Next, CA tests at different aperture settings

All images taken with the same exposure using manual mode


Full frame image

100% crops of top right hand corner to show CA





the CA is actually quite well controlled

[ortega]

Magnification - manual focus set to minimum
for greatest magnification at maxumum focal lenght

image resized to 700px wide

Bokeh

set to get minimum dof and maximum oof of background

I have also at the same time done the same test for the

Sigma 18-50mm F2.8 EX DC (not the new macro version)

and the

Tamron SP AF17-50mm F/2.8 XR Di II LD Aspherical [IF]

Can put them side by side?

Is this the Nikkor lens that comes with the Nikon D70?

D70 / D70s and now the D200 (hv seen the D200 KIT on sale in some shops)

[ortega]

yes it is

as above by scenar

I find this lens holds well against the other lenses tested
only the lack of the big aperture

now if i can get my hands on all the nikon kit lenses for a week or two, i can do a quick test to compare

maybe it is best if you open the threads in different windows
i don't want to start too many threads on with the same content

Great review bro.

Don't you think the color / contrast and Bokeh of the 18-70 is much better than the other two ?

I feel so
