The 45mm TS-E is far too big for me to consider as an alternative to = any Leica 50. In any case it is, as mentioned before, difficult IME to = focus manually with any EOS camera. Yes I would agree that many Leica R lenses seem excessively heavy - 50% = or more heavier than many of their rivals' versions (but then they are = built to last and you can't have it both ways). There are exceptions - = the 80/1.4 springs to mind as a package that is a lot smaller and = lighter than the Canon 85/1.2 which is the only comparable EOS optic. = And if you cannot tell that the 85/1.8 and 100/2.0 are flimsily = constructed (relative not only to Leica standards but also to the = earlier Canon FD standards), that the focussing rings flex when held = firmly and have play even when new then fine - enjoy them and be happy = your experience is different to mine. On a related note I find there to be a worrying tendency for Solms to = produce ever heavier lenses: the APO modular series, the 180 Apo, 28mm = R and M, 50/1.4 R, 35mm M 1.4 and 2.0 ASPHs, the 80-200 R and more are = significantly heavier than the lenses they replace. To say nothing of = the R8 which seems to be a spectacular growth...I wonder if there is = some kind of marketing rationale behind this - to distinguish Leica's = perceived traditional construction from the Japanese high tech = plastics? NB Leica was paradoxically one of the first lens makers to = use polycarbonates in lens construction (e.g. the 50/2 R and the 35/2 = non-ASPH last version Summicron M). <Well where are the fast Leica lenses?> 35/1.4, 35/2.0, 50/1.4, 50/2.0, 80/1.4, 90/2.0 - all built to = professional standards of rigidity and durability to say nothing of the = image quality. Yes Canon has a number of super speed fixed focal length = lenses in the L series which because of the size, weight and optical = characteristics render them special use optics IMHO. In the 50mm range = I have owned or currently own 28-70L, 28-105, 28-135, 50/1.4, 50/1.8 = and the only one of these which I would regard as a fully professional = grade tool is the 28-70L - the others get out of alignment very easily = and only the latter is usable with my Lee filter system. Neither of = these last problems affects any Leica R lens in the 50mm range. I wrote =BEbetween super wide (say 17mm) and 100mm> and then you wrote = <Well, let's take 135mm> and <Or we'll go to super-wide. The Leica = 15/3.5(...)> If you sidestep the point I was making then sure you have = an answer... But to take yr points- the 14/2.8 is smaller and lighter and cheaper = than the Leica 15mm but the two examples of the 14 I have shot with are = quite fuzzy in the corners: I have asked Leica 15 users about this and = they say FWIW the corners are very sharp. My Nikon 15mm was much better = in this respect than the Canons for that matter. As for the 135 - it is = a good lens but IMHO is not built to the same standards of durability = and long-term fixability as the Leica 135: but for proof of this we = will have to talk again in 20 years! As a pro I would still choose the = Canon one though, if it was a lens I had much use for (which i don't). As for the Chasseurs report - for what they are worth (too simplistic = IMO) you are confusing light fall-off with fall off of sharpness: two = entirely different criteria. And what are they measuring in the = 'corner' - is it the corner 1mm or somewhere in the outer 3rd of the = image or what? My experience is the the outer 4-5mm of the image circle = within the frame is quite poor for the Canon EF 14mm, 20mm, 24TS-E, = 28mm (1.8 and 2.8) and the 17-35 at wider settings and very poor for = the 20-35 at the wider settings. IMHO this shows that Canon make lenses = to a different set of quality criteria to Leica: the wideangles are = consistently, apparently by design, uneven in image quality. The Leica = M and R wide angle series are not in general so ambitious in maximum = aperture or zoom-ery but are remarkably consistent in performance: for = me that is a preferable state of affairs but you are free to decide = what is right for you. Be glad you have a choice - one day your criteria may change. Rgds Adrian Adrian Bradshaw Photojournalist Shanghai, China
