I've uploaded some more photos to my stream:

Flickr: - Hilmo -'s Photostream

 

In particular now you can find some portraits taken with the lens. In my view the rendering of the lens is gorgeous.

 

Thanks for posting the pictures. I like the OOF area in the portrait of the woman with the yellow and blue in the background.

The OOF area in several other poster's photos looked very nice also. Maybe, this will turn out to be one of the nicest lenses for this. I know that the OOF areas is the only complaint I have with my 35 FLE. Maybe this lens will be different.

 

This photo is also focused behind her eyes which is very encouraging because I was starting to think this lens had some sort of front focus problem, maybe not.

 

I also like the size of this lens. I could see how this lens could end up my camera a lot.

 

Encouraged and waiting...

Rick- I like your logic. And just think you have successfully convinced yourself to get and more importantly, possibly keep the APO.

 

Just think if you could ever get close enough to a mountain goat, you would have the finest quality image of a mountain goat on earth. One must be prepared on those high mountain treks you do while tracking mountain goats. Or maybe your R 280/4 could match this little 50 in IQ.

Yes. I have not yet done that, but once the APO 135 gets back from Leica NJ early next month I will find myself having to do the FW update. Until then I am fat, dumb and happy.

 

BTW, what does #41 mean anyway and for that matter #51 too?

 

The black and white codes form a six-bit binary code (0-63 in decimal). 41 is 101001 (2^5 + 2^3 + 2^0).

No, you won't. The camera will happily recognise a 6-bit-coded Apo-Telyt also with the older firmware (unless it's very old ... but that's unlikely). It's the Apo-Summicron-M 50 Asph that requires the latest firmware for proper recognition.

What is the problem?

 

A bit harsh if someone is unfamiliar with binary arithmetic and notation such as 2^3 and simply says that they don’t understand why 101001 is the same as 41. Nor did I until someone taught me many years ago.

 

101001 = 1x(2^5) + 0x(2^4) + 1x(2^3) + 0x(2^2) + 0x(2^1) + 1x(2^0)

101001 = 1x(2x2x2x2x2) + 0x(2x2x2x2) + 1x(2x2x2) + 0x(2x2) + 0x(2) + 1x(1)

101001 = (1x32) + (0x16) + (1x8) + (0x4) + (0x2) + (1x1)

101001 = 32 + 0 + 8 + 0 + 0 + 1

101001 = 41

 

The confusing bit is perhaps the (1x1) at the right. By convention any number raised to the power zero is 1.

Thanks ever so much. I guess I am kind of like the people who buy prints. They look at it, decide if it will fit on a wall somewhere, decide they want it, ask the price and buy if the price is right.

 

I look at the results of Leica product, decide if I like the results, decide if I want it, decide if I can use it, ask the price and buy it if the price is right.

 

I guess I should care more about how images are created in the "box", but I don't. If the "box" works for me, I go out and create images. This afternoon for my personal files, I took out my MM "box" and completed a series of shots with all my 50mm lenses from wide open to f8 including the MATE set at 50 and for fun my 21-35 R on a GF1 set to 25mm.

 

Never done this before (and probably won't do it again except maybe for 35mm lenses), but wanted to see what happened in the "box". Forgot my ND filters so some images perhaps over exposed at 1/4000, even though the DNG histogram looked fine and my 99% over was not flashing red at me.

 

All this "gear" talk is just an excuse not to go out in the cold. It might get down to 39 degrees F here tonight! Let's talk.

While this is a good idea basically, shooting half a dozen 50 mm lenses at one target like rounds from a magazine won't tell you very much ... except maybe a few coarse facts, like, is one of the lenses defective? In order to assess a lens' strengths, weaknesses, and characteristics, you'll have to actually use it for a couple of days or weeks and shoot many different subjects rather than just fire a few test shots. Then repeat with the next lens. It would take weeks or months to complete if more than two or three lenses are involved.

 

I also own several 50 mm M lenses, some of them for years ... and while I do have a basic idea how each of them performs, I'm still far from having explored all of their individual aspects and idiosyncrasies ... :o

Therefore don't bother if the code is 41 or something else.

The camera does something according to the code, that Leica engineers have programmed in the (newest!) firmware code.

We cannot influence that, we should take the pictures.

PS

I have the problem too, that I forget to look at the histogram at the right moment.

Perhaps it is easier if you include the column headings for base 2 (especially if the forum's editor would preserve the spaces so that all the entries in each column align:))

 

32 16 8 4 2 1

 

1 0 1 0 0 1 = (1x32) + (0x16) + (1x8) + (0x4) + (0x2) + (1x1)

1 0 1 0 0 1 = 32 + 0 + 8 + 0 + 0 + 1

1 0 1 0 0 1 = 41

I'm interested in knowing the opinions of the lucky ones who have this lens what they think of it versus the Noctilux. I have a 0.95 Noctilux, but it's such a beast that I really don't use it that much at all. I'm thinking I'd get more and better results with an APO (and save a bit of money, too).

I don't have one, but I do have the Noctilux. In my mind, the two really aren't comparable (other than the price, of course). The Noctilux is such a specialized lens, it's really hard to compare the two and I'm not planning to sell it to get the APO. On the other hand, with usable ISOs getting higher and higher, the need for something that fast is probably diminishing.
