Oh no! Take it back to the shop! Ask for an immediate refund!Anybody know for sure the affect two dust spots in this lens will have on pics?
I did as recommended. The lens is a Vivitar series 1, version 2, 70-210 f 3.5. This shot of the sky has +1.0 exposure.I think it's hard to tell. I believe in most shooting conditions you might not be able to see anything caused by it. However, it may show its effects on shots of blue sky and scenes where the background has a smooth light color with no objects that could potentially mask the effect caused by the speck. Just give it a try. If there's blue sky above, point the camera to it, increase exposure to +0.7 or +1.0, keep the aperture wide open and shoot.
well, as you can see the dust speck is showing up black, essentially this means (and it is on an inner element too) that it will be adding some effect to the transmission of light ... just as your lens iris does. It might reduce the T-Stop of your lens by as much as 1/20th of a stop. So when you've selected f2.8 you may be actually getting f2.81 or something a bit darker.Unless you're shooting blue sky at f/22 you'll probably never see a single bit of dust, even if your lens looks like an old kitchen cabinet.
lol I almost fell for that one!! When I was small I gel up my hair with that stuff and my mom still talks about it occasionally. She said it took her 2 hours to clean it off. Wait, are we talking cameras here?smear vaseline..
but it works! though I recommend using a filter to sacrifice ... as it happens I have a old Canon EF35-70 lens which seems to have come with this effect as part of its optical designlol I almost fell for that one!!
LOL ... yes, of course ... or the ones on ones rose coloured glasses (where are mine?)Wait, are we talking cameras here?
