Okay, I found the color shift on the 7 with the Biogon 25. I think, like the Elmarit 24, whether or not the shift is evident depends both on your proximity to infinity and the physical proximity of the subject. Shooting a wall (or a wall of trees) that fills the frame thirty or so meters in front of you won't show the shift even at infinity, but a sweeping landscape will. Corners are about the same otherwise. Edges look great. It'll be easy enough to profile and correct but, like with the Elmarit, my guess is the number of times it'll be a problem for my use will be fairly low. I forgot to take the 5r with me, so I'll have to try that out later.

Both are at f/5.6 processed in the same way as the backyard shot. First shot is followed by a bottom edge crop, second is followed by a corner crop. It's been very hazy here with the forest fires and the high (for us) humidity, so not really the best day to show off the lens on the whole, but I found what I was looking for.

Welcome!

Amazing 3-d look in these... great shots.

Thank you SKumar25!

Went out with the Biogon 25 on the NEX-7. At infinity there are Margenta problems.
Not on these closer by shots so much.

That's really cool. Here's a picture from yesterday, also with some heat shimmer, but due to something else:

You can see the "chop" effect the propeller has had on the heat from the exhaust, then when it hits the wing things get fuzzy.

This is a 100% crop from a hand-held shot with the CV180 on the Nex-7.


cool! i've never seen that before.

one from the g28:

Me either!

freaklikeme - thanks for the pics. Very interesting how variable the shift is. Usually when I get shift that strong in some of my shots, it's still noticeable in others (meaning with other lenses, no personal experience with that one).

The results, color shift aside, look pretty good. I think if I didn't already have the Elmarit 28 I'd be looking at getting the ZM25.

Speaking of the Elmarit 28. . . here it is at f/2.8. Also speaking of Summer on the West Coast. . . Seattle doesn't always get much of a real summer, if any at all, but we do occasionally get a stretch of really glorious weather. This week looks to be one of those - 88 and sunny today.

Agree with freaklikeme about the colour shift with the Biogon.
Close by it performs quiet well on the NEX as you can see in the tractor series.
Well I am glad I tryed it but I must say I overall prefer the lens on the GXR.

Where it is very obvious also is with surfaces like the next picture.







This one is a 5 image stich at infinity. I tryed to stich them before doing PP on each photo individually.
You see a dark vertical line above the bush. I tryed to get rid of it but it was beyond my skills in ACR. Very annoying.

Anytime, and yes, with the exception of the Elmarit 24, that's been my experience as well. I don't have a shot with the pre-ASPH Elmarit 21 or CV 15 that don't show the shift, regardless of focusing or subject distance. Which version of the Elmarit are you using?

went to the beach today where it was unusually hot (for SF). here's a 50% crop from nex-7 + nikkor 105/2.5 AIS:

who says only the x-trans sensor can produce a watercolor effect?


That's cool. I love what it did to Cliff House.

That happened to me to a lesser degree when I was in Aptos last year, only the air temperature was fairly cool (mid-70s at the peak of the day). So I panicked when I saw the results, thinking there was something wrong with the camera, and it was probably an hour before I thought through the fact that the sand had the sun beating down on it all day, so the surface temperature was high, even though the air temperature was mild.


yeah, i probably would have been freaked out if the effect were less dramatic. i could really see the distortion happening in front of me without the camera.

i was fooling around and broke the picture into 4 little pieces (all basically 100% crops) that i kinda like:







I like the first one. The background kind of kills the second one for me. This one feels like a game. "Spot the vaguely pornographic elements."

Interesting. I wonder what causes that behavior.

I agree, though the trade off with the GXR, aside from resolution, is that you'll be correcting for moire instead of color shift. Even on the 7, moire is an issue with this lens (it's evident in every highlighted bit of fence on my first infinity shot). I really wish the GXR made me want to use it, but perfect corners just aren't enough to make me want to bring it instead of the 7.

And, yeah, there's no way to get around correcting the shift first before stitching. It's just like vignette correction, if you don't do it before stitching, you will likely never get it corrected on the full image.

The latest, the ASPH. It's tiny!

Nice. And it is tiny, particularly compared to the Biogon. What would you say its strengths and weaknesses are on the NEX?

Nice sets Paul / Sebboh.

Sebboh, enjoying the old school Leica rendering...

Hmm.

+ great colors
+ high contrast
+ tiny
+/- f/2.8 is good but can feel a bit limiting some times
+/- strong vignetting at f/2.8, I generally like that though
+/- 42mm effective FL is good; I like it better than 50mm I think in general, but close to 35/36mm (I don't have a 24 that I use right now, though, so I guess that's moot).
- high contrast, when it's overcast around here it just takes some work to make the image not look like all white and black
- needs cornerfix on the 7 (but not on the 5N or 6)
- I like ZM-style focus "nubs" better than these poky tabs on the Leicas. The only ergonomic thing I don't like about them really.

Just picked up a few lenses in a Brussels flea market - MC Tele Rokkor 135/3.5, MC W.Rokkor 28/3.5, Minolta Variable Auto Teleplus 2x/3x + Tube (all in original faux-leather zipped cases!) + Vivitar (28xxxx Komine-made) 70-200/4 in FD mount. All glass dusty but flawless, after a haw/rub of my shirt - and all for a grand total of Euro 50.

Can't google any hard info on the 135/3.5 - all MC versions I've found are QF (very different looking lens), but mine looks almost identical, but not quite, to the MD version. Has built-in hood. Initial 135 shots, wide open or a half-stop down:

Maybe f5.6 or f8:

Closed the hood & aimed upward toward sun for this, wide open, just to see how it coped (sky was mix of cloud and bright sun):

Bit of purple fringing to remove in pp, otherwise seems pretty good, if I can hold it steady! The Rokkor 28/3.5 and Vivitar both seem very sharp from initial snaps. I wonder how the tele-extender will work?
