2x converter 953

heh all i just got hold of a 2x converter that cost $15 aud. had to buy a converter ring which was 43-46 that cost 11 and now i have a 2x converter. i have some problems however and that is the fact that at full zoom it has somewhat tunnel vision and on shots with little movement the corners are very blury. anyway does anyone else have this problem. apart from that for a cheap converter steals very little light. (on same frame f11 as opposed to f9.6) not bad really. anyways talk to you all later.

Justin

I would never offer that low cause i would feel rude. anyways heh.

I also have to keep my zoom from 2x-10x or you can see the outer edges of the lense.

I guess with the iris closed down, you can pull in some good footage at the beach. :-))

I had a dad like that, bless his soul.

Softening and bluring of the edges are signatures of poor lens. Good lens are always sharp throughout, but probably in the range of a few thousand dollars.

Use the tele lens only at the long end of the tele of the camera. That way, you lessen the edge effects. And use a small apperture for the much reduced depth-of-field when zoomed in and with the convertor, somehting like f8 to f16, which will help maintain sharper images. However, that'll mean shooting in broad daylight.

Justin,
What does the picture quality look like beyond the effective zoom ranges on your MX? For example, if you zoom the MX from 5X to 10X (when multipled gives you 10x to 20x), are the pictures usable?

I've tried three tele conversion lenses with my MX300:

Genuine Pana 1.4x 43mm thread VW-LT4314ME(http://www.panasonic.com.au/ecam/acc.html)
Has full zoom through (i.e. no vignetting) and has no discernable softening or chromatic abberations on the edge of the image. It's the best, but it's not 2x.

Raynox 2020(http://www.raynox.co.jp/english/vide.../dvr2020eg.htm).
It's 2x with a 37 mm thread so you have to step up to the 43 mm on the MX300. You need to use it or or near full zoom, but it does give quite acceptable results - with some softening on the edge, and also some chromatic abberation on the edge in high contrast situations. I use it a lot for wildlife shots.

Tiffen Megaplus 2x 43mm thread (http://www.photo.net/equipment/digit...eras/megaplus/)
I had high hopes for this as the thread size matches the MX300, but it has much worse softening and chromatic abberations on the edge of the image than the Raynox. Most ill suited to the MX300.

hi all
the picture is quite good except for what i said. If shooting at an animal or an object it might be alright because it doesn't matter so much about the background and you probably wouldn't notice it. but shooting a landscape with detail around the edges that is all part of the shot might be a little dissapointing. i'm pretty sure i know what the problem is but its a little hard to explain and i don't believe it is a depth of field problem. with this cam the depth of field has never been an issue wherever the aperture is. The background usually always remains sharp at 16 or even 1.6. I am guessing that it is to do with the size of the ccds being so small. i don't think i have explained the problem too well and will probably get some grabs some time to show you all what i mean and the improvement on zoom it makes. maybe sometime over the next week so look out.

Kodak made a 43mm 2X telephoto for their digital still cameras that might be a good buy (<$50). I have the companion wide angle which is a pretty good lens. Here is a site with some examples of this lens with a Panasonic 601. Seems to have some chromatic aberration in the one still but that could be the camera.
