I've just picked up a Jupiter-9 85mm f2 M42 lens, serial number starts N73.... and wondered if my experiences with it are typical of the lens:
1. The lens has a slight yellow tinge to it. Should I add a coloured filter, adjust the colour post-process or ditch the lens?
2. Metering on GX20 using Manual mode and the Green Button is accurate from f2 to f5.6, but overexposure creeps in from f8 onwards, by f16 the metering is way off. The over exposure is more pronounced using matrix mode than when using spot or centre weighted modes. Apart from test shots and using the histogram, is there any way to ensure more accurate TTL metering?
(On second thoughts, is this a problem with this lens or manual metering problem with all lenses? - This is the only lens that I use manual metering with.)
3. Soft at f2 and f2,8, sharp from f4
4. Bokeh gorgeous - which makes me want to persevere with this lens, but the metering problem is putting me off using it.
Any comments?
