TL-H43 telephoto zoom

Has anyone tried this with the HV20? I am specifically interested in knowing if there is ANY vignetting when the HV20 is wide-open (1.8 aperture)? There are reports that the TL43 (no H) does show some of the adapter at wide angle and you'd need to zoom the HV20 to zoom past it. Thats not going to work for me. I especially need to stay wide-open in order to keep the aperture at 1.8 for low-light shots (I'm using a 35mm adapter so every bit of light is precious).

Thanks!

I'm a bit confused.. you don't intend to use the wide angle lens with the 35mm adapter, do you?

I have use a Brevis and I own a different wide angle lens, but I don't use either at the same time.

Canon Tele-Converter TL-H43 1.7x

I am using Canon's TL-H43 1.7x with my HV20.

The TL-H43 also shows some of the adapter at wide angle.

It works very well at high zoom, but not at wide angle.

What I'm trying to do is use the H43 in order to not use the achromat on the adapter and possibly not need to zoom the HV20 as much. Right now I have to zoom the HV20 to 2.2 (with 1.8 being wide open) in order to frame the GC on the Brevis. I thought that by using this telephoto adapter (instead or with the achromat) I could then zoom out less on the HV20 (for backfocus) and therefore have a wider aperture and thus more light coming into the camera.

Thanks Maury, I was afraid of that... Oh well back to the drawing board then. I suppose the tolerances on the HV20 are too tight for ANY adapter to avoid being seen at wide zoom.

doesn't the tele adapter also move the minimum focus distance out by 1.7x as well? so using it instead of a macro type lense wouldn't be optimal... correct me if i'm wrong anyone.

Yes it does (3 cm for this adapter), but that works well for the Brevis as far as distance to the GC. Again, I had no idea this would work but I was willing to try anything to stop having to zoom the HV20 from 1.8 to 2.2. I think my next best bet is to find a larger archomat (82mm perhaps) but I may be trying to do something that just wont fly. I wish that lenses were removable on camcorders so that we could optimize for 35mm adapters.

You will need to verifty first if the TFH43 has front threads.. the wide angle sadly doesn't.

It doesn't (per the marketing info). I was ok with that though since the Brevis has tension screws to connect to the achromat (or this instead). I think what I need is a bigger achromat so that the GC is magnified larger such that the HV20 then doesnt need to be zoomed as much. I know the difference between 1.8 and 2.2 doesn't seem like much but for low-light situations that extra 66% of light would be nice to have!

Something else I've been considering is just using two achormats together inline. I was wondering how to figure out what size that would magnify the GC and would that be "too big" now for the wide open on the HV20. Maybe not....

Interesting... I didn't know they made clamps for one side of step-ups. This could prove useful if I can find a larger achromat. Thanks!

i should get my tl-h43 on tues, at which point i'll measure it's OD and probably order a clamp on step up so i can put a UV and or polarizer on it, although i might run the polarizer inbetween the tl and the cam, just have to wait and see

and here a movie zooming through with and without.

also i'm going to get a clamp on step up ring...probably this one, as the OD is 74.5mm as stated by the lense cap that is included.

Thanks Austin,

Wow seems like to me that only half the zoom range is usable to avoid vignetting. Although at the long end of the zoom it was nice to see twice as much. This defintely lets me know that I need to keep looking at other options.
