Originally posted by Talisker I've had my DA*50-135 for over two years - it's been to the Antarctic and to Greenland, been rained on, seasprayed on, and hasn't missed a beat. If anything happened to it I would run out and buy another despite the infamous price increases having made it somewhat more expensive than the Sigma in the UK. I admit I have no firsthand experience of the Sigma, although I am the happy owner of three other Sigma EX lenses (see my signature) so don't have any obvious prejudice against them. It's just that the DA* 50-135 is so good...
What if what "happened" is SDM breaking? Would you really still trust the DA*s then? I know people sing praises of this lens, and the images from it certainly speak volumes of its optical quality, but I refuse to have a lens that only works for several months, then be in the repair shop for 3-5 months for something that's not my fault. I'm actually thinking I should pick up a cheap canon / nikon body so I can experience this lens without having to worry about SDM (pity the SMC though)
Despite this, I still really want a DA* 200mm... I really love that focal length, and hopefully SDM issue isn't as severe with less moving parts (no zoom)
