Do you use lens caps?

    When I used DSLR, I never used lens caps, front or rear.

    On mirrorless, I use rear lens caps, but not front lens caps.

    I am more concerned about getting dust getting to the sensor with lens changes on mirrorless than I was with DSLR. Is this a legitimate line of thinking? Or is the risk of dust getting on the sensor the same as it was if a mirror were there? Is the shutter closed on a DSLR when not exposing?

    I would really like to not use rear lens caps in order to speed up lens changes, but I still worry about it. Anyone out there have any experience or opinions?

    I always use lens caps. They can get dinged otherwise. When shooting, I'll leave the front cap off, especially when I use a hood.

    I am not clear about how using or not using lens caps impacts dust getting on a sensor. Can you elaborate?

    If I throw lenses in my bag or pocket with no rear lens cap on, it gets more dust and junk on the rear element than if it has a lens cap on. Once I mount that lens, the dust and junk has the potential to get on the sensor. With mirrorless, the sensor has an electronic charge (that attracts dust) all of the time that the camera is on, which is much different than DSLR.

    I don't really care about the lens getting dirty or dinged, as that doesn't effect image quality, I just don't want to get my sensor dirty or damaged.

    I always shoot with the lens cap off. Photos tend to be underexposed otherwise. :rolleyes:

    I almost always use both, but I could go without a front cap if I'm on the street/job working quickly. Always a rear cap on my lenses though.

    Did you see the movie Sky Captain and the World of Tomorrow?

    Use both, unless time is of the essence and I'm switching lenses multiple times in quick-ish succession. Then the front cap comes off when I put the lens back in the bag.

    As your signature lists an E-M5, I would recommend taking steps to avoid exposure to things like dust as best as possible and to your level of comfort. While the E-M5 does have an automated cleaning system, Olympus does not recommend users try to clean their sensors manually because, IIRC, you can damage the IBIS system. Items that do not come off during regular automated cleaning, or by using some type of forced air, would probably need to be removed by a factory cleaning. Then again, YMMV, and only you can decide what works best for your style of shooting.

    Also, doesn't rear element dust/dirt show up more readily in the final image than stuff that lands on the front element?

    Good luck,

    You need to update the poll. I use front and rear caps and a UV filter. Not sure why you'd use a front cap and UV filter but not a rear cap.

    I am not lazy and I care for my gear.

    Rear caps: always. If a lens is not on the camera it has a rear cap

    Front caps: when a lens is off the camera it always has a front cap. When on the camera it's always capped when in the bag. When on a shoulder or wrist strap it is either capped or has a hood.

    I NEVER use the so-called UV "protection" filters.They often degrade image quality, never help the image, and are generally a waste of money.

  16. No rear caps? Ugh, no thanks. Olympus might make the best dust reduction system for ILCs but I've no desire to give it a harder time than is necessary. I do the same as some others have mentioned, being sometimes not recapping the front of a lens if it has a substantial hood, but otherwise the caps are always on (front and rear) when the lens is not on the camera.

    I always use both. I rarely need to change lenses that fast. I'm more likely to have lenses mounted on two bodies and just switch cameras. I use both caps to protect my lenses.

    If the rear element gets dirt or dust on it the image quality is completely screwed ... in my experience.
    So for me the rear lens cap is the most important for IQ, the front cap is for protection.
    It all has NOTHING to do with thinking about dust on the sensor, for me anyway.

    Look at the poll : no lens caps is an aberration for a good reason.
