At least I had time to do a preliminary test on the new (for me) 36-72E macro capabilities:
The setup, from lower magnification (and larger working distance) to maximum reproduction ratio (2.94x) - but also ridiculously short working distance (< 5cm) - not good for scorpions/spiders for example
The "poor man" (USD 38.00 !) macro-zoom: 0.68-2.94x
Z7 + FTZ + BR2A reversing ring + K5&K4 rings (30mm spacing) + Nikon 3T close up lens + reversed Nikon 36-72mm f/3.5 + tripod and a focusing rail; ISO 400, f/11 at 1/20s; led lamp as source of light..

FYI - I was not in the area of Dayton where they had the mass shooting tonight. I was home in bed, have to work this morning sorting packages. Early reports are 7 dead so far.
Came to the thread hoping there would be a post from you. So sorry that your hometown has joined the many communities dealing with these tragedies. The death toll now stands at nine. I'm glad you're well Laura. Hope the same is true for you family and loved ones. Too many nutty people and too many guns is definitely a recipe for carnage.
Staying safe nowadays feels more like a crap shoot than anything else... shopping at Walmart? A day rambling around downtown? It is so sad.
At Jay's subliminal suggestion, here is the same night sky shot with my 28mm NC Auto. I also re-did the two 24s for exact evening comparison. Just the crops from the top of the photo are shown for those, as before. The crop on the 28 is a little larger due to the decreased FOV to approximate the same star field.
All exposures were the same: Nikon Df, ISO 3200, f2.8, 20 sec, hard infinity focus
Once again, the 24 f2.8 looks better than the 24 f2 - the stars are more like spaceship shaped, rather than butterfly (astigmatism). the 28 f2 is not as bad as the 24 f2. What is evident when you look at these, is one can see a definite circular boundary where things are falling apart - at least at the top. The bottom is all shadow. For example, from the 24 f2:
Apart from astro, I would never shoot these lenses at these apertures - rather more like f8 or f11. I think stopped down like that, these "problems" don't show up.
Thanks for looking.
Time to head out for some backpacking/fishing. for 4 nights. I have decided to leave the "beasts" (Sony A7RII and Df + lenses) behind and opt for my little Sony RX100 II. I have just read an article about someone who has done some impressive experiments with this little 1" sensor, and while it is new moon and no light pollution in the backcountry, I think I'll give it a try.
Thanks Lestor. It's definitely a crazy world and I was getting more info about what happened here, from British newspapers, than our own local news organizations, so knew I had better post something. Dayton's had quite the rough year with KKK, tornadoes, and this mass murder.

@Laura@ : Glad to know you are OK, Stay safe!
Condolences go out to the victims & souls lost to another mundane thoughtless act of violence following the Texas incident.
With the world getting crazier as days go by, sanity and tolerance is all we can sadly pray and hope for...
Quick tech question for you guys......I have a couple old manual focus zooms from 30-40 years ago, like Vivitars and Soligors and such, and was thinking of mounting them on my Z6 and see how bad they are now that focus is on sensor. In the CPU listing in the menus, what you set the lenses at for best results. Say its something like a 24-105 f 3.5-5.6 (example only) do you enter the data on the short open end, or long end for best results.
Doug Didn't you mean to say sublime?
Shooting starfields brings out the worst in lenses so you should not have to stop down to enjoy your lenses in most cases.
The man here was wearing full body armor but neglected to armor his head, which is where he was shot by the cops. In less than 30 seconds, even with the cops coming for him, he managed to kill 9 people and injure 26 more, using a magazine that held 100 rounds. A gun that can do that is not a hunting gun, it's a gun for killing people. You can't eat a deer pumped full of lead. I am thankful that none of my friends were killed or injured, but a friend of mine said her daughter was down there when it happened, in a bar across the street. Staff at the bar directed them out the back door of the bar.

I called the number on the sign and asked for “Sal.” They said there was no “Sal” there.

If you are not using in body stabilization it really does not matter which focal length you enter for the lens.
However if you are using in body stabilization you really need to enter the focal length you are shooting since the level of stabilization applied in camera is based on the focal length entered in the Non-CPU setting.
On my manual focus zooms I either turn off VR or specifically set the Non-CPU setting to the actual focal length or closest focal length being shot.
Macros with the pre AI Nikkor 55 3.5 P are the perfect excuse to revisit.
Compactness of the Contax G lenses on the z6 especially as a light travel kit along with the overall mf experience is getting to be quite enjoyable and addictive.
Hunting a decent Nikkor W 35 f/1.8 now but sadly prices appear just ridiculous here in the EU.

Interesting and helpful George. I plan on using Ibis, so it will be clumsy, but I just want to see how good or bad this glass actually is. I remember I had a Quantaray back when they were made of metal, a 70-210 or something like that, and it was a really good lens. Some of that old Vivitar stuff was pretty good as well. Any excuse to screw around, I suppose.

Yes, the price of Nikkor W in Nikon S (rangefinder) and in Leica screw mount have really increased the last few years. Especially the f/1.8. I found one early last year, but the condition was poor and the price was crazy high. Had to take a pass on that one. I am happy with the f/2.5 version for the time being

My sympathies to all the victims of the latest terror attacks.
In keeping with our ethos, I normally don't offer an opinion on politics, particularly US politics.
This time I have skin in the game - a son, daughter in law and 4 beautiful grandchildren living within 40 kms of Philadelphia.
God willing they will be safe!
I am pretty well versed on US history and understand the rights conferred by the 2nd amendment. What I cannot understand is the acceptance by congress of horrific annual casualties that are far greater than the 9/11 horror. In the aftermath the most draconian security legislation was introduced, two wars lasting more than 15 years costing thousands of lives were started which cannot be won but it's too much to ask to ban the sale of military weapons or introduce mandatory background checks - all to keep one lobby contributing to the politicians happy!.
This is not an invitation to an argument. However, from a distance it seems extraordinary.
I accidentally tripped and fell last week. When I woke up there was a Nikkor-Q Auto 135mm f/3.5 lens on my hand. My accidental fall cost little but I'm here to tell the story . I'm dipping my first foot in this club.
The lens is not converted and I don't know if I will find someone to do it locally but it works on my D5500, as lots of online research suggest these lenses should. It is in very good condition but came without body caps. The glass is impeccable. I'll make a plan for the caps although it would have been nice to have original ones for authenticity.
Short summary :- It's a whole new world but not as difficult to focus or get good exposure as I thought.
Here are two samples from this morning with D5500 at ISO 400 and F5.6.
Siphiwe, is this your first post here? Welcome! Watch out, some of the folks here have frequent "accidents" and wake up with lenses as a result Caps should be relatively easy to find for that classic 135.
