The basic lens is equiv. to 420mm (in 35mm format). If you tack on a Panasonic teleconverter (1.7X, I think) it brings the lens to over 700mm (in 35mm format equiv.). That should be enuf for most things.

 

From what I've seen & heard, the Panasonic teleconverters have pretty good optical quality & won't change the max f-stop of the lens -- in other words, the max f/stop at telephoto of f/3.7 will not be any smaller if you put the teleconverter on. It won't be the same as a high quality really long high quality OEM telephoto, but those will be more cost than the V-Lux, aux. teleconverters, your camera bag, all your memory cards and your PC, too.

I used to believe that when using a 1.7X teleophoto converter, you should have multiplied by 1.7x the maximum aperture too.

Am I wrong?:confused:

What are you trying to shoot?

These are some of what I took. These are generally what im trying to shoot, just with a telephoto.

See the zoom on it is fine enough for distince, but the optical zoom only goes so far. And the digital zoom doesn't have the quaality that i'm looking for.

Maurizio,

 

A fair question but this is not a true teleconvertor that would add distance between the lens and the sensor because the V-Lux has a fixed lens. Afaik it's a telephoto element that screws onto the front of teh lens so the maximum aperture may not be affected because, if it's wide enough, the telephoto element won't prevent much light from reaching the lens.

 

It's the same with the series of Elpro close-up attachments for R lenses.

I believe Pete is right. I know, on my Oly kit, the teleconverter I occasionally use adds a full f-stop to to the lens, but that mounts between the camera lens mount & the lens. Since I usually use zooms (which are pretty slow to begin with), its not exactly a low-light solution. I did an experiment with my Leica & a Panasonic wide angle teleconverter (dropping the field view to a 35mm-equiv. of about 24mm). There was no change in the internal light meter reading. I would expect the tele teleconverter to be the same in terms of zero effect on f-stop.

I had V-lux, but sold it quickly. Way too small sensor (CCD 1:1,8") was not satisfying me at all due to bad noise. Lens had extremely wide range, up to 420 mm telephoto. I don't think, that extending that is reasonable. Despite of OIS, I had many unsharp images in the longest end.

Well, that's what tripods are for. OIS only works up to a point; it doesn't perform miracles. If I had one of them, I'd only use it with a tripod or monopod or carefully braced on something solid.

 

BTW: if you're shooting birds or other wildlife, even 420mm can feel a bit short.

Well the newer FZ's are pretty impressive from what I have seen. Havent had a chance to play anywhere away from the sales desk, but I understand they are making ground with the AF, the processor, effective ISO all the time. Havent seen the VLux/FZ50 but I am more interested in the smaller ones for travel. If they release an upgrade to the VLux1, even the existing seems pretty good, and I dont think panasonic will reease a camera that is bad. At the Panasonic prices five hundred, six hundred bucks .... bit hard to see where you could go too wrong. Still think the G11 will be more robust and travel size friendly, more direct though the menus and electronic focus. Different beast, horses for courses. Personally I think all you need to know about the VLux (or Pana) is whether or not it delivers files equal to or better than the DLux4, and if it does then its features and versatility should sell it if you can manage with the size. Can't print A0+ from a six hundred dollar camera? Go back to photoshop and Qimage I guess.
