New lens (image samples)

[Hodders]

Just got my new lens Canon 70-200L F4 IS USM. It has replaced my old sigma 70-300 f4-5.6 APO.

Below are 4 images, 2 images taken at F5.6 and F8 on each lens at 200mm (on a tripod).

All are 640x480 100% crops from the centre of the image.

See if you can tell which is which !

Image 1 for me, good clolour tone, sharpish image, although the trees behind in number 3 are a little better than in number 1, overall number 1 wins. Number 3 is not good at all, infact i think the tripod moved its that blurrly on my screen.

number 4 is too noisy for me over the red colour and with a soft focus.

So i hope your new lens is image 1 mate..

Image 1 is new lens f5.6
Image 2 is new lens f8 (slightly sharper than image 1 IMO)

Image 3 is old lens f5.6 (v soft)
Image 4 is old lens f8

Well chuffed with it !

What ISO were these taken at? Might just be the noise but i'd expect the centre to be sharper, my F/4L seems sharper in the centre at 100%.

are these 100% crops? If so I'm not impressed at all with any of them :s

That's an F8 100% crop from my 24-105 F4L and by all accounts the 70-200 F4L is meant to be perhaps sharper?

Is that sharpened at all? For a 100% crop that's staggeringly sharp!

 

[Hodders]

I will try to replicate the sort of shot you are showing. The difficulty at the moment is:

1) It's flipping raining and grey so no decent light anywhere.
2) The lack of any kind of model.

Out of curiosity - what lighting - I can see one flash - were there any other sources of light ?

The photos I took were taken earlier today from and the day is so grey and cloudy that everything looks so flat.

Your shot is very sharp - is that straight from the camera or has there been any PP ?

 

[Hodders]

Ok - try this:

ISO 400 - 70mm, F5.6 1/100th, no PP.

lol she's not that hairy!

very very light sharpen (0.5 radius 200%) as the 40D needs it, infact canon reccomend slightly more (300% 0.5) on the 1Dmk2 they look like that straight of the camera though (well, converted from raw with no sharpening on at all)

Totally unsharpened for you

What ISO were these taken at? Might just be the noise but i'd expect the centre to be sharper, my F/4L seems sharper in the centre at 100%.

And My Sigma 70-300 APO is sharper in the center, closer to image 1-2.

The Problem I have with the sigma is that even on Crop anything outside the center 1/3rd box is uselessly soft. That and the slow AF made me buy a 2nd Hand Nikon 80-200 2.8. The cneter sharpness between the 2 is comparable though, once the Sigma is stopped down to f/8 .

It looks like moderate USM has been applied but I'm not expert. Looks like a few sharpening artifacts and some areas seem overly sharp for any lens give DoF issues etc.

EDIT: But it is one nicely sharp image from a nice sharp lens, without doubt.

Ah ok, that's a bit more like it

Still a very sharp lens you have there - I'd say my 70-200 F4L IS is roughly on a par with that.
