so i went on this evening testing this time the 24TSE under tungsten light, which in this case wasn't an easy light source because several little lamps are directly shining in the lens. anyway, its a situation which i am faced very often in a similar way, esp if shooting interiors at night.
i will go on in the next days comparing the 24tse together with the 1,4extender against the rodenstock digital 45mm lens and the 45tse against the 60HR.
to read the tests together i post here the links to the other lens tests:
23HR against the 17TS-E:http://luminous-landscape.com/forum/index....showtopic=39838
because the 24tse is wider than its equivalent 35HR lens ( on a mf sensor with 36x48mm ) i tested also the 28HR against it,
which is again slightly wider than the 24tse, but if stitched together to the max. frame size the resulting fov is quite similar.
what surprise with the 28HR because its behavior in terms of flare isn't very nice under the light source i had here.
in practice i never felt this being a problem, but of course i never have shot side by side with various lenses comparing them directly.
normally the 28HR is a quite a nice piece of glass, but here it showed some strong internal reflections.
not ot misshape the impression of this lens i dont want to post it, its a very unusal behavor the lens showed at this setting.
i will give it another chance in another moment, its not fair to pick up such unfavorable setting, if this is a singular situation, and so it appears to me.
the 35hr reacted way better but still behind the 24tse in terms of flare i.m.o.
i exposed both images to the extreme upper limit, just so that there has remained a bit of texture in the white tilings in front of the cam.
the shots with the HR lenses show more detail, but noise seems to be better with the canon and especially its no- flare behavior is fantastic.
the mf sensor seems to render better zones with very lo contrast, as the blue wood at the roof.
i saw this in the outside shots too, esp. in the grass area, although not sure if there wasn't a bit of back-focus too in the game on the canon shot.
i prefer the colors of the e75, they are more "real" but most likely its a question of tweaking the colors either in a profile or in photoshop.
with the 35HR appeared a problem i never was concient: the extreme upper left edge is unsharp. i have to check which caused this.
all three other edges are ok, so it could be sth. in the lens which isn't aligned very well. sh.....
to show the possible image circle i shifted all three lenses as much as possible up and down and combined them in ps. to one shot.
the canon would have if stitched in that way app. 47 mp. the HR shots with the e75 53mp. not a big difference, the reason for such small difference
is caused by the same shift way of both lenses but the slightly smaller pixel size of the canon.
both shots were taken with f11 and tethered to my macbookpro.
i shot with 1,6 / 3 / 6 seconds and selected for both the 3 second expsure.
both programs were stable, except eXposure 7 crashed one time ( in app. 1 hour of work ) for unknown reasons.
i prefer the tethering of the canon for its bright big preview which makes focussing quiet easy and perfect,
the live view of the e75lv is a big help compared if it wouldnt be implemented,
but under lo light conditions you cant stop down the lens to focus correctly because contrast for the live view
gets to lo.
i marked the original frame size from a unstitched unshifted single shot red.
here we go: first image is the canon, than the sinar both images are app. 50% of their original size, the crops are 100% .
and now some 100% crops.
upper image always is the canon, image at bottom the e75.
