Ive never bought any lense before and since i have an A60 and an A75 and my brother has an A60 and an A70 i figured i would get some lense we can trade and swap em around.
I like the idea of the 37MM lense because it doesnt block the AIAF and the viewfinder. But will this zoom lense fit?
This adapter
This zoom lense
Will any "37mm" fit this adapter? I like the idea of being able to manualy adjust it.

| That lens won't work. It's for a pentax slr with a screw mount. (at least that's what the description says) |

I think your "lenses" will be limited to the Standard "telephoto" and "wide-angle/macro" you will see on Ebay for your camera. You cant add any lens designed for an SLR.

| I agree. My buddy has that camera, or one very similar to it, and he has the 37mm adaptor with a 2x Kodak telephoto lens to attach to it. I'm pretty sure he got it at Best Buy for about $30-$40. |

So what does 37mm mean? is that the thread spacing? the lense diameter?
Why exactly wont it work? the distance of the lenses or somthing? Will it not even focus? im not sure i understand. |

Reverse the lens and you might be able to use as a macro lens/lense.

The 37mm is the thread diameter.
It won't focus, what you need is a lens that "modifies" the lens already on the camera, not one that's intended to be the only lens on the cam. Different optical designs, completely.

Its the thread, like you thought-- Your camera needs that adapter,, once on, you can screw on Filters, and some telephotos/wide-angles, for your camera..
Something like this--
ebay
You cant add on SLR lenses to your point and shoot, sorry..

I think you're misunderstanding. The adapter looks ok. The lens you point to is for an SLR not a Point and Shoot like you're camera. The 37mm referred to in the link is the focal length of the lens not the filter thread size. |

Yeah i realized when you guys pointed it out that that lense is for mounting to the body so its focus starts from the CCD.
When you mean focal length you mean how large around it is? the 37mm is big at the body then goes more to a point. The 52mm is smaller at the body and gets larger at the front where the filters fit on. I dont want the larger front, i want it to tapper down smaller in the front so its not blocking the AIAF and the viewfinder. Am i right about this? the picture of the 37mm adapter looks as if it gets smaller at the front. Is this picture in the auction not right?
If i buy the 37mm adapter for my camera can i just search 37 mm filters and they will fit? since the adapter is "A70 to 73mm" right?

The 37mm on the adapter is the filter thread diameter - i.e. the distance across the body of the filters that screw into it. A bigger filter thread mean wider (larger) filters and/or lens hoods.
The 37mm on the lens is the focal length, which is related to the strength of the magnification. I won't try to explain how to calculate it (if you want to read more, try //en.wikipedia.org/wiki/Focal_length). A small focal length means a less magnification which gives a wide-angle view; a large focal length means large magnification which means a narrow-angle view (i.e. telephoto).
It would be possible to have two lenses that from the outside looked the same, and had the same filter thread diameter - but different focal lengths, because the arrangement of the glass inside the body of the lens was different.
To pick a concrete example: I have a 50mm f-1.4 lens. This means that the focal length is 50mm which is a "normal" view on a 35mm camera (47 degree view) or slightly telephoto on my DSLR. But the filter thread diameter is 55mm. If I went to the shop and bought a 50mm Hoya filter, it wouldn't fit.
I also have a 18-70mm lens (zoom lens). On this one the focal length goes from 18mm (moderately wide-angle, 76 degree view) to 70mm (telephoto, but only mildly so - 23 degree view). The filter thread on this one is 55mm too.
Hope that helps...

If you were to guess the size of this lense what would it be? 37mm? 52mm? or what? so im clear on how to find the lenses to fit my camera.

You need a lens extension kit that is dedicated to the Powershot range.
You cannot fit any lens other than a Powershot specific lens adaptor to your camera.
You may be able to fit filters to your lens (with the appropriate adaptor), in which case you need to match up the diameters of your lens/lens adaptor and the filter you want (eg 52mm diameter lens thread = 52mm diameter filter thread).
Repeat: you cannot fit any lens to your camera other than a Powershot specific lens adaptor. Buzzrock gave you a link to an adaptor kit that is Powershot specific and would work with your camera.

His links were to the big lense that block the view though, this is what im trying to avoid. I think i have it figured out now doing more reading.
You guys kinda confused me, at the begining. Going back and rereading the replys, this is the main one that i understand.

It will FIT but it wont WORK. My post is not clear on what i was looking for. I wasnt sure what all the 37mm and 52 and all that means. I understand now. I could buy the 37mm adapter and then fit on any 37mm lense but they may not WORK still screwing together but not having the right focal length.

They won't even screw together. The screw mount on an SLR camera is not the same as the threads at the end of an adapter. |

No it won't fit and it won't work.
The adapter slips on the end of your existing lens and allows you to have 37mm diameter filters on the front of your existing fixes lens.
You may be able to find a x2 additional lens or a x0.47 wide angle with a matching 37mm rear thread, but to be honest they are usually poor quality and will not give good results.
The lens you have linked to is not a 37mm rear thread, it has a M42 rear thread which is the pentax standard. It is for mounting on an old pentax SLR.
Hope that helps
Recommendation: don't but an add on lens for your p&s - you will not be satisfied with the results. I had one for my Canon S50 and sold it after the first set of images.

I know I was new to this game once, but please tell me this is a wind-up. Its the best laugh I have had in ages. I particularly like how the guy will not be happy until you can tell him it will work.
FYI, the only lens that will fit this camera is the Tamrom 28-75mm F2.8, make sure you get the one with the Canon mount.

If a Tamron 28-75 would fit, wouldn't the Tamron 28-200 I'm trying to sell fit too?
If not, maybe I could file down the mount to make it fit a 37.5 mm thread.
