Which filters to FA 31mm & DA* 60-250?

Not sure what kind of reflections you want to get rid of. If it's reflections from shiny stuff in the environment you are photographing, like water, it's a polarizing filter you need. But that's not a good filter to use for general protection of the lens. If it's reflections in the lens itself, like flares and other reflection related abberations, you will not decrease them with an extra filter you will only get more AFAIK.

K3 shutter rattling when battery low

By what measure? mAh is not the only measure of a battery you know. If it can't keep the same voltage at all charge levels and loads* as the original it's probably not better if the product it's used in is as voltage sensitive as the K-3 seems to be.

Edited: *Load is probably the greater influence on output voltage in this case.

So, is the M 50/1.4 different from A 50/1.4 in this regard, or is the M just regarded as cheap while A is not?

Why deactivate SDM?

Earlier versions of the sdm-lenses were prone to break and when they did, the lens would not auto focus at all even if it had screw drive. The camera still detected the sdm and tried to use it instead of engaging the screw. Also, I guess some users didn't trust sdm because of this and decided so make a preemptive strike by disabling it, or they felt the screw drive was faster than sdm.

I thought the sr used internal accelerometers to stabilize the sensor and those should not be fooled by anything like this. But it could be that in video mode it also uses some kind of image analyzing as well and that would certainly be fooled by flashes and strange video backgrounds in the scene. So that's probably it.

If you are seeing this effect on your RAW images, you should check your display. Probably running in a low colour mode or just bad at colours.

A seal on the mount does not make the lens magically weather resistant. There are still other places for dust and water to enter the lens and also probably through the lens into the body. I'd think the mount itself is far from the weakest point in a system that is not weather protected.

I use duplicati (also free) I like it because it uses standard components so I will be able to access the backups from other platforms and even if duplicati is not avaible in the future for some reason. I can scedule for how often/when incremental and full backups are being made and how many full backups to keep. It supports several different protocols (ftp, webdav etc) as well as several different online backup services (mictosoft live skydrive, amazon s3 etc) and there are versions for windows (32 and 64 bit), mac os x and linux.

Colour problems with LR4 exports.

The xrite is a bit more expenive than I'm prepared to spend. I'm not a professional after all. :-)
I'll check out the other softwares as well.

The stripping of sRGB thing was more like a hypothetical question. I'd like to understand this concept more. Like why I get the results I get when the web gallery software scales my images. The rescaled versions loses all exif-data (checked with PhotoME) and the colours are bad. But if the browser assumes sRGB if color info is missing, the images should look the same as the original wich has sRGB embedded? This is what I'm not getting.

Thanks for all answers from everyone so far. You are really helping me. I thought I had got a pretty good idea about how color management works. But there seems to be some gaps in my knowledge that needs to be filled :-)

Seems like a calibrator need to move up a bit in my priority list. I've been thinking about getting a spyder 4 pro. Do you have any other tips and pointers regarding calibrators?

Let's see if I've got this right. If I open a file without a color profile in a color managed software it is usually assumed that the image uses sRGB. So if I have a file with a sRGB profile and makes a copy in wich I strip this information they both should look the same anyway?

Colour problems with LR4 exports.

Oh crap. I feel so stupid now. I have just assumed that the problems I had today was related to other problems I've had (with facebook and NAS). So I didn't bother to open the files in another software. But as I thought of uploading samples to this thread I tried to open the problematic file in Firefox and it was fine. But picasa was still a problem, wich I found a bit strange. Why wouldn't google add colour management, that's just stupid. Well, It turns out, after a embarrassingly quick search, that they actually do manage colours. Just not by default in the previewer. So after I checked a box in the configuration marked "Enable Color management", I get what I wanted in picasa as well.

So I guess my problems now are not in my own system or software but a result of processing (rescaling) of my images on Facebook and on my photo application on my web server (NAS). I'm guessing if some instance removes the profile information from the photo, the colours get whacked? Is there a way to get around that? I wan't my images to look at least acceptable even for people who don't know anything about colour management.

I'm fully aware Facebook is not the optimal place to show high quality photos, so I consider that a lost cause. If I send a photo to a friend though, I'd like them to be able to see the photo as close as possible like I intended it to be with whatever software they prefer to use. But I guess this dilemma is what colour management is made for and tough luck if the software is not managed...



I got this far before realizing my mistake:
I have a stationary win7-64 system (intel i5-2500K, 16GB, AMD Radeon HD 6800, DELL) With a DELL U2711 monitor (27" wide gamut IPS display) witch I've set to sRGB. I don't have a hardware calibrator yet, but the colours doesn't seem that off. But if I compare images on the same display, the calibration wouldn't be an issue. I use the factory profile for the monitor though.
The originals are always RAW files (DNG).
I haven't tested this problems extensively using a host of different softwares and such, I was hoping someone would have an insight in the problem before I go through that. Locally I use picasa and Firefox 17 (explicitly set to use ICC version 4, at least some previous versions of FF didn't use that setting for some reason. Photos I've published directly to Facebook do look equally strange on my iphone and on other peoples computers and when I uploaded images to the DiskStation I got comments from my parents about the colourful photos and my brother thought I maybe should tone down a bit on my post processing ;-) ...

Yes. I'm exporting to jpeg.
There aren't that many relevant settings while exporting. There's "file settings" with "image format" (jpeg etc) "quality" and "color space". Other than that I can't see what other settings could have an effect of the output in that way.

Colour problems with LR4 exports.

I have a problem with my exports getting way too saturated and I don't know why.
The camera is set to sRGB and every setting I can find inside Lightroom is set to sRGB as well. Whenever I export to disk and view with picasa, publish to facebook or some other web gallery via ftp publish plugin the result is freakishly colourful. This have not always been the case, but I'm uncertain if the colourfulness came at the time I went from LR3.x to LR4 or at some time later.
There's one exception. The photos I publish via FTP goes to a NAS (Synology DiskStation) with a built-in web server and photo sharing application. The images that the application resizes for thumbnails and normal viewing gets colourful, but if I choose to download the original it's strangely enough ok (if I view it in the browser or choose to download and view with picasa. - I think I'll need to confirm this again, it's just too strange).

Today I wanted to send a photo to a friend. So I made an export and opend the file in picasa to see if I got the right one and I got the colourful version. Then I tried to export again, this time setting AdobeRGB in the export setting, and it looked alright this time. Well fine. I could be content at this point, getting the result I wanted, but I'm not. Isn't it supposed to work? I expect LR to display the photo's in the same way they are going ti be displayed when exported if the settings are the same from the camera to the exported image. It did before.

Sorry for the rant, it seems like this post got to be some sort of outlet for my frustration I'm feeling right now :o. Please help! :(

FA 50mm 1.4 - aperture not adjusting
Posted By bengibollen
Replies: 5
Views: 1,195
The aperture blades are always open for metering and focusing reasons. It would be difficult to adjust focus or frame your subject if the aperture is closed down. The viewfinder image is dark, the AF sensors don't get as much light they need to operate at their best and the long DOF makes it difficult to know exactly where the focus point is.
The camera actuates the aperture lever at the moment you take the picture, just before the shutter.

Oloneo Photo Engine

I tried it during it's beta phase. The results could be very good. Nice tonemapping without disturbing halo effects in one end, and the usual stylish effects in the other. I never tried the part of the software where one could control lightsources in an image.
The thing i didn't like was the user interface. Things like navigating and selecting images with the arrow keys did not work and it was very slow when browsing in a folder with lots of images.
I have not tried the latest versions after it left beta, so I don't know if this has been fixed in any way.
My verdict is in any case: the render engine is really good, but the user interface really needs some major work.
