Teleconverters Any Good?

I will have the Lumix GX85 and Panasonic Lumix G X Vario PZ 45-175mm. If I want a longer reach, would a teleconverter work, such as the Panasonic 1.4x converter? How much would the image quality suffer?

Thanks.

The Panasonic DMW-TC14 1.4x teleconverter only fits the new 200/2.8 lens.

I don't know these specific items but the general situation is that TCs are only worth using if the bare lens is very high quality. The extra glass in a TC always has a detrimental effect; if the starting image is good enough that won't matter.

This link demonstrates the difference using Canon lenses but the effect is universal http://www.bobatkins.com/photography/tutorials/tc3.html

Re: Teleconverters Any Good?

Apart from the quality loss you lose one stop of light with a 1.4x TC so f/5.6 becomes f/8, for example.

Get a Panasonic 100-300mm MkII.

Re: Teleconverters Any Good?

IMHO, teleconverters are not worth their money with current cameras that have 24 or more megapixel sensors. I have a Keiko x2 TC, coupled it with a very high grade telelens (Minolta AF 80-200 F2.8 APO HS G), but the result was hardly any better than just cropping the image. As an experiment I also combined it with a Minolta AF 500mm F8 Reflex, just to see the result: it was marginally better than just cropping the image.

To me, teleconverters are a relic from the film era, where enlarging afterwards was more cumbersome than today.

My advice would be: get a decent telelens.

How much is lens specific, here is always quality and light loss. However, that doesn't mean the shots will be terrible and TCs are certainly a more affordable option than a separate tele.

I've got great shots with my Canon 70-200 2.8 and a 2x Canon TC. Yes, a dedicated 400MM would have been sharper, bit also at least 1K for a lens I'd hardly use.

As Mark pointed out,(and ignored by all ...) that 1.4 conv does not work with your lens but only the 200mm (and possibly another one or two)

The reason is very simple :

the glass sticking out would hit the rear elements of your lens.

Not that I expect anyone to take note of this either...

Anyway, as a tip, ignore all the comments about how a certain converter works with a particular lens unless that is the exact converter and lens combo you want to use.

How can you determine if a TC works (fits) on a lens? Is there a universal measurement for M43 lenses? Would only Panasonic TCs work on Panasonic lenses?

You would read the manufacturers statement about the TC.  The Panasonic 1.4 and new 2.0 TCs will work only on Panasonics 200mm f2.8 and the soon to be available 50-200 f.28-4 and not on any Olympus lens.  The Olympus MC14 works only on the 40-150 f2.8 and the 300mm f4 and not on any Panasonic lens.  Both companies TCs have a protruding front element which will not fit into any other lenses.

I own 45-175 too. Great lens. But if you want extra reach, only front-attached TC would work.

I use Canon TC-58D, Olympus TCon-17 and couple more.

Well. Well. Well.

The internal 2x digital teleconverter is better.

But can't say this to those exotic TC from Fuji and Ricoh.

.....

Last word.

The second hand 100-300 is cheaper than those exotic TC.

If one think something someone says is not right, why don't explain the right one directly to the OP with right knowledge instead of flaming the other? Don't use "OP knows nothing, can not separate right or wrong" as the launching pad for attacking people. Rotten sub-ego should be kept to one own mind.

The front-attached TC likes the filter. You just screw it to your lens's filter thread.

The 45-175 thread is 52mm. The tc-58d has 58mm. You need the $5 to bind them together.

You will get the best results from a TC that is specifically designed for use with a particular lens. So, look on the maker's web site.

Even then, you will lose a stop or more of light just when you need it most.

You will lose that stop of light always. I don't know m43 lens prices, but with Canon, one pays an awful lot of money to get that light back when buying a long telephoto. the 1K figure I gave previously was matching the light loss of a TC. If one wants to match the lens' natural aperture as well, it would be 10 times that.

There are several factors in deciding to use a TC instead of buying a longer lens.

Clarity, cost, need and convenience are the main factors. Those will vary by person and manufacturer.

I've tried several of these front mounted tele-adapters I don't think one of them was good enough for modern video use. Certainly they're not good enough for stills.

This may change with Ultra expensive models, but I have no plans to try.

You should try Fuji TCL-X100.

What your condescending attitude is intentionally overlooking is that the title of the thread was a question, and people are politely answering.

The specific combination problem was already answered.

If the rest of the helpful replies offend you maybe just go to the next question.

Ehh! They 'work' . . .

But I don't like their image quality now, for digital, as much as I did for film. I suspect that the sensors (and possibly, lenses) of today's cameras have so much better resolving power than film, that the imperfections that the teleconverters introduce are more noticeable.  And the ones I've seen seem kind of pricey to me.

I think I would look for a good manual legacy tele film SLR lens and an m43s converter. with m43s, you would only be using the sharpest center portion of the SLR lens image anyway, and a fairly decent 200 or 300 mm lens (equiv of 400 to 600 in m43s) should be and an under $15 adapter should be relatively inexpensive and likely to cost less than the cost of a 'good' TC.

On what lens & body? Both of these have a big effect on how acceptable a TC is...

It may be that there are much better versions around than I've tried. I wouldn't be surprised, but the results I can get with budget telephoto lenses have made me loose all interest in something that increases the minimum focus distance and resolution of my lens drastically.
