Hi dpc'ers,
I haven't been participating in this site (or photography) for quite a while, as I've been busy with other aspects of life. But I'm starting to ramp up and get into photography again and want to start submitting to challenges again, to try to work on improving my photography.
Anyway, to my question:
I've been doing some research on this 35mm f/1.8 lens, and have found that there are many reports of "purple fringing", but that it is normally corrected in most cameras jpg processing, but apparently not the D40. But, these reports state the the Capture NX2 software can do the correction as well.
Does anyone use this lens with the D40? I'm interested in hearing your experience, if so. Do you see this purple fringing? Are you correcting it using Capture NX2? Is this an easy correction, or do you find it a pain to deal with?
Just trying to decide whether I should buy this lens, and thought the dpc community would be a great place to ask.
Thanks,
--Pete

Thanks for the reply, that is a very professional looking shot!
Glad to hear you haven't had any problems with the fringing with that lens.
I take it that you have been happy with it then? You would recommend it?
I wanted to get it for a faster lens for lower light situations. So far, I only have the 2 zooms that came with my D40 kit, the 18-55mm and the 55-200mm.
Thanks,
--Pete

this was shot using an f/5 aperture. purple fringing usually only shows at wide open apertures and only on contrasty objects (i.e. tree branches against the sky) and only in the edges of the photo.
so the photo posted is not a really good example for the lack of purple fringing...;-) |

true...
I have many shots with this lens... what type of scene would show this fringing? |

A wide-open shot of a landscape with a lot of trees on a very bright, clear day (overcast works better, but it has to be blindingly bright). Metered as dark as possible while keeping the sky overexposed As long as there are a few stops difference between the trees and the sky, there should be a purple fringe where the trees and sky meet.
Here's an example of exactly the type of shot I'm referring to:

SLRGear.com tested this. Here's a link: //www.slrgear.com/reviews/showproduct.php/product/1243/cat/12 Click the "Chromatic Aberration" graph to bring it up to full size. Seems like when it's stopped down to f/8-f/11 it's worst, which is sort of unusual. |

hmmm.. all the shots I have along that criteria have the trees out of focus behind a subject...
all I can tell you is that in the several thousand pics I took, I never took a pic of a tree infront of the sun wide open... so if that's the type of pic that would show purple fringing, then you shouldn't worry about it, because you'll probably never do it...
are there any other types of sample pics you want to see? I have thousands of shots using that lens... just let me know =)
Here are some pics taken with the lens wide open (1.8) using a D40 at iso 400... check em out...

On-camera flash on bright shiny stuff can cause fringing, too. Also, bright white things in the middle of the day when exposing for something darker so you just barely blow the whites. I can't think of any other things, but there ARE other things... it's almost always blown highlights next to either properly exposed stuff or underexposed stuff, and a quick transition (sharp edge) from one to the other.

That lens seems to have the worst aberration at f/8-f/11 ;).
ETA: And again... toward the edge of the frame.

Thanks everyone for sharing the info.
Its surprising that CA is at its worst in the f/8-f/11 range. From what I've read that range is considered the "sweet spot" for many lenses? Is that correct?
It sounds to me like I should be able to use this lens with no problems in most cases, and especially for what I intend to use it for the most: shooting using available light in low light situations.
