Review on Olympus M.Zuiko Digital ED 12-45mm F4.0 PRO Lens Black: Perfect for Micro Four Thirds Cameras by Srinivas Johnson

Bought mine at another store, regular Revain: 24-90mm f/4(T) is about as close to perfect as a compact zoom can get. Not only is the range perfect, the close-up focus is excellent too. With professional build quality and near-best optical performance in the entire range, this lens is a no-brainer at its small size, as it adds real value to your kit. Practical value means you appreciate it and forget its price. Other lenses you will have in your kit may wonder why we bought them and not for this lens. For the traveler or minimalist, all you have to do is choose the single or dual lens option if you want to upgrade to the 90mm equivalent. . The convenience of an all-in-one zoom like the 14-150mm or 14-140mm options is intoxicating. Then you have 12-100mm f/4 or 12-200mm f/3.5-6.3. It's a tough world. Price, weight, size, features, optical quality, oh my god! What I want to tell you about this lens is that the combination of all the great features and performance tends to outweigh the convenience of a single lens solution. Find a good 1:4 telephoto lens or pair it with a prime lens and you won't regret it. You'll find that this little 12-45mm f/4 lens is attached to your camera most of the time, and you'll be changing lenses a lot less than you thought. If you've bought and sold many other zoom lenses looking for the extra features this lens offers, you'll still come back to this. So save yourself time and nerves. It's a super fast focusing, super sharp, very well built and compact little gem. Works great with Panasonic or Olympus (I have a lot of them). I like it on my GX8, EM5 MKII and my G9 for landscapes and close-ups in nature. An absolutely fantastic lens. For those of you wondering if you should use a constant aperture lens of f/2.8, I won't endorse it. The fact is that on the m4/3 platform there isn't much of a difference in light collection or subject selection between f/2.8 and f/4. It is not worth. F/4 lenses are a valuable and practical solution for any mount. At a wide open aperture, this lens flips around. F/2.8 lenses generally need glare anyway. Stupid right? By taking advantage of modern sensors, you compensate for the f/2.8 aperture and get better optical performance. The argument for f/4 lenses is better than the argument for f/2.8 lenses these days. It wasn't like that before, but progress is impatient. Take it, no doubt. — Carl
