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!

I like it Curtis, reminds me of my hometown. I used to get in to watch a movie for a buck when I was a kid.

You know, we always kid newcomers about this place being addictive, especially when it comes to NMFAS aka Nikon Manual Focus Acquisition Syndrome. But, if you did a proper study, I think you'd discover that it really was!

No problem. I am just trying to rationalise to myself how these lenses create images like Rays first one. The practical implication is that the longer lenses make it possible to get the whole subject in focus, while the whole background is dreamy-blurred. If you shoot with the 50 f1.2, you can get plenty of background blur, but it is challenging to get the whole subject in focus wide open, i.e. the working DOF at a given magnification is reduced on shorter lenses (for an equivalent amount of background blur).

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!

I completely agree with you., and this brings me back to my thought process to use a longer lens for portraits, as you have both nice working distance as well as nice blown out bg.
So if I were to choose a shorter telephoto such as 85mm or the 105mm, I like to determine the distance between the subject and the background before choosing a focal length.

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.

You'll hear good things about the 28 f2.8AIS from me for sure. Just in case you had second thoughts :-)

Yes, I have shown the different working distances 1.5m vs 4m to give roughly the same subject size.
Of course there are plenty of other factors in lens choice! Another practical example is when doing a head shot with a 50 @ f1.2, you will be challenged to get both eyes in focus. With a 135 @ f2.8 (which will give similar degree of background blur) your headshot (at a greater working distance) will more easily get the whole face in focus. As well as the more flattering perspective of the longer lens, you also get better focus control on subject vs background. The other thing experience users will know, is to move subject further from the background where possible.

Don't worry about it Alan, we've ALL fallen victim to this! The 28 is a fantastic lens and really fun to use, especially close up.

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

I got a decent, though not mint off a "popular auction site" for £220 recently. They don't come up as often as the f2.8. Apparently there is an optical difference between the AI and AIS versions, so get the later one.

Ray Lovely photos. Neat how a long fast lens selects in 3D. The lily background is great.

James Markus was discussing the 500 f8 reflex the other day.

I've used this lens over the years starting with the Nikon AF400 camera then the D70 and also on the D200

The first two were handheld and the third from our deck at about 300' from a tripod.

The lens is very tricky and the slightest shake, mirror or otherwise can wreck the image. Nonetheless it is quite useful at high ISO and shutter speed.

What about the 28/3.5 pre-Ai?

Which model is this one, anyone knows?
