Hi, has anybody experience witha Nikon 5t-lens on FZ20?

What results can I get, is the 6t better? What is the distance to

the object?

In a few days, I get my Phayee-adapter.

greetings

Klaus

Either will work with your Phayee, as you probably know the 6t is double the power of the 5t; if you consider more power "better" then yes the 6t is "better" (and the Raynox DCR even more "better"). With high quality "better" is so subjective. I have seen LOTS of samples of what the 6t can do posted here and none of the 5t that I can recall. I like the 6t and have even stacked two 6t's for more power. I suppose it depends on if you have a specific purpose in mind that the lower mag of the 5t is suited to - or if you just want to improve your macro capability.

F=1/d where F is the focus distance in metersand d is the diopter power of lens. Therefore, the 5t being a 1.5 diopter lens will focus at 1/1.5=.67m=~24". The 6t being 2.9 diopter will focus at ~12".

Thanks all for the informations.

Iam such a newbie in Macro-Lenses:?

The distances 24" / 12", are they on full 12x zoom?

greetings

Yes. At lower zooms the focus distance is not as critical or fixed although these are still about what to expect. As zoom is increased, the depth of field decreases and the focus distance becomes more exact. I finda +3 diopter (ex, nikon 6t) to be the more useful closeup lens. Not only is it more powerful but 12", IMO, is a better distance to get a 'feel' for the subject. 24" away just seems a little too far. I have both a +3 (oly b-macro) and a +1.5 (nikon 3t) and that really is the best way to go. They can be stacked for a +4.5 diopter (focus distance about 9"). I also have a raynox dcr250 which is an excellent +8 diopter lens that focuses at about 5" but has an extremely shallow dof.

klaus,
I agree with fmoore, take the 6T first.
It is more fun. I was disappointed by the 1,5 diopt. lenses at first, I wanted to be closer to the objects - bugs. But it is a hard job to focus with more than 6 diopt. and get the right light for your shots.
Look at my thread to see the minimal area to cover with you shots.

This distances measured here were, from the front lens to the objects - some lenses are very long...
5T like the elpro VIIb covers only half the field compared to the macro zoom of the FZ5.
The 6T like the mcon40 - bmacro covers a field up to 2,5 cm!
Liebe Grüße
sven
