I'd like to purchase a Zoom doubler for my FZ20 but I can't justify buying the Panasonic product. The price is really out there!

Any Ideas?

i assume you're talking about a teleconverter... there are a number of good ones available in the 1.4-1.7x range. i have an Olympus TCON-14B which is 1.45x and cost me a bit over $100 on ebay. retail is about $175, i think. if you don't mind using stepdown rings to use a 55mm thread, you can use the Olympus TCON-17, which is 1.7 x, and can be had for between $80 and $100. it's not as well made, IMO, as the 14B, and it's a bit "softer" and more susceptible to CA, but it'slighter andoffers a little more "pull". there are others available as well in the $100-$200 range. here's a link to a site with some useful information...the site is written for the FZ10, but all the lenses will fit the '20 with an adapter.

I have a Canon 55mm 1.4x. It is often listed for the Panasonic but don't buy it. It just is not sharp.

I would love to add one of these to my FZ 30 and I am liking what I've read about the tcon 17. I am a bit hesitant tho, because of the experience I had with my minolta 7i. After I added the tele converter which was made for this camera by Minolta, the camera took on a whole new shape, and handling characteristics were...ugh, indescribeable. (I must say tho the lense produced chrystal clear shots!) The lense could only be used after downloading software into the camera, it had to have the barrel fully extended, locked in macro position, and the only focal options were zoom at max, period. It only boosted the zoom to 10X. It was a pain to put on and take off and I had to be V E R Y careful because it weighed a ton, and I had to support it at all times with my hand under the barrel where it joined the normal lense. A N D it cost like a KINGS ransom. Here's a shot of the beast with the add on. See what I mean? How'd you like to lug this around? So my question is, how versatile is the 30 with an add on? Can you use the zoom in and out with it on? (could not with the 7i) Is it structurally sound, how careful do you have to be supporting the extra weight? Many thanks if you can shed some light here. Best regsrds,

With all my other FZ cameras I have used a number of add on lenses. I got fed up with fooling with adapters and big lenses that made the cameras.....well hard to use. Now the FZ30 has solved the adapter problem with the simple 55mm thread and just yesterday I read where they now have released two completely new lenses specifically for the FZ30. A W/A and a telephoto. Both are said to be smaller and lighter. I hate to think what the price will be? BUT I will wait! Frankly there is plenty to do with this camera just as it comes out of the box. I sort of solved the W/A problem by carrying my Sony W-7+the W/A attachment in my pocket. Something you can not do with a big screw on W/A lens for the FZ30. Since Imagestabilization is not all that practical with add on lenses anyway, I might just keep my $$$??

squirl033 Oct 25, 2005 5:25 PM

the TCON-17 is a relatively small, lightweight (~9.5 oz or thereabouts) converter. it's a good deal smallerand much lighter than the TCON-14B which i have (and which i bought to avoid having to use steprings), but i believe it is not quite as sharp, and is just a teensy bit more prone to chromatic aberration (purple fringing). The TCON17 is less than $100, usually, so it's not a budget buster. if you shop around, you can probably get one for around $80.

for most uses, it will do very well. it's simple to use... no special settings required, no hassles. just thread onto the front of your lens and it's ready to go. it's reasonably sturdy, from what i can tell,since it will screw onto your adapter,not the lens barrel itself like your Minolta. it will definitely NOT require any changes in software, though it will definitely add some weight and bulk to your FZ30,and youwill probablywant to keep a hand under thejointbetween the converter and lenswhen shooting and carrying anyway, just because the camera will balance better that way.

i can't speak for the FZ30, since i have a '20, but with mine, the zoom is fully functional with the converter on, and i can't imagine Panasonic would change that for their new flagship model.you will get vignetting below about 4-6x, but then, you don't put a converter like this on in the first place unless your prime lens doesn't have enoughpull, so there'd be no point in using it at low zoom settings.





telecom Oct 26, 2005 9:55 AM

Yes that's what I'mmeant. You mention the TCONs by Olympus. I'm wondering what is the sizeof the converter opening. On the FZ20 the lense size is 72mm. Is the TCON also 72mm?

telecom Oct 26, 2005 9:58 AM

Man that looks very awkward. I hope that teleconvertors aren't all like this. It looks like you would need a tripod for the camera as well as the converter.

Looking at your picture ... with digital photography we've come a long way. You would never have been to able to explain what this picture shows.

normc Oct 26, 2005 12:06 PM

Take a look at: http://panasonic.co.jp/pavc/global/l...rsionlens.html

This shows what Panasonic has planned for the FZ30 for add on lenses. Having some experience, Canon Pro90IS, Olympus C-2100UZ, Panasonic FZ1,FZ10,FZ20 and FZ30 and starting with the Olympus B-300 I have screwed a batch of add on lenses to all of them.

They were all good cameas with the C-2100UZ being outstanding. (if I could buy one new, I would) Maybe some can do it but trying to hand hold at above 10x to 12x zoom is difficult to say the very least. I got a lot of hand held photos at those extemes but never a really good keeper. So if you read the info on the Panasonic site you can see that their new lenses for the FZ30 are smaller and lighter. In other words they are addressing the problem, These are not the same lenses that went on the FZ20's. For myself I only want lenses that are designed for this camera

the TCON-14B has 62mm threads, and most folks who use aftermarket teleconverters have some sort of lens adapter installed, like the Phayee, which i have, or a Pemaraal or Raynox. the Phayee has 62mm threads as well, so the TCON-14B screws right on. the FZ30 has 55mm threads already on the lens (an oversight on the FZ20 that Panasonic wisely corrected with the '30), so a TCON-17 would screw directly to the lens itself.

the objective lens diamter of the TCON-14B is 86mm, and i believe it's about 77m on the TCON-17, but the latter has no front threads.



squirl033 Oct 26, 2005 6:44 PM

Normc, that DWM-LT55 teleconverter looks suspiciously like the TCON-17...i'd not be surprised if this is just an Oly lens remarked for the Lumix line. :?

normc Oct 26, 2005 7:11 PM

Could be? But we can bet the price will not be the same. The only two lenses I now have are a Canon 55mm 1.4x and the Olympus TCON 0.7x The Canon is small but the results are terrible....forget it. I have been fooling with the Olympus W/A. When I went to screw it on to the FZ30, I stopped as it appeared that it would touch the camera lens. I then fashioned a spacer from an old close up lens and that seems to work OK until I started to compare the photos of the same scene with another camera. This lens just will not do it for me. I am almost to the point where the idea of having one camera that will go from 24mm or 26mm to over 400mm plus and still produce outstanding photography might be a little nutty?

I also learned from the earlier FZ cameras that the fit of the telephoto with respect to the camera lens is critical to how well it will perform. I no longer have a 1.7x so I can not comment on using it with a FZ30

yeah, i'd heard the TL-55 was not a good lens... too 'soft', and a good deal of CA in high contrast shots. if you want a 55mm tcon, i think the TCON-17 would be the best bet.

i don't know about trying to mount converters directly on lenses, as i have a Phayee adapter on my FZ20, and that positions the UV filter (which stays on the camera at all times) about 1/16" in front of the maximum forward extension of the lens. i just screw my TCON-14B onto the UV filter, and i'm good to go. that gives me a total range of 36mm to about 620mm, which covers about anything i'm likely to need. i find i don't need an actual "wide angle" lens, as the 36mm setting on the camera is sufficient for my needs.

The WCON07 on the FZ30 causes a blur in the middle of the image. The Best WA on the FZ30 is the HD6600 -55. It will be out in a few days. I have a DCR6600 same lens in a 52mm mount in a glue up mounting to simulate the results.

lovelife,

In your gallery http://lovelife.smugmug.com/gallery/804122 there are tho shots with virtually the same angle of view (shot nr.5 and nr.7) while according to their descriptions, it should not be the same.

The shot nr.5 is described as 24,5 mm focal length (taken with WCON-07) and shot nr.7 is described as 28 mm focal length (taken using WCON-08B).

I have closely examined both shots number 5 and number 7 and they were taken within a short time frame of each other on a tripod with quick release mount. If you are referring to the cameras exif information Focal Length: 7.4mm (35mm) for both pictures that is correct. The camera is not aware of different add-on lenses in front only it's internal settings. WCON07 is .7X x 35mm or 24.5mm; the WCON08B is .8X x 35mm or 28mm, the pictures, close in perspective, were recorded with the two lenses as stated.

KENNETHD Nov 8, 2005 12:52 AM

I choked when I saw the price of the Panasonic 1.7X tele, but bought'er anyway. Why? Well, Mainly because they built such a great camera for me (FZ 30) at such a good price, I just said thank you with my wallet, to them for that. I'm happy to say I have not regretted it! I'll post some shots, I believe they hit a solid home run with their tele, just like they did with the FZ 30. Shot quite a bit with it this week end and yes yes, yes. It works as advertised, for sure. Best regards,

lovelife,

I know, that the camera isn't aware of any additional lens attached to main lens. I did not looked at exif info.

Instead, I just visually compared the two shots. I attach the crop of sides of your pictures. The left one is the 5th shot (FZ30 with WCON-07), and right of it, the 7th shot (FZ30 with WCON-08B). Doesn't they look like they was taken with exactly the same angle of view? (focal length).

I think, there should be a visible difference between 24,5 and 28 mm focal length, like it can be seen on a second attached picture, where I tried to simulate this difference by marking the 28mm focal length picture by a yellow rectangle, and where the whole picture shows the wider angle of view (24,5mm). This marking is just my quick estimation, I didn't computed it exactly, but it shows, how approximately these two shots should differ.

There is something strange with these pictures.. I can't tell how it is possible. I even can not verify it, because I don't have the WCON-08B nor the FZ30.

HELP!! I recently purchased a Panasonic FZ30, along with converter lenses, telephoto and wide angle...(not having a clue as how to use them)...When they arrived, the lenses didn't screw onto the camera and were sent back.....The store was gracious enough to send a more expensive pair back in a larger 58mm size, the others were either 55mm or 52mm, i don't remember which. These are very expensive lenses, Crystal Optics, Professional, but it doesn't matter what they cost if I can't use them...(and they cost $600, including the filters which ALSO don't fit the camera)...Any suggestions?...Is there an adaptor that might help them fit......The stores Vet Tech said that I had to use them with the lens hood and I about turned myself upside down trying to have that occur. I sure hope I didn't scratch the Leica lens on the darn camera now as I was trying to screw lens to lens......sigh

I'm so frustrated I could cry at this point.......know what I mean?



Thanks alot for your help!

Shelley,

You are dealing with people who have sold you the Brooklyn Bridge for too much money, unknown add-on lenses they are unscrupulous who are clueless. . If you cannot get your money back report them to the better business bureau. Known items that work on the FZ30 are Raynox DCR2020pro 2.2x telephoto 62mm mount (requires 55-62mm step-up ring)$210.00, Olympus Tcon14B 1.45x telephoto 62mm mount (requires a 55-62mm step up ring)$180.00, Olympus TCON17 1.7x telephoto 55mm mount (does not require a ring) $110.00, Olympus Wcon08B .8X wide-angle 62mm mount (requires a 55-62mm step-up ring)$150.00 and Raynox DCR6600 –55 .66x wide-angle 55mm mount (does not require a ring) $110.00. These areexcellent performers and you can see by the prices that you were had. If you cannot get your money back you will have to calm down and describe each piece. the name, the mm mount at the rear of the lens and the type of magnification. Forget the lens hood BS you cannot use it with these lenses. What you need are rings that will convert the lenses to fit the 55mm female threads on the camera. This will guarantee the lenses to fit the camera not the quality of the results.

Money does not indicate quality next time ask the forum.Here are examples of what you can expect with these lenses.

Save you breath I will redo the shots but expect the same results. Remember that the WCOn07 is failing to perform correctly on the FZ30 the blur spot in the center.
