  • Exactly, since when is the Atlantic coast known for low humidity? I think that goes west to Chicago :-) However, the white stuff the OPsees is natural on rubber. It's a sign that his lenses have at ...
  • If removing the rearlens is really just by removing the screws and not a retention ring it might be that there is some guey coating or paint holding it additionally. Had that on some lenses.
  • The writing on the lower part is German. Spiegelobjectiv Planachromatisch It seems to be a mirror lens. Not sure what the 40x/0.5 is. Might be magnification and aperture?! - When in doubt, C4 KJ6EPH
  • The Schneideritis can be repaired by opening it up and paint it over. Might give it another 10 years before it might come back but really depends on the glass. If the glass is OK and the price ...
  • Actually the Flektogon I have has an issue with haze on the last lens of the front element assembly. The lens was very dirty inclusive corrosion and paint peeling on the baffles of the funnel of ...
  • Wow, thanks for the input. If it is more for close focus would be perfect since my Flektogon isn't good for that due to some haze that seem to come out more when close focusing. I will have a look ...
  • Thanks Tom, no doubt they are a choice. The question is how much of a Flek is really in them and how come the 2mm difference. Was it "copy right thing" between socialist brothers :-) to come up ...
  • Created discussion thread MIR 1B 37/2.8 vs Flektogon 35/2.8
    I see in the past month more of these MIR 1B popping up at the bay and they are praised as Flektogon copies which might be but they are 37mm FL and not 35mm. Is that due to different "rounding" or ...
  • Yeah, in general I am but in the last three weeks I'm looking more for noise and noise  pattern that are coming out. I did a pixel mapping and maybe it's better now. Hope to upgrade to the newer ...
  • Looks good. I'm struggling at the moment with noise on the old 12MP chip in the EP3 or it's just imagination and hope to have a lot of light later on to get some shots together. Your pics make me ...
  • The corrosion ongoing in lithium-ion batteries is highest when the battery is either fully charged or fully discharged. So in general they the most suicidal battery out there since it neither ...
  • Created discussion thread Mamyia 80mm f2.8
    Finally got the 645 to M43 adapter delivered and had some remaining light when I came home yesterday to get two pics to check the lens. First one is with f8 to see how the sharpness is since I'm ...
  • Yeah, medium format adapters are very expensive and hard to come by. I have one in the mail and it takes longer from LA to SJC than it took to get from China into LA :-)
  • Additionally to leaving the auto mode off for face recognition and choosing manually the focus point you also chose the area for exposure and that should be the face you want to have in focus. ...
  • Went to the Sierra for a scouting tour for summer camping around Lumsden and Cherry Lake. The forest service has closed much of the back roads due to weather related damage so getting there was a ...
  • I'm pretty sure you will like it. Much more than the run-of-mill 75-200 which never were any good but bountiful.
  • I just wonder, how much does it cost to rent  an Oly camera for a day?
  • Replied in Battery swell
    I had this kind of swelling with a set of three aftermarket batteries for my EP3. They all have good capacity compared to the OEM that I still have but the swelling made them unusable for the cam ...
  • I like the B&W rendering, never tried it with red rocks. At what time of the day did you shoot there?  I would assume sunset till near darkness since the shadows are unusual and you get some stars ...
  • Are you at infinity or the hard stop of the lens? The bay picture has nearly nothing in focus and the rest, well...it's awkward. However, it does t seem to be a rotated element, maybe the lens is ...
