The odd/ worrisome thing though is that if you download the actual product flyer brochure for the lens - which looks like it is also a printed piece - Zeiss lists the same specifications as the website. So, this begs the question - will Zeiss no longer be listing accurate focal lengths for their lenses going forward in all marketing material? Will they also eventually do away with publishing MTF's (which is not listed in the product flyer for the lens by the way)? In fact, on the Zeiss lens page, I no longer even see how to get to the MTF's. Seems a slippery slope.

You're right, I downloaded some months ago several 'old' spec.sheets from Zeiss website and they have still accurate focal lengths -For instance, the ZF 25/2.8 is 25.7mm,. the ZF 28/2 is 28.5 mm. and the ZF 35/2 seems to be exactly 35mm,
The new files include now a DOF chart of doubtful utility but focal lengths are rounded to the nominal value

I've been impressed by the Leica for some time; it seems to be the perfect 28. An impressive piece of optical engineering. The ZF 25/2.8 comes remarkably close though (at least in terms of sharpness), esp. considering the price.

thanks John for the pictures and crops, they indeed look very similar. I appreciate your comparison very much. I've just let go of a Leica 28 at ebay, it went for 1060 , which was a bargain for the 28, but still a lot of money since I already own the 25. Makes me fell better about the 25 ;-) In you first post there is still missing the image of the 25 ?

snowboarder: that car shot is indeed very much leica looking. Couldn't produce that look with the Zf 25/2.8. Something strange going on in the trees at far left though, what is this? What pp did you do with that shot?

Guess, I can just as well post a few ZF25/2.8 shots

I'd like to see some shots at close range as the last one with the 28. Does anyone have a shot at that distance or MFD?

I saw that as well. The Leica 28 2.8 V2 I briefly owned showed a lot of cyan/blue LoCA wide open (I will see if I still have the samples) and I suspect that is what we are seeing here.
