basically ive got the canon lens adapter(LAH-DC20 58mm) and im going to buy a hoya polarizing filter:

1. will this filter screw directly onto the adapter?

now if i wanted to use my teleconverter(TC-DC58B) with the filter, is there a thread on the front side of the filter that will allow the teleconverter to screw in?
or if there is no thread, then is there some ring that i can get that will stick on to the front of the filter and allow me to get the teleconverter on

thanks

The Hoya filters are threaded front and back so that you can stack them. However, I'm not sure how effective it would be to have a teleconverter on the front of a polariser - I suspect that the TC would affect the polarisation of the light, rendering the polariser partially or completely inefective.

Does the TC-DC58B have a front filter thread?

The canon lens has no front filters. Not sure how it would work with the filter between the lenses.

well thanks for the replys

i imagine that there is no ring/adapter that can attach on the front of the teleconverter to give it a thread? ie thread|filter lens|(something)|teleconverter|

And, you can't put the filters behind the converter...they must go in front...

But, just a little bit of practical shooting advice...while you'll find yourself using a polarizer with a wide angle converter a lot, you will find that a polarizer is almost never needed with a telephoto converter...if fact...a polarizer will rob you of light that you'll most likely need when shooting at extreme tele...

alrighty
thanks for clearing that up

Just so as i understand what you guys have been on about.... (bit confused)

If I get the lens adaptor, I can attach a filter (whatever type) to it directly.... right?

Then if I want to add a teleconverter, I would take the filter off, and put the teleconverter directly on the adaptor.... right?

Could I then, if I had one big enough, add a filter to the front of the teleconverter??

What I'd like to do:

1. Get the Lens Adapter
2. Get a UV Filter to protect the lens itself
3. Get a Polarizer for when I need it
4. Get a Tele Converter for when I need it.

I'm in the UK, can you suggest (apart from Canon own) the best type to get for options 1, 2, 3 & 4.
I see some people use 58mm, and others 52mm.... I'm confused, I thought it was one size?
Can you use a Polariser as well as a UV together??

Cheers for any help offered.

If you search e-bay you will find other options for the adaptors.

The 58mm tube comes out from the camera and then gets large at the end where the threads are. I would guess these people got the 58mm because they may get the canon DC58B teleconverter lens it uses the 58mm threads.

Some want the raynox teleconverter lens wich has the option to use filters at the end. They use a 52mm tube wich starts large near the camera then it tapers down to 52mm threads.

Think of it this way. A round tube, one side has the canon S2 conector, the other end has 52mm threads or 58mm threads depending on wich you get.

I think 52mm and 58 are the 2 common sizes. I seem to see more of these 2 sizes then any other so i think this is why they chose these 2.

The canon telephoto lens does not use any threads at the end so you cant put any filters on it.

Its hard to say what is best because im not sure what your planning to do with your camera. I would get the canon telephoto and the canon tube with maybe a 58mm UV & a polarizer. Thats about all you really need.

If you wanted the raynox lens get the 52mm raynox tube and a 52mm UV filter. If you want to put a polarizer or somthing at the end of the raynox lens get the filters that fits it.

I dont see a need for filters at the end of a telephoto lens but you may. When you remove the teleconverter put the UV filters on to keep the stock lens clean and scratch free. Also pickup a pinch clip lens cap to fit the 58mm or 52mm tube because if you leave the tube on the camera the new lens caps will fit on tight and stay on wether the camera is on or off.

Thanx BowerR64

Very clearly put!!

I'd like to get the adaptor mainly so I can use a UV filter to protect the main lens, and possibly use the sunshade as well.
The polarizer would be useful for when I'm out near the lakes to stop reflection, and also for shooting through glass, as I have to sometimes at my sons TKD just to get a good shot of him.

The teleconverter woulkd be my later purchase as I haven't found a need for this yet.

So it looks like the Canon options would be best suited for my needs then.

Many thanks
