W/NW Sonnar Lenses

[furcafe]

Focus shift is an optical phenomenon, so independent of focusing method. So, yes it happens on SLRs or cameras w/live view, but unlike an RF, you can actually see it happening.

What about the famed focus shift? Is it real? Does it affect rangefinder lenses only or it also affects through the lens focusing lenses like on SLRs?

A few from my first outing with my LTM 85mm f/2 Nikkor-PC:

Michael and Miko, thanks for the responses to my question. So are you saying that all Sonnars have the same block diagram, made up of 5 elements in 3 groups? And the elements in all Sonnar lenses are the same shape? And there are no Sonnar lenses with focal lengths other than 50mm?

There's a the 40mm f2.8 Rollei-Sonnar and there are some Sonnars with longer focal lenghts (like 85mm, 135mm and even longer, mostly for medium and large format).

The classic 50mm 2.0 Sonnar design consists of 6 lenses in 3 groups and the 1.5 Sonnar of 7 lenses in 3 groups. The modern Zeiss-C Sonnar 50/1.5 is 6 lenses in 4 groups (although one air space is a so called air-lens; if you would count this as a lens element it would be again 7 lenses in 3 groups)
Most 50mm Sonnars should follow this design (like the Jupiters, Canons and Nikkors) but well, I'm no expert and I don't know how all the different 50mm Sonnar diagrams look like 😉

I know that some Sonnars with other focal lenghts then 50mm differ in their diagrams from the 6L/3G or 7L/3G rule.

I confess to having a weakness for Tessar and Tessar-related lenses (like the Leica Elmar). Here's another one from a Carl Zeiss Tessar 40/3.5:

i thought he asked for sonnar shots...?

Me too. Nothing wrong with Tessar lenses but let's keep this one clean 🙂

Ooops. I posted in the wrong thread. Sorry.

A couple Contax Sonnars. Older images I have posted elsewhere (pardon please)

A few more from the Contax G 90 2.8. Wonderful lens.

This time the 50mm f2 Nikkor-hc in ltm (Sonnar design)

The "Sonnar" name has become more so a marketing and trade name for Zeiss rather than an optical formula as it once was.
The Contax f2.8/85 and G Series f2.8/90mm lenses were both Ernostar schemes )maybe the f3.5/100 as well).
Eventhe ZM f2/85mm was a double Gauss yet paid homage to the classic f2/85mm sonnar from the Contax RF system.

There may be some other examples as well.
Vario sonnar has been used since the Contarex days if I remember correctly. That name as well has little to do with the traditional Sonnar Formula.

Cheers!

This lens broke my habit of using Tri-X when shooting 35mm.
