rmcvey 0 #1 January 18, 2003 ive just purchased 0.5 and a 0.45 lens. The 0.5 suffers alot more flare than the 0.45. Can someone explain?? Quote Share this post Link to post Share on other sites
murrays 0 #2 January 18, 2003 Controlling flare gets into designing lens elements, multicoating of lens surfaces, number of air/glass surfaces in the lens, type of glass in the elements (low dispersion glass) etc. Is the front of the .45 somewhat shielded compared to the .5...like a built-in lens hood? Are you sure they have been compared in identical lighting circumstances? Are they from the same manufacturer? Are they sort of in the same price range? It could be due to any number of reasons....-- Murray "No tyranny is so irksome as petty tyranny: the officious demands of policemen, government clerks, and electromechanical gadgets." - Edward Abbey Quote Share this post Link to post Share on other sites
rmcvey 0 #3 January 19, 2003 thanks. i was thinking it might have been to do with the different focal length. The one with flare was cheaper than the one without. Quote Share this post Link to post Share on other sites
Quincy 0 #4 January 24, 2003 i was thinking it might have been to do with the different focal length. In a simple definition, flare is caused by the sun shining directly into the lens. The number of lens elements, multicoatings, quality, etc. can have an impact as well, but, buttom line, if the sun is in direct line of the lens, you can get flare. The 'flare' you see in a picture is a reflection of the iris on the various lens elements. Hope this helps. Quincy Quote Share this post Link to post Share on other sites
