Summary: Know it all Camera Gurus often refer to kit lenses as "crap". This lens proves them completely wrong. My new Panasonic GH4 micro four thirds camera didn't come with a kit lens so I started "researching" - reading online reveiws looking for a good budget lens solution. I needed a good all around lens and it had to be a native "MFT" lens so it would work with my camera's electronics and spare me the cost of getting an adapter.
Summary: I have an EPL1, EPL2, EP3 and EP5. I have owned the 14-42 original, II and IIR and this by far has the best resolution. It truly is the best kit lens you can get for the money. Microcontrast and sharpness is noticeable compared with the other lenses. The fact that it came with a lens hood is another big plus. I ordered mine used, from C & K Inc. directly from Japan.
Summary: I really like this lens. It is head and shoulders better than the 14-42 kit lens that came with my camera. The 14-45 lens operates smoothly, has metal mount, and a "quality feel" to it, and is much sharper - especially in the corners than the kit lens. This older 14-45 lens is far and away better in all respects. Panasonic has recently come up with a much better 14-42 kit lens, and I understand it is considerabley better than my original. I hope so.
Summary: Small and compact lens. I purchased this lens because it had stabilization and I found out it was an essential feature to have after my last photo trip. I can still put the camera with lens in my pocket and not have to carry a camera bag.
Summary: Did not get enough observable improvement over the supposedly less well regarded 14-42..... Tests were run at several f stops, several zoom settings, and ISO from 200-3200, then viewed on a Samsung 40" 120hz TV.....Actually, neither one was the overall equal to a Sony NEX 18-55 tested at the same time at same settings....... AWB was off outdoors, again compared to the Sony, but I think this was the G5 body at fault.
Summary: This is the lens that came with the Panasonic Lumix G1. I sold the outfit about a year ago. While I really don't regret selling the G1 (I discovered I do not like EVFs), I really miss that 14-45mm. It was/is a superb lens in every way. I was reminded of this recently when I printed some photos on 13x19 hot press inkjet water color paper. As well as being about as sharp as you could ever wish for, the lens rendition of color, tone and detail was astounding.
