I'm sure I have a 70-200 Sigma ( not the f2.8 more like f4-5.6 )with a 58mm filter thread, but can't find it on the web anywhere.

There is a Sigma 70-300 f4-5.6 available though for a reasonable cost.

I'll check it when I get home.

Holy pooh!! By the way I have no idea what you two are on about tbh, I've just seen on a few forums that to get the effect I'm after I need a lens with that kind of specification!

...with that lens you would have to stand back quite a way to get a pic of the Lupo. If I have a chance I'll take some shots to show the difference from the same point at stages between 18 and 200. I don't have a 500mm lens though.

Its not specifically for the loop Ray, I'd like to get into photography as a hobby but am a bit strapped for cash and I guess I may be running before I can walk, but I have a bridge camera with an adapter than can be fitted with 58mm and 72mm filters/lenses and as the standard bridge camera will struggle to get a really shallow depth of field I've heard that with one of these lenses you can greatly alter the depth of field, even with a bridge camera.

You are looking for a multiplier then. Which camera do you have.

I also have a bridge camera, a Canon Powershot S3IS, and I bought an adapter tube and the x.75 wide angle and x1.5 zoom "lenses".

You can't just put a SLR lens l;ike has been pointed out on.

What bridge do you have?

These are the sort of things you are after. These are cheepies from eBay...

...they screw on to your adapter the x.45 will multiply your lowest wide angle by x.45 to give a wider angle and likewise the x2 will multiply the longest zoom of your fixed lens x2.

I have the Canon models x.75 and x1.5, a lot dearer then these I can tell you, and tbh I'm not overly impressed.

Hence why I upgraded to a DSLR as I had outgrown my S3. That said it still takes great images and I regularly pick it up instead of the 450D.

I've got a Fuji Finepix s1730 buddy. I will eventually upgrade to a dslr when my ability deserves one! Its annoying driving passed things and being like ooooh that'd make a good shot but be travelling down busy roads with nowhere to stop off!

Which one of those would give me a shallower depth of field Ray? Or should I try both? I'm looking to get a shot where I focus mainly on an object close to me and the remainder of the shot is quite blurred.

It's a bit technical really but depends on your aperature (F*) and the distance you are from the object.

Here's a calculator.

You may want to get both adapters\converters as you can get good shallow depth of field from both zoom and close up shots, but these 'lenses' will really only work at you extremes of wide angle and zoonm already on your camera.

For shallow DoF shots you need to be getting the F* down to as low a number as poss (which is the bigger aperature), so switch to Av priority and have a play.

The weakness in your camera is that you have limited F* settings.

Have a look on Flickr at some pictures of the style you like and look a the Exif dat by clicking on the camera model in the top left right hand corner.

You can get an idea of what you need to do to get the effects you want.

Here's a couple of mine taken with my S3 with no adapters, whcih I am happy with...

Yes, it is. Since replaced though.

I was trying to work through DoF with a work colleague and his FunePix s1800 and the S3 has more F* settings than that.
