What about the 28/3.5 pre-Ai?

Which model is this one, anyone knows?


Photosynthesis (http://photosynthesis.co.nz/nikon/specs.html#28) says it's the 28 3.5 H

Looks like it:

Although most of you will be bored , anyway I am posting my results of measured magnifications reached by my wide angles reversed on a D600. It could be useful for one or two of you. DX magnifications were result of a simple 1.5x multiplication.



Reversed old Nikkors lenses magnifications por labecoaves, no Flickr

A simple chart with my own measurements of magnifications for some old Nikkors reversed on a D600 (full frame - FX). I used a ruler with a 0.05mm scale as the subject as an easy way to calculate the magnifications
The working distance is from the focused subject to the BR3 ring used as a pseudo-hood.



A little lens porn too
Some of the lenses above when mounted on the D600 for the measurement shots:

UD 20mm f/3.5; 20mm f/2.8 ai-s; NC 28mm f/2; 28mm f/2 ai-s; NC 35mm f/1.4; PC 35mm f/2.8.

All shots handheld, natural light from the window; D7100 + Nikkor 85mm f/1.8 K ai'd & CPU'd at f/2.8.
The reversal ring used for all lenses was the BR2a, except for the UD 20/3.5: I used a generic metal ring (72mm). In the back of the lenses there is the BR3 ring which I use as a pseudo-hood and as a protection for the rear lens element.



And the "poor man macro zoom":

Reversed Nikkor 28-50mm f/3.5 ai-s, set at 50mm and infinity focus position.
D7100 + Nikkor 50mm f/1.2 ai-s hand held, ISO 320, f/2 top, f/2.8 bottom.



Need to find time now for some "real life" test shots.

Peter I like the round tones of these photos, the workers especially look very nice.
Looks like a out of focus bottle of Tabasco by the blue building!

Alan I think the latest model 28mm f/2.8 is the one to get.

D800 135mm f/2.8

Not bored at all, this is a great little resource. Every kit should have a reversing ring, if only because they cost nearly nothing. Would be nice to see some real world results!

Here's a couple using the 135mm 2.0 AIS

Ray - very nice examples.
What I like about these fast long lenses - which makes them very tempting - is their ability to give a more useful working DOF while still blurring out the background. I have just done a quick comparison with my 50mm f1.2.
According to one online DOF calculator:

50mm @f1.2 @1.5m gives a working DOF of 6cm
135mm @f2 @4m (to give equivalent magnification) gives a working DOF of 10cm
But at the same time you get around 60% more background blur (assuming background at infinity)

The calculations for the 200 f2 are even more dramatic, but the downside for these fast telephotos is the increasing weight. One of my reasons for switching to MF was to get a nice carry-around kit!


Interesting bit of info James, thanks for sharing.



New info to me ... very interesting, will have to check this out. Does the 50 and 135 at the scenario listed provide equivalent subject size in the frame? I've always thought of a 135 f2 as the "practical" limit for fast telephoto in terms of my willingness to carry around. I've always just assumed that the difference was in background inclusion that helped me determine which focal length to use.

Great to see you Ray! The 135 F2 is my heaviest lens weighing 860 grams. That's 60 more than the 180mm 2.8 ED. But considerably less than the 2550 grams that the 200mm 2.0 weighs. Of course the bokeh is determined by how far the background is from the subject. If you have room the 135 is wonderful but to me the 85mm 1.4 is the bokeh king.

Ray, the last one is VERY nice!

Thank you Leighton. I have so enjoyed my 135 F2 It is definitely another "tropical island lens" I hope you don't mind but I moved us from the desert island for some better BOKEH!!!!!

PS can't wait until you get yours

Great info, thanks for sharing. I noticed in your post and profile that you have CPU'd some of your lenses. Can you share which chip you used? I have several of mine chipped with the Dandelion chip, but was wondering what others were doing.

Thanks.

I think I've fallen victim to this....I'm going to justify finding a 28mm 2.8 AIS for the need of a wider angle lens and I've only heard good things about this one!


And don't even think about the 28 mm f2 AIS… similar close focus capability, but a whole stop faster


....and looking for the F2 version now.....


Not trying to influence you Alan or anything, but here are a couple from the 28mm f2 AIS. A close focus demo. I seem to have a thing of shooting wide angle pictures of things coming straight at you.

The American public would probably object if they started selling durians on the street too… (if you never smelt a durian, this comment will probably not make sense)

Had to google that one, looks interesting.

I LOVE the asparagus shot, well done! You're not making things easy for poor old Alan. We warned him.

This thread is SO fantastic. I open my computer to find endless talk about lenses from knowledgeable folks examining capabilities of different versions. Love your discussion of depth of field for different focal lengths James. And who but Jose or John would do such a detailed analysis and put it on a spread sheet. I love it.

We've all been good students and there is an incredible amount of information available from any number of folks on this thread. No doubt we prime the pump with the information we offer to newcomers. How could they not get excited about these beautiful lenses? Look at Jose's close up photos of some lenses from his collection... absolutely beautiful. I thought I was fixated on EX+ lenses and look at Jose. I guess one of the nice things about a reversing ring is that it doesn't matter whether a pre-AI lens has been converted...

Honestly folks, just buy them all... I'm never disappointed when I mount one of these lenses on my camera. They are a joy to look at, a joy to hold and pure pleasure to use.

Love that asparagus shot! A very convincing argument for the 28 f2!

Thanks George, and Curtis for the kind comment.

George, I have used this excellent resource for CPU'd my lenses:
http://pindelski.org/Photography/2012/03/08/adding-a-cpu-to-mf-nikkor-lenses-part-i/
and
http://pindelski.org/Photography/2012/03/17/adding-a-cpu-to-mf-nikkor-lenses-part-ii/

the CPUs I have bought are from the same seller (tagotech) at ebay suggested by Pindelski:
http://www.ebay.com/itm/EURO-AF-Confirm-Metering-Emulator-Chip-for-Nikon-DSLR-D90-D80-on-Lens-AIS-Leica/261293039786?_trksid=p2046732.m2060&_trkparms=aid%3D111000%26algo%3DREC.CURRENT%26ao%3D1%26asc%3D27%26meid%3D6757983143166007065%26pid%3D100040%26prg%3D1011%26rk%3D1%26rkt%3D4%26sd%3D261293039786%26

Just buy them all? It's come to this then eh? Lol

We walked past that fruit store and then we heard a loud and gurgled squawk. The bamboo cages alluded to what lay behind. Now *that* the department of health may balk at. Cats are so clean!

Chin I like the forms and the lighting in gato. That fruit must smell pretty bad for me to recognize it in the upper right of sleeping woman, though I've never smelled it!

James Nice 28 f/2 shots. I find it very easy for me to miss focus at f/2 and middle distances.

I should say, among the 28mm f/2.8 set, the last version that focuses closer is better.

D800 85mm f/1.4

Trying to catch up with the thread. Its raining here in NJ and did not get a chance to go out and take some pictures..

I mounted the 24mm 2.8 AI this morning (again the lens is soooo small, smallest I have owned).
I am setting up a balcony garden and these are the first signs.

Also I found that this is the easiest lens to manual focus. The Focal length helps i guess.

That looks like either the H or HC (multicoated). I have this lens and I think it is the only lens I have that doesn't have color fringing in the worst light. Look in my profile and click to my Flickr link. I have all my albums set to a specific lens. I have the HC...
