Pl tell -Which is best (optically) wide and Teleconverter for Fuji HS30? This question may have been asked but I could not find answer.

I want to take Bird and wild life pics. For that purpose I need maximum tele and wide for landscapes. I know 24mm is enough still I want more.

On Ebay , Amzon many brands available, which to choose. Or I should buy Nikon Coolpix 510 which has built in 1000mm Tele. I know there is little deterioration in quality with converters but good makes does not make big difference much.

--Forget about any tele converters with natvie 720mm it is more than you ever can use and stop dreaming about taking pictures at 1400mm its no going to happen. Learn how to get closer. As far as wide convererts since Fuji has 58mm tread size get a Century 0.55 wide and fisheye at about $150 it is best you can get and dual use as well since it dose fisheye as well. Century make best front mounted converters on this planet and most are way over $1000 but this one is acctualy with in a reach for Joe Shmo.
This converter will get you about 16mm at wide end.

While that may be true for 2x TCs, Fuji HS camera do very well with some Sony, Nikon and Canon 1.5x and 1.7x TCs. It happened, still happens, and will continue to happen. Sometimes getting closer isn't an option, and there are reasons why a 2x TC could be useful for reasons other than creating photos, like turning the HS cameras into powerful spotting scopes.

Why not provide links to real prices from real dealers. The ones that I've found (Calumet and Adorama) have this dual adapter for $279 and $299. Is it your habit to quote used eBay or Craig's List prices without identifying them as such? I suspect that even if Century produces fine lenses, this one will be little better than a novelty for most people, and I'll be surprised if you actually know how well it will work on the HS cameras.

Many USA corportations make far more expensive precision equipment for the gov't and military, yet sell crappy products to the public. BTW, the real Joe says that his name is spelled "Schmo".
 
Bill, on doing searches on the Raynox 2025 I find both positive and negative reviews for it, is it reasonably sharp in the middle of the frame? I cant get over the fact that even Raynox states that its resolution is only 260 lines per mm, aren't these 16 MP sensors capable of over 2000 lines per mm? So this TC, although giving 2.2x more reach theoretically, removes almost 90% of the resolution?

Thanks for the link! That guy used to be a Nikon Talk forum regular back during the good old days when the Nikon Coolpix series ruled the roost for compact cameras and he performed a bunch of tests on their teleconverters and other accessories. This is going back 10+ years (I've been here since year 2000 and he was there from before.)

You got it. But for the first time ever, the original Raynox 2.2x TCs seem to have vanished. What I recall are 2020 and 2025 models, but now B&H has a 2.2x HD-2200PRO-LE that only claims a central resolving power of 200 lpmm. And you can pretty much be sure that corner performance is much worse. Take an old camera that it might have been used with, the Canon Pro90 IS. It had a pretty large 1/1.8" 2.6mp sensor. Its dimensions from DPR's sensor size page is about 7.2mm x 5.3mm. If it had photosites laid out matching Raynox's 200 lpmm, it would be a 1440x1060 sensor, and this is equal to only 1.5mp. So even for that old 2.6mp camera, the 2.2x TC doesn't have enough resolution to satisfy that modest 2.6mp sensor.

I guess that its owners wouldn't be too upset because even though resolution would be lost, the 2.2x magnification produces an image with an area 4.8 times larger, so the photographers would probably see more detail with the TC than without it. But put that TC on a higher resolution camera like the HS20 that crams 16 million pixels onto a smaller 1/2" sensor and that TC would be a joke. It would be silly even if it was shot in 8mp mode. And that's exactly what I found when I used it with the HS10 with its even smaller 10mp 1/2.3" sensor. That TC is huge and looks pretty impressive, but it's hard to believe that it's used or useful for much other than low resolution videos. I'd consider buying one of those Raynox bazookas if it was offered as a P. T. Barnum Commemorative Model.

I posted that link a couple of days ago along with this one below, and there was also the lens reversal page. You no seeum? :)

No, it didn't know up on my end until now :-( I see it now though! And here's one more:

http://www.cs.mtu.edu/~shene/DigiCam/User-Guide/FZ-30/Converters/Lenses/Telephoto.html

That Nikon 1.7x seems to be the highest quality but that thing is a beast of a lens and too heavy for my tastes.

I find the two Sony TC more interesting, but I cant seem to find them anywhere, whenever I click on a link that says it's one of them, it ends up being a noname TC being sold for 70-99 dollars.

Bill, it sounds like one of those lenses that although it makes the image appear larger, you actually see less detail than not having it on the camera. A nice converter lens if you're into threading a paperweight at the end of the camera :-)

sony is good but canon 58A is better at least par with nikon ... sometime i use double converter and the result isn't bad until 50%-60% crop.

I found a bunch of them too, but it's available from a few dealers. I can't vouch for them though. East Coast Shipping has it for $133.19 (Free Shipping) and aztekcomputers has a refurbished DH1758 for $104.50 and probably has a shipping charge.

I'm not surprised that it's hard to find since B&H and Sony's website say that it's discontinued. The beefy version seems to be everywhere . I found a blogger's hands-on review that compares the HS10 with the HS20, and he managed to get both of Sony's 1758 TCs, and he wrote that the smaller DH1758 produced better results, just as I found. He didn't mention the awful CA of the larger HG1758, but that's probably because some scenes have a lot of it and others don't, and I don't think that he used it very much anyway. The HS20 is a keeper for him, but he pointed out several aspects of the HS10 that he prefers.

Thanks, Bill, I dont know if the second link still has it as they only had one in stock and when I did a mock order they said none were in stock. So I clicked on the first link, it seems to have it, and they both take Pay Pal, which is great :-)

I read somewhere that the magnification power of teleconverters depends on which size sensor is being used. For example the cheap 2x teleconverter I got as part of a bundle was made for a 1/3" sensor so for the 1/2" sensor of the HS20 it only provides 1.5x magnification. The Sony TC that we were discussing was made for the Sony H1, which is a 1/2.5" format sensor...... I haven't done the calculations yet, but it looks like it should also work out to 1.5x with the HS20, Bill may be able to confirm that.

I was right.....1.526175x so just very slightly more magnification than the el cheapo one I have but probably much higher resolving power lol. 1.5x times the actual tele focal length of the HS20/30 (680.4mm) brings us to just over 1000mm (1020.6mm I think.)

For future reference, to calculate magnifying power with a specific sensor, divide the length of the diagonal of the sensor the converter was made for by the length of the diagonal of the sensor of the camera it's being used with multipled by the specified power of the teleconverter.

Use this table:

I cant tell which size sensor that Raynox was made for, but all the compatible equipment listed for it on Raynox's website are camcorders with between 1/3" and 1/4.7" size sensors; likely it not only does not provide the specified resolution of the camera, but not even the specified magnification of the converter!

No. That's the effect that any FF lens gives you when it's used on an APS sensor camera, the appearance of more "reach", but there's no true magnification involved. Condider how you can take a lens and hold it so that it projects an image on a blank piece of white paper if it's held at the right distance from the paper. Now put a TC on the lens and do the same thing. If the paper has two rectangles drawn on it corresponding to the sizes of two different sensors, if you shift the paper so that one rectangle lies within the image circle and then shift it so the other rectangle lies within it, the magnification won't change. And the ratio of the magnifications using the TC and not using the TC will be the same. Only the size of the rectangle/sensor changes, and that would cause the same kind of different "reach" as you get when you compare images created using the same lens with different size sensors. The TC provides the same magnification, and it doesn't have any way of knowing the size of the sensor that its image is projected on. The magnification of Sony's 1.7x 1758 TC is the same when it's used on an HS20 as when it's used on an HS10 that has a smaller sensor.
 
Thanks, Bill, that's a relief! So that means that no matter which size sensor is used with whichever teleconverter, the magnification will always be the same on top of the zoom of the camera lens?

Because in my head I was starting to think that Nikon's 1.5x and 1.7x converters may have been made larger because they were specifically made for Nikon's high end Coolpix cameras that back then used 2/3" sensors so in theory they should offer more magnification for the smaller sensors used by today's bridge zooms. The 1.5x would be around 2.1x and the 1.7x converter would be around 2.34x with the HS20/30 if that was the case.
