I use my 50mm Mf1/.7 for everything now, pretty much. If I want a wider shot I take a few and stitch them together with Hugin.

The lens was 7 and is more than sharp enough. Food for thought?

Thanks for the ongoing tips :) I can't use ICE as I run Ubuntu, but I am happy enough with Hugin: it too has a very attractive price :)

I've not tried the weighted string method to remind me where to rotate the lens, but I did try a reasonably close 3-shot stitch of a shop-front when I pointed to about the centre of the 50mm and rotated around that, and it seemed to be pretty accurate in terms of parallax. I must work out where the no-parallax point is and make myself a pano head - Pryds: Build Your Own Panoramic Head (Novice Approach) Pete's Cheapo Nodal Samurai Homemade Panoramic (Pano) Head 'L' Bracket. - as I say, the results from rotating it around the centre of the lens barrel seem ok so I guess it's roughly there!

(will edit to add sample image later - host i splaying up at the moment)

I do try to have a lot of overlap having ended up with gaps in my earlier tests:

but it doesn't seem to take so much longer if you go out of sequence - this is three shots taken in the order middle, right, left. I guess if you did many more shots and they were out of order processing time would suffer badly though - good point!

I bought a M 50 f1.7 and I love it, so it's always on my camera because photos taken with the 18-55 now look a bit fuzzy to me. It's rewarding to use, but it's a tad long on APS-C so I've started taking multiple exposures and stitching them if I want to capture a static scene that's wider than the lens allows.

I'm shooting RAW and processing the files in darktable, then stitching them using hugin and I'm fairly pleased with the results (albeit I need more interesting subjects - the shots below are part of my learning process)

I just wondered if anyone has any tips I might be able to use? I'm handholding so the rotation of the camera isn't perfect, so on shots like the one with railings I sometimes get things not quite lining up - or rather I always get things that don't quite line up, but it's more obvious when there are man-made straight lines!

Anyway, here are a few of my test of concept shots. Any ideas for things to try in the software or with the camera much appreciated, as would be any shots taken with a similar technique to inspire me. Ta.

ipernity.com is how flickr should be. Heck, it's how flickr was earlier this week. There is even an 'import from flickr' tool. It has the same pricing plan as 'old' flickr.

Did you mean "I have to agree with earlier comments, 1TB of free storage can only encourage people to upload any old rubbish and bring down the average quality of the site."

I had unlimited storage for $25/year. Flickr's old pricing encouraged you to do so as there were limits on free accounts. Now there is no incentive to pay because it's twice the price, and all you do is remove the ads for that.

The comments that were part of the community are hidden behind 'click here for more comments' links even when there is room to show them and you only get two lines to comment in - albeit the box scrolls down as you type, but still it doesn't encourage considered opinions to be expressed, just comment son the level of the average facebook comment.

That combined with the Facebook-style mosaic and the effectively unlimited storage means I fear flickr will become the worst of a combination of Facebook and Photobucket.

They might as well have changed the name to 'that site that people used to upload photos to' while they were at it.

Also, where the hell are my sets? I want those next to my pictures when you look at my profile.

I am Pro (well, I'm not now, there is no such thing as Pro now) so I can renew at the old Pro rate for as long as Yahoo decide that they have to let me before I decide it's too much effort to move and make me pay $50 for something that used to be better and half the price. Don't imagine for a moment that if you are Pro now it will remain half the price it is for everyone else. The pricing model suggest that showing you adverts is worth $50 to them, so they won't let you avoid them for $25 forever.

DA 35mm f2.4 AL vs M 50mm f1.7

Some real food for thought here - thanks everyone. I hadn't considered the 40 XS before - that could be a good compromise, especially as I take my camera pretty much everywhere with me.

The angle of view/perspective thing is very interesting - I need to read up more!

I have thought about a katzeye screen or similar too, but I do quite like AF as it means I can use the camera without my glasses :)

DA 35mm f2.4 AL vs M 50mm f1.7

I have a M 50mm f1.7 which was an absolute bargain at 7 ($10US) It is so sharp that it is my 'always on' lens, even though focussing is a bit difficult with the standard focussing screen.

When I use my other lenses now I'm always a bit disappointed that they are not as sharp as the ones taken with the 50mm. However, it's a little long on a cropped sensor so I was thinking of getting a 35mm DA instead, as this would allow me to use AF again, as well as being a little more of a 'natural' length.

I was wondering though how the lenses compare. Will I be disappointed with the 35mm after the 50mm in terms of image quality and sharpness? Would you recommend something else at 35mm instead? I don't mind manual focus too much, but AF would be nice - AF and focus shift would be ideal. I also don't mind buying secondhand - so any recommendations or advice would be much appreciated.

Nothing wrong with the k-7, it's my only camera :)

I wouldn't get another if it broke, but hopefully it will last a good while yet so there will be plenty of k-5s for me to buy second-hand when the time comes!

I'll agreed with that. My 50mm/1.7M was 7 ($11 US) Unfortunately postage was 4 ($6.50) because it came with a camera attached to it, but it was still an absolute bargain.

As I am genuinely a rear cap short now, I use the film body as a rear cap for my kit lens.

A friend of mine at school worked for years on his Saturday jobs and so on to buy an M3. I wondered at the time why he'd bothered, but then I guess that 20 years later he could get his money back at least, so it will have cost him nothing to own.

I do wonder how the values of old bodies will hold up when you can't get film any more though.

Thanks - I was struggling to get an image with over and under exposure at night - I ended up with an Ikea lamp pointing at the wall with a picture frame in front of it. I guess the bulb doesn't have much in the blue end of the spectrum then!

If you could show me the results on the following file http://ubuntuone.com/45jUfezj04hA1Depr9wgnb that would be fabulous. It's a slightly off-focus image of a splendid old car I saw at the local shopping centre the other day. My best effort at de-noising it is here

Thanks again - as a k-7 user the ability to remove noise is very important :)

I tried to do the k-7 last night, but I didn't seem to have the tools in my install (1.1.1 on ubuntu)

I then followed the instructions to install fron GIT (no real idea what that means!) but then I couldn't run darktable at all.

I will upload my images when I get chance - may have to create a dropbox account too. Thanks!

What lens do you have on?

If it's asking you for focal length it's either an old lens, or a new lens with dirty contacts, or not quite on properly - this means the lens can't 'talk' to the camera to tell it what focal legth it is, and it also means it can't calculate exposure properly because it doesn't know what aperture the lens is at.

Try taking the lens off and putting it on again until it clicks, if it's the kit lens. You should then get all the modes.

Please don't take my comments as criticism - I like the b/w one. I do think the child looks concerned, or at least uncertain - but that makes the image more powerful, if not quite the picture you hoped to capture.
