Well...I don't know about it.

Image quality is fine. Very sharp. AF hunts a little bit sometimes. HUGE flare issue when its wide open (understandably), but that dissipates at f's tighter than 2.2 or so.

I think it may just be that I'm so used to a more versatile arrangement of glass hanging off the front of the camera that I feel a little bit restricted. The digital conversion means this is essentially a 75mm lens, and is therefore not as wide as I remember a 50mm lens being.

It'll be a good portrait lens. It'll also do well with a stack of extension tubes behind it for macro stuff...especially in bright lighting.

Here's one of the first pics I shot:

Incidentally...

I'm back to having problems with Lightroom. When I export a DNG to JPG, they're turning out MUCH darker than the image looks in Lightroom.

A few weeks back, ValleyFan told me to switch to sRGB colorspace for the export. That fixed the problem. But now, its happening again even though I export in sRGB.

The only thing I can think of that might be happening is that a change in the camera might be causing it. Would it be possible that the camera shooting in sRGB (instead of Adobe RGB as I had it before) could be causing the issue?

It's pissing me off, majorly.

EDIT: I just shot two identical photos, one with in-camera settings of sRGB and the other with aRGB. They both exported from lightroom identically. Both significantly darker than the version in lightroom.

Here's a handy little exif-viewer program:

Do you have Photoshop? If you do, try opening the file that you exported from Lightroom that looks to dark, see if it still looks dark in Photoshop. If it looks good in Photoshp, then the image is getting assigned the right color profile, and what you are viewing it in is not color aware (doesn't solve the problem, but narrows down where it is). If it is too dark in Photoshop, go to Edit -> Assign Profile, see what the current profile it (it is what it will say next to the Working RGB: radio button). With that dialog still open, change it from the working RGB setting to Profile: and try pulling that down to some of the wider color spaces (Adobe RGB or ProPhoto RGB) to see if in the preview it looks like you are seeing in Lightroom. If this works, then it is somehow getting the wrong color space tag coming out of Lightroom, if it doesn't then we have an even deeper problem (at which point perhaps you could send me the RAW / DNG as well as the jpeg export)

The .jpg looks fine in Photoshop CS. It looks like crap in the .jpg viewer on this system (windows picture and fax viewer) as well as internet browsers, etc.

For a while since you gave me that first bit of advice, the windows pic viewer would display identical to Lightroom and PS. I don't know what the deal is.

Can you maybe suggest a better .jpg viewer?

I'll upload the .dng and the "clean" .jpg export and send you the links.

EDIT:

Here's the .dng: LINK

Sweet, so that is good, no mismatched profiles. There are better, color aware jpeg viewers (ACDSee and others) but really you want to get it coming out of Lightroom in the correct profile, because you still won't be able to post a correct looking image on the web if it isn't in sRGB (most web browsers are not color aware).

Are all your export styles exporting the jacked up jpeg? If you right click on an image in Lightroom -> Export... and select the top export in that menu, be sure that under the image settings that the Color Space is set to sRGB. Check the resulting jpeg. Then do the same thing, but now when you have the export dialog open, pull down the Preset menu at the top of the dialog, and set it to the one that is giving you problems, and be sure that is still set to sRGB.

EDIT - I see what you are seeing, and it looks like it is a profile mismatch, give me a second to take a look.

Wow, that is weird, it seems that Photoshop and Lightroom have a different interpretation of sRGB than everyone else. I save it Adobe RGB and it looks great in something like firefox, I save in sRGB, every thing but lightroom and photoshop are to dark. I'm wondering if they have a different sRGB standard. Still looking.

I've been using only one export style, a custom export preset to send it to a .jpeg at 100% quality in sRGB at 600 pixels per inch. I looked through the other presets, and are all set to sRGB.

Just downloaded ACDSee and it displays dark there, also.

EDIT: So I played around a bit with ACDSee. I exported the same DNG (the one I linked to above) in all three color spaces (sRGB, AdobeRGB, and ProPhoto RGB) and found the Adobe RGB to be the brightest and closest to the pic displayed in Lightroom. The sRGB was darkest, with the ProPhoto almost identical to the AdobeRGB.

With a completely different DNG, I exported to .jpg in all three color spaces and found that sRGB was the brightest and matched the display in Lightroom exactly.

WTF!?!?

sRGB/Adobe/ProPhoto

With the afternoon to kill, I took a short drive over to Cal State Northridge to photograph their Men's Soccer match vs. Cal State Fullerton. I went with merely the hope to hone my sports-photo skills. Here's a couple:






In my opinion, sports photography is so much less about technical knowledge than it is about knowing the sport you're photographing. Where's the action going to be and when?

Soccer sucks (:P) but I had a good time taking pictures.
