Well new to me at least. This one is in great condition as the lettering will show. I plan on doing comparison photos with this one and my one touch lens in the same focal length. Note to self....always clean a new acquisition before shooting with it...Now I gotta clean the sensor!!!!!ARRRGH!!! Anyway...I'll soon see the difference between close focusing and macro focusing. LOL

Both are Kirons as the serial numbers both start with 22.

What is the different between this two lenses, one touch and two touch?
I am a beginner and just bought my first DSRL a Pentax K-x
Can I use both lenses with Pentax K-x?
Witch one will be more easy to use for a beginner?

At the moment a have the kit lens DAL 18-55, i am not shure what is better the Pentax 50 - 200, or an old lens like Vivitar 75-205mm F3.8 ?
Is the sharpness nearly the same or maybe the Vivitar better?
Sorry for so many questions on my first qoute in this nice forum.

Thanks for some helpfull answers

sweeet! the close focusing is just like my 90-230 and its one sweet lens


edit: the clos focusing has two rings, for example on my 90-230 one for moving from 90-230 and the other to change the depth of field, closest being macro mode and furthest being telephoto mode (if I am correct, its been a week since ive used this one) allowing you to get macro mode at 90 and macro at 230, which is I believe something like 1:7 all the way to 1:2.5 wit mine, not sure about this one, but my math could be off. Its not stepped so its a smooth transition between macro focus so you can really find that sweet spot and not have to move around/get right up on things. You can even get a nice macro far focus in between the 90(or 75 in this case) and the macro setting, IE. comes in handy when you're photographing something and quickly catch something small relatively close to you, you can focus it down a tad to get macro and not have to reposition yourself. The area smoothly transitioning to macro mode is a great and allows you much versatility in macro shooting to still get macro shots from good distance away.

hope this makes sense, kinda late and probably not worded the best

both can be used on ur kx by the way, I have mine in M42 mount so i have to use an adapter, but vivitar is much like tamron and sigma who man. their lenses for many mounts.

to me, the close focusing is one of the most versatile lenses Ive ever seen with its many macro capabilities and telephoto zoom. The vivivtar macro focus is more or less a telephoto zoom that allows focusing closer to the glass, and does not utilize a special ring to control macro amount/distance to focus

so which will be better for use?
the close Focus with two ring, or the other smaller one with one ring?
which one is technical the better one?
how much was the price difference when they came out?
which one came out first, in what year?

thanks for your help!

You can always go here for the age of a lens and other details...
https://spreadsheets.google.com/ccc?...IWts9UO#gid=63

Or here to use the serial number of a Vivitar brand lens to find it's age.....
http://www.robertstech.com/vivitar.htm#serialno

As to which is better ...the jury is still out on that one...the one touch is a bit easier to use but the two touch has a bit better close focus IQ. Either one will do a great job, really.

Oh yeah their ages...the Two touch was made in 1979 and the One touch was made in 1981.
