think they are a bit over saturated with color (especially the red beaks and red legs, and red eye on the first shot). I like the third shot a lot. I just bought that lens on ebay to use on an FX camera and hope it will do well on birds.


The Pukelo (first pic) have red eyes

The reason is because the wave nature of the light:

1) The "F" aperture is the inverse of ratio between the diameter of the hole the light must pass and the focal length.

If we take - for example - a SONY RX100M3, the minimum focal length is 8.8mm and the minimum aperture es F11, so we get a hole diameter of 8.8/11 = 0.8mm

2) If we calculate the Airy disk for that hole and red linght (l=600nm), we get a diffraction resolution of 8 microns.

3) But the pixels pitch of the RX100M3 is 2.41 microns, so the diffraction resolution is THREE pixels, which is very noticeable.

Shouls the manufacturer use even lsmaller apertures, the situation would only worsen.

Bottom line: the minimum aperture is related to physics, not to technology.

YES!!! because of the light factor you have explained, a compact camera with an f stop of f22,on a 5mm lens, this aperture would be about 1/3 of a millimeter,.so what you need to realise is that f22 on a compact is F8,f16 is F5.6,f 4 is F11,f2.8 becomes F8 etc., so at widest aperture all appears sharply in focus.

How can anyone be older than a being that never existed? Wake up and realise reality.

When I bought my first Nikon in 1959, (UK) there seemed only one way of pronouncing the name. Gradually three versions have emerged. Wonder which is the most popular ...Nikon (as in HIT) (as in HIGH) or (as in KNEE). No name calling arguments please. Lets be civil about it.


The name "Nikon" was derived from the camera/microscope manufacturer "Nippon Kogaku", and as the "I" in Japanese has no long pronunciation, the correct term should be "Nick-on" as we Brits call it.
