That is, taken on a lens with focal length ROUGHLY* equivalent to 50mm on a 35mm SLR.

oh - that would take calculation as I have an 1/1.6 - does that mean I have to get right on 31.25mm?
Show me what you've got
I just found out that I can't search in Lightroom by focal length. So that makes it tricky.
I have a Canon 50mm lens and I can search on that, but that would be a focal length of 80mm
I love photography.
Here's a few (all a900 / 50mm f1.4)...

I do have non-gratuitous DOF shots, but where's the fun in that?
Can I assume that mine never look like that due to "slow kit lens" rather than "clueless photographer"?
I've recently bought an EOS 550 DSLR and really wish I knew how to use it properly! I have taken lots of fantastic pics but far more through luck than skill and I just try all the settings until I get one I like!
I have the standard Canon 18-55 lens and Sigma 10-20mm which I use for wide angle internal roomshots - is there a good idiots guide to DSLRs I should look at so I can understand what on earth a900 / 50mm f1.4 means!?
Its the Appeture value that gives them the impressive lack of DOF.
Basically the lower the number (F) the lower the DOF you can get. It doesnt have to be such a low number but the other benefit of such a low F value is that it lets in lots of light so you can have a reletively fast shutter speed so reduces the chance of motion blur or camera shake.
I think these type of lenses are sometime referred to as fast glass. It doesnt have to be expensive as the 50mm 1.8 for the canon is available for under £90.
This is from a total beginner trying to understand so please dont rip it to pieces on technicalities
Alex Simon, after your intital comments I'm waiting patiently for your perfect pics.
Distance to your subject and focal length of the lens come into it too. This is a very handy tool for seeing how it all adds up:
DOF Master
I can't recommend getting an inexpensive 50mm f1.8 highly enough.
Totally transformed what I thought about my camera and how I composed images. At the time there was a Scottish guy on ebay doing the Canon 500mm f1.8 mkII for £60, but all camera and lens prices have gone up since then.
Its the Appeture value that gives them the impressive lack of DOF.
That's what I thought. So the 18-55 kit lens at, ah, 4.5 iirc just isn't up to it, even at max zoom.
I thought that 'fast' lenses was what really pushed up the price...?
Hard to find lenses on eBay cos the vast majority are people trying to get rid of kit lenses.
I'm going to cheat as according to a little plugin I downloaded, I've only ever taken 6 shots at between 31 and 32mm. So here's a couple of 50mm lens shots on a 1.6 crop sensor (80mm equivalent)...

Here's one I fluked a few years ago with my old EOS 350d - according to the software it was:
Exposure 1/2500 sec
Aperture f/3.5
Focal Length 18 mm
ISO Speed 100
Exposure Bias 0 EV

and this is another one
Exposure 0.001 sec (1/800)
Aperture f/5.6
Focal Length 49 mm
ISO Speed 100
Exposure Bias 0 EV

I think these are pretty good but guess I just need to spend more time playing around with it to see what the various settings do.
What's a crop sensor BTW?

Somewhat, but DoF can be made narrower even with a larger aperture by focusing closer to the camera or (I think) zooming in...?
The DoF in those pics above isn't really all that shallow anyway, should be achievable on a kit lens. You do know how to control the aperture with the A setting don't you?
Alex - love those pics
Although the kid/breast one has been heavily smoothed in something like neatimage/DXO hasn't it?
My choice in prime lens is basically limited to the Oly pancake 25mm f2.8, and it's really the portability I am interested in.
Try again - not sure why Flickr has hidden those:

What's a crop sensor BTW?
They mean a sensor that is smaller than a 35mm film negative would be. It ends up magnifying the image compared to how a 35mm film camera would take it.
The crop factor is how much. So a 50mm lens on a Canon would be like using an 80mm lens on a 35mm camera, cos the crop factor is 1.6.
Think this is the only one I can find here at work, our old departed moggy
Hi Molgrips - yes there was a tad of smoothing - just manually in photoshop. Not as much as you'd think though, it was just that I was a bit of a novice and heavy handed. I also brought out a bit more contrast around the eye.
As you seem to be allowing my 50mm lens shots:

Dont play with your food by tryingtimes, on Flickr
That is pure class
Just a hobbyist, Alex?
Thanks molgrips
Yes, although I have done one commission.
Most of these were done for a monthly photo competition on AVforums
http://www.avforums.com/forums/photo-competition/
Very friendly and encouraging for 'ordinary' photographers. I tend to need a focus to get me going!
I'd spend hours snapping if I could - family time gets in the way, although they are very indulgent of me
Can I share a link to that spaghetti one on my FB?
"DONT" requires an apastarophe.
My choice in prime lens is basically limited to the Oly pancake 25mm f2.8, and it's really the portability I am interested in.
That does seem to be a drawback with olympus. The primes are pretty mediocre. I'm pondering the Panasonic 20mm to replace my rather pants Olympus 17mm at the moment.
AlexSimon - Dont play with your food - very nice image, very commercial too, thought about licensing it?
Molgrips - go ahead!
Cougar - it sank
rewski - I'd happily license it if I know how to go about it in a way that wouldn't be a waste of time. I use Dreamstime as a buyer, but I find it hard to see how sellers make more than a couple of quid from each photo. Any ideas?
Email Heinz, for a start! Or their ad agency - that would be better.
That could be a great ad campaign right there, in that single shot.
It's the sort of image you'd see on a card in paperchase, they have an in house design team
Greeting Card Buyer
Paperchase Products Ltd
12 Alfred Place
London WC1E 7EB
or kids t-shirt, would have to convert to an illustration though
hmmm - good ideas. Thanks!
I guess if I were to pitch it to Heinz I would have to turn it into a campaign - one for ketchup/salad cream/other kidsy food products.
hmmmmmmmmmm
Ah yes.. kids' tshirt would be the best bet.
You could do a whole range of witticisms for all ages along similar lines. Visual puns based on various kinds of movable lettering.
In fact.. it'd be a great topic for a photo competition..
Enough with the shallow DoF!
