Leos Posted February 25, 2013 Share #1  Posted February 25, 2013 Advertisement (gone after registration) I have noticed a distinct yellow tone using my Summicron 8-element on the M9. This is compared to my other lenses (35 lux pre-asph, 35 lux asph and summicron 50). It is not too noticable on many subjects, but people skin will tend to look a little ill or something - it reminds me somehow of the disconcerting colors I got from cheap Sigma lenses on DSLRs a few years back  Is this normal behaviour for this lens ? I tried to look thru the lens to determine if anything went brown/yellow in there (radioactive glass perhaps?) - but it doesnt seem like it and looking on a white paper thru the lens, it looks well ... white Should I try to treat it to sunlight for a few days anyway ?

Advertisement Posted February 25, 2013 Posted February 25, 2013 Hi Leos, Take a look here Yellow color cast: Summicron-M 35mm 8-element (1st. version). I'm sure you'll find what you were looking for!
TomB_tx Posted February 25, 2013 Share #2 Â Posted February 25, 2013 Early Pentax Takumar lenses were known for yellowing. I've eliminated it by letting a UV lamp (black light) shine through the lens for a few days. This doesn't heat the lens like sunlight does. Link to post Share on other sites More sharing options...
