The thing about parallel cords was wrong the Wikipedia article about the words. I gather it's something about detail/microcontrast/overall feel, but can you define piqué a little more precisely?

My apologies, I should have used the English word right away! Kindly Vieux Loup Tamron AF SP 70-300mm f/4.0-5.6 Di VC USD for Canon 5D - miro - 01-21-2011 Back to the topic. Rainer I’ve pulled the trigger to buy Tamron 70-300 4.0..5,6 VC for my APS-c Cammeras. Positive point. 1. Good IQ - In development announce Tamron mention that will deliver class leading IQ. - MTF chart on Tamron site seems to be good. - Internet reviews confirm that too. - Local Dutch photo magazine confirms that too. - It seems that sigmas FLD and tamrons XLD glass redefines the lens IQ standards. Probably this glass is coming from Hoya. 2. Good Build quality – BQ looks better that canon 70-300 IS. - I like the tamron SP finish. - acceptable weight – for 400Euro I can get second hand Sigma/Tamron 70-200/2,8 for 400Euro but they are twice as heavy. 3. AF - it allows MF at any time. - AF ring works fine. Personally I find it even better that Canon 70-200 IS 4.0. It rotates more degree then canon 70-200 is and 70-300. - USD works just fine. I’ve compared this lens with canon 70-300 IS usm. Tamrom seems to be a little bit faster but it shakes around settling AF distance. 3. VC is OK. Limitations 1. No AF limiter – eg. 1,5m…Infinity and 3….Inf. Even that USD and MF works just fine 2. VC has only one mode. I don’t know how this lens will perform by panning. E.g. Birth in fly photography. Warnings! - The MTF charts show lower IQ at extreme corners by FF. Tamron AF SP 70-300mm f/4.0-5.6 Di VC USD for Canon 5D - miro - 01-21-2011 My tamron 70-300vc seems to be well centred and AF is spot on at all FL and up until 10meters distance. My lens is a little bit soft at center and corners wide open at 100mm but at 280mm seems to be a decent performer even at 5,6.'Since my living room is only 11 meters I had troubles to do target tests at 300mm. Tomorrow I'll do some outdoor shoots. Probably I'll keep this lens. |
