Hooked on photography since almost 60 years, I try to not being a fanboy of any system, this makes me free to use the best or the most convenient camera for any kind of work. Thats why I will continue to take photos with CaNikoMinoltaMamiyaOlySamsungFujiflex through any piece of glass from alpha to zuiko ;-)

LMCasey: I don't understand the rationale for this lens. A fast ultrawide zoom for APS-C. Like other posters have said, why not a prime, and why not even faster so that you can isolate the background. Unless you are very close to your subject, the fast aperture still won't give a satisfying background blur at f2. DOF is still surprisingly deep at large apertures with AOV this wide.

Well I would really like 12 and 16mm F2.0 APS-C prime lenses with AF and super abberation control - but I fear it's not gonna happen with Canikon in this century.
In this context, the Tokina suddenly makes sense for available light, astro and aurora photography. If the quality is there, I might exchange my MF Samyang 16mm F2.0 for it.

sebastian huvenaars: Turn your nikon into a Sony R1 :) kinda...

Yes, and with a choice of upgradeable sensors behind. This lens is on my wish list for at least 10 years...

aldoc: Great photograph and great b/w rendering and tonality. Is that a real scene or a composite of car and landscape with steam RR?

2mins later: Guess you gave the answer in the challenge thread...
Anyway (what I wonder really): on which RR line is that scene (Durango&Silverton RR??)
Alfred

Thanks a lot for your answer, it seems you were lucky enough to catch the last puffs of a working engine before it broke down...
There are a few historic steam trains +/- regularly operating in Switzerland. Many volunteers spend their spare time to keep them going. I understand, that at times the monetarian and human resources are just too scarce to keep the old RR going ... which is a shame as you said.

Joseph S Wisniewski: Makes a lot of sense to me. The thing I don't get is why Oly?

75mm is a bit of an odd duck on four thirds, 3.5x the "normal" focal length for four thirds (a 150mm equivalent). The classic portrait lenses are 85, 105, and 135mm, 2x, 2.5x, and 3x normal.

75mm is the portrait lens that everyone wants on APS-C, where it's 2.5x normal, but quite awkward on four thirds.

Does anyone know, if the image circle of this lens would cover APS-C? Might be we are in for a surprise after a Sigma-Oly specified waiting time???

KAllen: Whenever Leica release anything I think there is a rush to be amongst the first to complain about the price. Should Leica build like the Nikon, Canon Olympus etc? just be another volume over quality camera maker, justify the price with more pointless software gadgetry built in.
I'm glad the World can still find a place for Leica, I'm glad people still make enough money to buy them.
The Leica value will be in this lens in twenty years time, my Canon gear will be worthless by then if it lasts that long.
I've never owned a Leica but I'm glad people do. I hope it sells well and I hopeit performs brilliantly even if it's just a bench mark for the others to be judged against.
I'd have one.

PS Although I am not able to afford such a masterpiece of optics, I am just enjoying that such gems are made and would like to thank Leica for doing so.
The value or worth of an object is not dependent on possession, you can admire a movie although that marvellous and perfect star won't kiss you ever...

It is not the worlds first 180mm F2.8 Macro, but the first to go to 1:1 without additional tube. I have before me a review of 1996 Chasseur d'Image magazine about a "Sigma AF 180mm f/2.8 Apo Macro" with the then famous "Zen" finish ( ;-) ). Conventional AF and MF versions were made alongside at this time, no OS of course, 13 lenses in 11 groups including some ED elements. Minimal focus 0.64m, (0.5x). 85mmx180mm, weight 1580 g, Filter 82mm. It was made in a big variety of mounts: FD, EF, MD, MAF, NI-AF, NI-AIS, SA and K -- long, long time ago... BTW Price 8490 FF, maybe around $ 2000.- in todays world.

@GeoMaree et al.: No problem with the rapidshare link. Watch out to copy the entire link, it is very long and expands past the right margin of the text window!
