Hi Tan,

Another exhibit of your talent! The colour of #2 JS is fantastic, but my favorites are the pictures of thelittle heron! The clarity/sharpness and compositionis unsurpassed! How far where you from the bird? Did you use an added-on telephotolens?

Thanks for sharing,

Emmanuel
Thanks Emmanuel!

I did not add any lens (all are macro close ups you see....) and this fella was abt 4m away? not too sure, but I was at x12, and the bird was still not full frame. This is abt 40-60% crop.

Very nice, sharp and detailed Heron.It's the most unsual Heron picture I can remember seeing. Number 5 is my favorite, it just seems to have more to look at and the pose can't be beat. As always, your macro shots are outstanding. Singapore has some strange spiders.

Don
Thanks Don!

I suppose the curve in the neck on #5 adds to the dynamism of it.

Singapore does have some interesting spiders....I think they occur all here around south east asia. Thankfully, most are not poisonous!

Wow I am impressed, you have "set the bar" pretty high with those pictures. When you say diffused flash, what do you mean...donna
Thanks donna!

Diffuse flash is like using the omnibounce diffuser.

Here are the pics of my flash...

Well Tan, looking at Sven's tables I am not sure anymore of my statement.

Looking at the last tables in his page
http://people.freenet.de/seemolf/achromats.html#start

At F/8 on FZ5:0

+4,5 @ 4x has 8 mm DOF
+ 8 @ 4x has 2,7mm DOF

+4,5 @ 12x has 1,2mm DOF
+ 8 @ 12x has 0,4mm DOF

There is more than 7 times more DOF from 4x to 12x.
Considering that 6-7x Zoom is less than the middle between 4 and 12x, we might have something like this:

+4,5 @ 12 x has 1,2mm DOF
+ 8 @ 6,5x has 2 mm DOF
(5 times +8 diopter's DOF at 12x, nearly twice than +4,5's DOF at 12x).

Thus double DOF (which heavily depends on focal provided by zooming, rather than diopter, IMO), but I am not so sure of this (might be less or even more, for these are generally logarithmic curves).
I don't know the exact formula to calculate DOF extension and these are only possible extrapolations.

Only at 8x Zoom, with a +8 diopt., DOF isabout the same as with +4,5 diopter at 12x... (1,4 - 1,2mm). I hope Sven can confirm or correct these statements.
