Thread: 50mm f/1.8 double vision

  1. #1

    Default 50mm f/1.8 double vision

    Can someone tell me if this is normal ? It was about early morning and i jus took out the camera, put on the 50mm 1.8 and shoot my dinning room lights.

    Was very surprised that I saw 2 reflection in green on the pictures ?

    Can someone enlighten me why this happens ?

    All i have is the trusty Hoya UV lens protector filter. What lens filter should i get to counter this ?

    Its mostly likely a reflection off your filter.

    There's no filter to counter this afaik. Best solution is to remove ur filter for such direct light shots.

    Forgive me for being a little out of point, but your pics really look like a couple of those dodgy "UFO sighting" pictures. Strange effects - would be really creepy with some pp.

    On a more serious note, the 50mm 1.8 has pretty recessed glass, which may actually cause the reflection from the filter (because of long distance from between the glass and the filter). You could buy a really good quality pro-filter, but that would cost you almost 2/3 the price of the lens. No point. Would be better just to shoot without a filter; especially since the recessed glass means last chance of dust and grime getting in. And, if I guess correct, most of the shooting with this lens would be indoors anyway, hence not too much problem.

    Sure looks like UFO, given the greenish glow. Try shooting without the filter, should answer your query. Cheers.

    I should stop lying now. We are actually preparing to zap you guys (Re : Independence day) when some idiots was pointing his 50mm lens at us and we were worried that it was some earthing laser to counter our attack , we stopped and fly off.

    Until you give me your 18-200VR lens, I will take over your woman models !

    I just brought a 50mm with the same Hoya UV filter. Do you meant this kind of lens does not need a filter? 'Cus of the 'long distance' between them.
    So shd i put away the filter for good?
    Think i try it tonight and c how?
    BTW, not sure y i can't see the pictures posted???

    Yup... I always discourage using protective filters on this lens. Anyway, I have stop using protective filters for most of my lenses (dun have many to begin with... ) ... hate capturing those flares and the loss of contrast.

    Nope. Extra glass = extra chances of getting flare... even when using the best filters. (no matter how good the coating is... glass are always reflective... coating only reduces it.)

    Try with and without filter on scene with strong light sources... you will see some difference.
