    Olympus 25mm f/2.8 reviews

    Zuiko Digital 25mm f/2.8 Lens is rated 4.4 out of 5 by 39.
    Rated 4 out of 5 by from Nice normal lens I'm using this lens on an Olympus EP1 with a Panasonic 4/3 to micro 4/3 adapter. The combination works well and the lens seems to function as required. Optical performance has been good. I've been happy with the photos I've done with this lens but I honestly haven't had a chance to use it a whole lot. Based on my observations so far, it's a solid four-star assessment. The lens seems very well built, more solid than the EP1 17mm and 14-42mm lenses. The combination of the lens and adapter are heavy compared to both the other Olympus lenses I have but this improves the balance of the camera. So far, I'm liking it.

    Rated 3 out of 5 by from Small Size Is The Key Feature The small size and light weight of this lens are the only reasons to consider buying this lens. Optically, it's not the excellent lens that previous reviews would lead you to believe. Quite the contrary. Chromatic aberration (CA) is the biggest problem you'll find. Not only will you see CA at the edges of the frame but even towards the edges of the inner third of the frame. Sharpness and contrast are characteristically so-so, typical for lenses in this price bracket. As others have already noted, the screw-on lens cap is really an unnecessary annoyance. But if you really need a pancake style lens for your Oly this is about the only choice.

    Rated 5 out of 5 by from Unusual and fantastic I use this lens on all my cameras, but mostly on my Evolt E-330. The combination looks like a very nonthreatening big P&S camera which is often useful. The lens is incredibly small and so can always go in your bag or pocket. It is a very good performer, way better than average as all the Zuiko's are, but it is standard grade, not high or super high. Of course that's reflected in the very reasonable price. The only downside is the true loser of the screw-in lens cap. Yes it makes the lens a couple of mm thinner. But is extremely difficult to use, especially if you have a UV or polarizing filter attached. Suggestion: get the cheapest snap in cap you can find or spend $6.96 on the Olympus LC-43 snap in cover (made for P&S cameras) and have the word Olympus on the cover. There's no lens hood. Olympus apparently plans to sell on for $39.95. I've found no need for lens hood on this lens in extensive testing. All in all, a great lens at a very useful focal length. And too cute and too neat.

    Rated 5 out of 5 by from Small and Portable It is exactly what I wanted in a lens. It's very small and unobtrusive, very easy to carry and takes very good images. The focal length is the old-school standard on a 4/3rds body, so it's amazing useful for everyday shooting. The only down side might be the hard-to-find filter size. Nobody in my area carries 43mm filters or clip-on caps, so you might want to order them whith the lens and save yourself some futile legwork. The supplied lenscap is an aluminium screw-on affair which is really cool for about a day, then it just becomes a pain in the field. But I didn't let this drop my rating because a lenscap is a pretty easy thing to replace (if you can find the 43mm size) and doesn't really have an effect on the lens performance or portability.

    Rated 5 out of 5 by from Great little lens! This lens has become my walk around lens, it is a perfect fit for my olympus e510 and I just love how sharp (for a $ lens) it is. I also love the fact that with this lens the e510 is so small, I can actually carry it around anywhere in my messenger bag.The bokeh wide open is quite nice, keeping in mind the four thirds sensor limitations. The macro capabilities are also pretty nice for such a small lens, being able to focus really close to the subject.The only thing I don't really like is the filter size, 43mm is not very common, but I guess I'll be using a step up ring so I can use my 49mm filters.

    Rated 5 out of 5 by from A perfect fit for the E420, E520 , E620 This lens just seems to be a natural fit for my Olympus E-520, incredibly thin and light, very non-obtrusive. Plus, I can use a much smaller case for my gear when I pack it; it fits in the top zippered compartment where I keep filters! I'm extremely happy with image quality and overall sharpness. I shoot predominately outdoors, but have done some ISO 400-800 stuff indoors without a flash and it works pretty nicely there as well, in fact I was surprised by the indoor images. For the price, the lens performs much better than I thought it would, and I find myself using it on more occasions than I had originally planned. The only downside is the goofy metal screw-on center cap that comes with it. You might want to order a couple of plastic snap-on lens covers instead, they are much easier to use.

    Rated 5 out of 5 by from Light and portable Complaining about the lens cap will be common to all reviews. It is a metal screw-on disc, that is hard to work unless the camera is facing up. Order a 43mm pinch lens caps when you order, along with a protective haze filter. Don't plan on a thick filter, such as a polarizing filter or a stack of filters, because you will cut off the corners of the image. Even though this is a standard quality Zuiko (expensive but not REALLY expensive) it has a metal (not plastic) connector linking it to the camera body. If you have lived your entire photographic life with a zoom lens, you may not like a prime. You do your framing by zooming your feet back and forth from the subject--or move the subject. Be careful at the rim of the Grand Canyon. This lens is thin and light. It won't zoom, of course, but if you have 8 or 10 megapixels, you can crop and still leave respectable resolution. It's great for when your evolt series Olympus DSLR has to serve tourist duty or for holidays with the family. Auto focusing in low light is accurate and, although this is not really a macro, my rose pictures are quite presentable as are those of people.

    Rated 5 out of 5 by from Outstanding Lens I've now had this lens for several months & love it. I use it on my E-410 and my E-1. It takes great pictures & is extremely versatile. I solved the lens cap problem by digging into my Olympus Pen FT collection and using the aluminum, slide-on, 43mm lens cap from the 38mm f1.8 lens. It works great, looks cool & lends a nostalgic quality from the camera that popularized the original pancake lens for Olympus!! But good luck finding one for yourself.
