In my case the problem manifested itself as a strong yellow cast on dry foliage and grass...

 

Yep, exactly what I meant by above post regarding color effects from IR contamination, which most associate with the M8. Many think this relates to black synthetic fabrics turning purple, but it can occasionally be much more….grass and foliage a common example.

It corrects the undoubted IR sensitivity of the M (Typ 240)—less than the M8 and more than the M9. In the tropics I find [iR-blocking filters] a must. In north-western Europe less so.

Except under tungsten light. That's what I found, too—the M (Typ 240) is somewhat more sensitive to IR than the M9.

 

That said, the M9 also responds to strong IR radiation, albeit less so than the M (Typ 240) and much less than the M8. See attached a photo of my Loewepro photo bag, taken with the Leica M9 in the evening sun in May in Germany (geogr. latitude 49° N) with no filter. To the naked eye, the bag's outside appears just plain black.

Exactly Jaap, Jeff and 01af

The IR “contamination” also depends so much on the incident light strength. Here in the southern hemisphere, light is a little stronger, probably due to less air pollution, and the earth being a little closer to the sun (summer). Hence Jaaps observations regarding IR effects in the two hemispheres, from his (beaut) images from Africa vs Europe.

It is important when testing UV/IR filters vs no filters, that the images are shot in bright cloudless light. Flat cloudy days reduce the IR signature markedly…but still always apparent if you know what to look for (for the humble M8 anyway).

Cheers Dave S :)

Both the Nikon and Sony low-end P&S cameras use the Sony 20MPixel 1/2.3" format CCD rather than the BSI CMOS sensors used in the more expensive models. The Nikon S2800 is under $70, and the Sony is under $80. The latter has Optical Image Stabilization. I suspect that front-illuminated CMOS sensors do not have the fill-factor required for such small pixels and that BSI detectors are just more expensive than a similar-sized CCD. Just counter-intuitive to think of CCD's as being cheap alternatives to CMOS, but this is a case where BSI technology is required to compete with a CCD for image quality. This announcement from Sony will push BSI CMOS into the very-low end P&S cameras.

Cyber-shot Digital Camera W800 – DSC-W800 Review - Sony US

 

I did not realize that Sony still used CCD's in some of their P&S cameras. This one is 20MPixel and has liveview. They must be clocking the CCD really high to pull that off. But if anyone wants a CCD based P&S, will not cost much to get one of the last.

 

Hi lenshacker!

 

You almost talked me into spending 70 bucks.

But luckily there are four points against it:

 

- I happen to believe in film superiority, not CCD. One can change the "chip" after 36 frames.

 

- The lens in THIS Cyber Shot Camera sucks.

 

- The nightmare of another charger + set of batterIES, with the part missing in the field when you need it :(

 

- I'll never sell neither my M8u...

The trouble and costs I had to get the "u" update, though Solms is close by and folks there (and in Wetzlar now even more so) are extrememely friendly and cooperative.

...nor will I sell my very healthy M9-P :) knock on wood.

 

So, you see: the market is right again.

It ain't worth those 70 bucks, or it would sell out fast.

I think I'll pass that "bargain".

 

Cheers,

Simon

 

PS: This is smart-phone territory anyway - which will be increasingly the case.

And the market knows it.

 

 

Sorry, you were right many times before, which I truly respect.

Otherwise I would not bother to contradict you. Only this one time :)

Oh no! Michael, thank you so much for delivering this news to us.

 

Quick question for you: if Leica made a new M camera with an updated CCD sensor, do you think only 400 (or 1,000) would purchase it?

 

—Peter.

How can a CCD be improved? It is about maxed out already,

Wasn't the initial run of the MM1 500 cameras?

Not just the original MM, but also the MM (Typ 246). 500 copies is a typical size of a first batch – Leica would never consider introducing a camera when they thought they could sell just 500 or 1000 copies.

If Leica is prepared for reasons of prestige and marketing to make M60 basically M (typ 240) with rear LCD removed it would  for corroding CCD sensors, than classic would become legend

 

I am M9P & M user, my preference is M as a camera but love low ISO files produced by M9.

I share this, I always carry the M9 along the M - and photographs from my Monochrom are ultimate evidence of the beautiful rendering of the CCD
