He he! I'm in no hurry to decide though. Going back and forth, looking at samples etc. is part of the fun.

Ouch, that was cruel; sadly, The Ladies have both gone to that kennel in the sky. I see your point but the Lady in question was just getting some air conditioning to the parts other breezes cannot reach; we were in the tropics and it got very hot there. Thanks for looking at my Blog. Jon

OneAnt, I just noticed you are in Aussie; was working there in Sydney for a while until recently. I must say the dogs were a bit tarty down under, which explains your confusion about my Ladies! No worries. Jon

I love your dog, he's a stunner, but get him contact lenses (Zeiss of course), that way the ladies can see his eyes better. We have a Boy now, Toffee, as you saw on the blog site - he's also very handsome but hard work. Looking forward to your visit, bring Bug.

Happy shooting,

That shot you took with the 85L with the yellow houses is terribly oversharpened. Thick white halos an all edges. Maybe that triggered bifurcator's remark. On the other shots it's not that bad. But sharpening definitely affects OOF rendition (and clarity (from LR) even more).

Has anyone addressed why the 85L's f/2 and f/1.2 images appear to be exactly the same? There should be a dramatic difference in bokeh, but there isn't.

If this is the case, I can fully understand it. This was just an old oversharpend JPEG as a quick example. But since I still have the RAW of this picture I will generate a new version and then exchange to above picture.

Boris

edit: Above picture exchanged.

I'm sure, that sharpening is affecting the OOF rendition. That's the main reason for me to compare them with some sharpening. I never use completely unsharpened images, neither for web-presentation nor for printing (the only case is iStock). So the only thing that really matters for me is how they compare sharpened.

You can see some differences between f/2 and f/1.2. But you are right, the differences are not as big as I would have expected.

Isn't it possible that the vignetting on the 100 MP affects your perception of "the shadows"? The vignetting really works for the type of shots you made, with the subject right in the middle.

--trajan

There was no perception of shadows ...the shadow detail is evident to all, Not a matter of taste or anything else ...simply the shadow details are there. You can continue the conversation with my girlfriend if you like

Comparing an 85 to a 100 ...has anyone considered that this is rather pointless as the FL is a major factor in the render of the background. What the zeiss has done is isolate the subject, render the bg and mid ground to a softer image. Now before anyone says they prefer to soften an image by using a lower contrast lens (less sharp to everyone else) ...look at the canons, the trees and the wall on the left in the 1st image ...they have lost so much detail that they have become a distraction and destroyed the image. The trees too have lost their black. I like your L but the point is becoming lost on me, the zeiss is a high contrast lens ...it preserves detail, the L cannot but if some prefer softer lenses then thats a bit like tinned spagetti to me.

Boris

In the anchor example, the subject (focus) is farther away in the f/1.2 shot. This can explain the issue.
The other two examples seem ok, perhaps the subjects and environment are not the best to show the difference between these two apertures (and also between the two lenses IMO, but thanks for the test anyway !).

If you don't equalize the framing the test isn't conclusive as DOF will be different due to different magnification. You need to shoot the 100 from further back than the 85. In the cannon (not Canon) shots the subject in the 100 shots is larger, so the DOF is going to be smaller. The anchors at f/2 are the same size, but at f/1.2 the anchor is smaller? Was it shot from further away? You can't then compare the background blur fairly.

Why are you sharpening lens samples?
You've added a lot of sharpening to all of these. How does that help anyone?
If I sharpen and stuff my $200 P&S can compete with all of these. Pretty close!

Bobu wrote:
I used my standard setting for sharpness in LR (50/0.7/100). Personally I find it diffcult to judge the quality of a lens with 0 sharpening, at least with cameras with bayer-pattern and anti-aliasing-filter.
By the way without sharpening my 200$ P&S images look much better than my 5DII images (but the P&S has only 4.7MP and no bayer-pattern).

If you and some other people would really like to see the above pictures with 0 sharpening I could post them here as well.

Boris

Ah, that's kewl. No, I don't need to see the images without sharpening. Thanks for the offer. I was just thinking: "Hmm, wouldn't it be incredibly hard or harder to judge both lens sharpness and bokeh when the images were modified - especially with sharpening." I didn't understand how that was useful or as useful. I'm not sure I do even now but if that's the accepted way I guess I'll figure it out.

Thanks for the reply.

Yes, that's what triggered it. Then I checked the images in this and his other three threads and there was varying levels of sharpening throughout. I also think that it affects OOF/DOF as well as perceived sharpness and resolving power (it does with my equipment) so I asked about it. It's no biggy tho. I'm not in the market for this lens or anything. But it's good to keep myself educated so if I do ever see one I'll know what it is and what it's worth.

I tried to equalize the framing by moving further away with the 100mm lens. But since all shots were handheld and there were some other restrictions, like fences, it was not always succesfull. This was just a quick test, when I had 30 minutes spare time, waiting for someone.
For some serious testing i would use a tripod.

This makes it difficult to compare. Had you used a slower shutter speed on the 100/2 to achieve roughly equivalent brightness, I think the comparison would be easier to make.

People whine and grief so much in this forum that it is a wonder people bothers to upload test shots.. If you don't like the premises and the results, find another thread to troll, or state your opinion humbly and soberly, stop acting like retards.
