Hopefully the last of my lba spree:

Nice and compact Pentax-m 200mm f4 my Pentax-M primes collection now is 20-28(3.5)-40-50(1.7)-135-200

I am also amazed about how light it feels on the K-1

This is a great lens. My most extensive use was for a zoo visit. It is a great focal length for caged wildlife. My much larger 300mm lens, on APS-C was too long for anything except trunks and tails, but the much lighter and more user friendly 200mm gave nice closeups with great clarity. Hope you enjoy this lens as much as I have enjoyed mine.

do we use SMU's for new camera bodies?

You are the innovator for SMU design and deployment, so you are the final authority on this.

That said, Why not?

are you hungry ?

if so, go for it

The one I have is a "Vivitar Series One". Not sure its really from that series, but it's a 4/4 design, with a 67mm front filter.


I do imagine you are correct about example variance.

not sure what Vivitar Series 1 lens is being discussed here

this is a great site about the Series 1 70-210 zoom

Vivitar 70-210 Series 1 Macro Zoom Lenses - Mark Roberts Photography

Vivitar Series 1 70-210mm Macro Zoom
The cult classic lens
Page topics: Specs - Compatibility - Resolution - Serial #'s - Sample Photos

Introduction

In 1975 Vivitar introduced the "Series 1" line of lenses. They were intended to compete with the best offerings of the major camera manufacturers, albeit at a very high price -- they were quite expensive even by OEM standards. Nonetheless, discriminating photographers who could afford the price snapped them up and they are still much sought-after by photographers willing to give up auto focus in return for top quality optics, construction and versatility.

The most famous of the Series One lenses was the 70-210 macro zoom. One of the first zooms to offer any kind of macro capability, it offered outstanding optics in a highly versatile package. There were several versions produced over the years, the first three of which are still very desirable lenses. The last two manual focus versions are of poorer optical quality and are aren't really comparable to the earlier versions.

After the five versions shown here, Vivitar sold some really poor lenses under the "Series 1" label, which all but destroyed the prestige of the brand. Any of the autofocus "Series 1" lenses should be avoided, as should any of the ones that have maximum apertures of f/4.5-5.6.

Hi all,
My latest acquisition is an old Vivitar 400 F5.6 which is a bit gruby but in overall good condition when it comes to the glass. However the tripod mount is stuck solid and doesn't want to shift in any direction.Any ideas of how I could free it up, I've tried alcohol and oil so far but no joy?

I don't have the former; I quit smoking 25+ years ago, but I always have the latter. It is one of the three major RV carry alongs: WD-40, Duct Tape and Goop.

Found a Kodakgear 78-215 F4.5-5.6. Lens for Canon EF for £15 plus P&P today, checked it out and apparently it's really a Tamron and one with quite a good reputation. So I've ordered it, should find out if it's any good next week.

Posted a first tranche of infra-red photos from the Sony DSC-V3 on Flickr. They're OK, quality isn't much better than the DSC-VI but it's much easier to use due to the bigger screen, so I'll eventually sell the latter on.

Bodies are three dimensional. You need to simultaneously measure in each of the three dimensions, in case the body changes shape between measuring L, W, H.

A Raspberry Pi 3 B+, which I believe is the most powerful model to date. I'm looking forward to seeing what I can do with this (especially old skool games)

So lenses are not three dimensional?

this discussion doesn't seem like a rabbit-hole at all....
