An example of why the 77ltd doesn't suck

.


Inspired by "an example of why the 50-135 doesn't suck" thread - let's try to keep the 77ltd
from getting jealous.

(also - I apologize if this thread inflames someone's dormant LBA and forces them to
hit Adorama for the 77ltd, but hey, it's a dangerous world.)


OK, let's start with some 3-D-ishness:














(These were also posted in aegisphan's excellent "can you please post your bets 3d images" thread)

You'll get no argument from me. excellent series of shots and it's a great lens and about the right length for portrits as well.

smooth smooth bokeh, nice photos!

as an aside, i notice in the 2nd and 3rd photos with the branches, there's kind of a double line on the bokeh ... is there any lens that can avoid that with thin linear details ... or am i looking at it the wrong way

I'd love to try this lens beside my 85/1.8 SMC Tak...looks nice. A little harsh on the sharpening, did you use an ultra-fine (0.1?) radius USM?

No - jpegs sharpened in picasa, so probably courser sharpening than USM ultra-fine .1 radius. Not sure what the picasa default algorithm is.

I tend to be lazy & leave most of the IQ up to the camera/lens combo.

it's probably got the most "magic" of anything I've got or shot. I'd be interested to shoot back-to-back with a 70ltd, but certainly am not interested in buying a 70 as I don't think it could be "better" than the 77.

I don't see what you're talking about. Care to explain? My 77mm never suffered from this and I have other Pentax lenses that don't as well.

Aha! I knew they would come out of the woodwork!



Vizjerei, there is some CA you occasionally see with the 77ltd (if the photographer isn't careful,) but personally, it really doesn't
matter to me - here's pretty much how I find myself judging lenses:

Center sharpness: 50%
Bokeh: 15%
Contrast: 10%
Color: 10%
Edge sharpness: 10%
CA + PF + Vignetting + Barrel distortion: 5%

Some people just can't get around CA/PF, but to most folks (IMO,) that just doesn't matter nearly as much as sharpness/contrast/bokeh.

I think the Voigtlander 180 APO Lanthar does not do that too bad, and also my FA 50 1.4 is
pretty good in that respect. But I think almost every lens will do that to some extent to a
'line' object that appears within a certain range in the DOF. Right close to the subject, it's a single line,
a but blurry, moving further out, it becomes a bit 'double', and then past a certain point it just blends.

Took the 77 to baby swim (er, splash) practice. The 50-135 is a better choice for this -
from where I was sitting, 77mm wasn't quite long enough without cropping... Below is a
tight crop from the 77ltd - instructor dunking the little guy!

For me, I do not mine CA much at all. Plenty easy to PP out from raw files, and future cameras (like the nikon d300 for example) will be able to take it out real time.

Now LoCA, now that is a bitch to post process. Usually it does not matter, but it can be annoying at times.
