Quite right. Although we grown ups may live thousands of miles apart, there is a groundmass of children who can transmit a cold virus from one end of the planet to the other inside 5 days.

I'm just getting over mine.

Yes, I'm proof. I've been battling with the same affliction over here since Monday, it's tenacious!

After two bouts of heavy colds/flu earlier this year and respiratory symptoms which affected me for over a month on each occasion, two weeks ago I consulted a charming lady pharmacist in Boots the Chemist who gave me a flu jab. No side effects and hopefully the three flu virus strains in the jab will provide immunity for the next 12 months.

My father used to give us a revolting "cold cure" drink made with blackcurrant jam, rose hip syrup, honey, hot water and whisky. It has left me with a life long loathing of blackcurrants  :p. Then he bought a part of a company making Thomson's Iodised Cod Liver Oil Cream, so we all had to have a dessert spoonful of this indescribably loathsome stuff every morning, to prevent us getting colds. Child cruelty I would call it. We finally persuaded him to let us go back to Radio Malt, which we all liked.

I am not sure if this has been posted somewhere: http://kristiandowling.com/blog/2015/11/6/the-leica-sl-type-601-review-performance-part-2

 

This is Kristian Dowling that some have commented that he is now representing the SL for Leica.  But, I have been following Kristian for years now and he is such a fantastic photographer and this is well worth looking at... if not just for Kristian's great photography.

Hm. That link isn't working for me. Just gives me a blank screen.

About the electronic/aperture connection to R lenses, I am not so optimistic, as Mr. Daniel, in his response to Andreas' question about the SL being the R solution, went something like: "Err...Ummm...in a spiritual sense maybe" or words to that effect.

 

I'm wondering about the R Adapter. It might have:

 

- electronic contacts, to tell the SL body what lens is attached and which profile to use

- a set aperture sensor, so the electronic contacts can transmit this to the SL for exif data

- an aperture actuation device that closes the aperture for the shot.

 

The first two points make sense and should be easy enough to implement. But what about the third point? Given that M lenses would be used stopped down, is there any issue with using R lenses that way? It would provide a constant picture preview. It would allow for higher frames per second.

 

What am I missing?  Thanks.

We have to look at the T-M adapter, which exists, and the functions that the SL executes with T lenses.  The T-M adapter has electrical contacts and IR sensors so that it can transmit the M 6-bit code to identify the M lens in use.  Will it transmit the identity of a ROM-equipped R lens to the SL?  That sounds well within the range of possibilities to me.  A 3-cam lens?  Dunno.

 

Then, we can ask if the SL with a T lens installed stops down the lens  well before the shot, at the half-press, or ...?  That's a question that can only be answered in a Leica store, I am afraid. If the SL doesn't even have the concept of Aperture stop-down, we are out of luck, but I suspect that it does know about these things.  Finally can the camera activate some mechanical action that the adapter makes on the R lens to cause the stop-down.  I believe even ROM-equipped lenses require that this is done mechanically.  That slows things down, and the SL may be reluctant to accept the requirement.
