Minimum Radius In Ho Scale

Test: A standard zoom for the PEN

from the Eifel you can see Sicily, Germany 2010

Today it should go about selecting a standard zoom for the PEN, a standard zoom lens that is, for an MFT camera. Choose from the following objectives:

  1. Panasonic Lumix G Vario 14-45mm f/3.5-5.6 ASPH OIS
  2. Panasonic Lumix G Vario 14-140mm 4.0-5.8 OIS HD
  3. M. Olympus Zuiko digital ED 14-42mm 3.5-5.6
  4. Olympus Zuiko Digital
  5. M. ED 14-150mm 4.0-5.6

There is still a newer version of the lens 1 from Panasonic, this is not available separately and in addition to a pen rather impractical, as its built-in image stabilizer is not directly on the lens- or can be turned off, but only over a menu item in Panasonic cameras.

are now perhaps ask some readers, why here, such a review appears of zoom lenses, as I had in my last post here announced my "liberation", which was that I sold all photo stuff out of my PL1 and 20mm/F1.7 Pancake. But of course it has an interesting discussion developed example in a forum , and suggests offered my colleague Mark in to write a guest article, and for all those of us who from time to time but have sometimes prefer a zoom, or even an urgent need, but because of the flexibility. And so Mark describes here now its completely subjective impressions and opinions about the above-listed candidates for a standard zoom on the Olympus PEN:

----------------------- -------------------------------------------------- ------------------------

"Let's face it: most would rather have a zoom on the camera as a fixed focal length, and We also do not like to change every few minutes, the lens. So it makes sense to have a standard zoom lens in its park, where you go out with just stay up and be sure to be ready for most subjects and situations. Unfortunately, Olympus or Panasonic not so far been a fast standard zoom (at least f 2.8 would be desirable!), Which would expand the Einsatzmöglichgkeiten even further. But probably such a lens would be again too big and too heavy, and would therefore not fit the concept of Micro Four Thirds. So I have looked at me the currently available lenses that Leo has already listed above in his introduction.

Let's start with No. 3, which is often sold as a kit lens with a PEN. It is wonderfully small and light, and can even be a clever mechanism to sink into itself, so it has to transport almost pancake character. But unfortunately beninahe, and the optical quality of this plastic-wee goes so close to the Panasonic Pancake 20mm/F1.7 as the highest mountain in the Netherlands at the Mount Everest! For starters, very nice but then eliminated No. 3 lens for me personally very quickly because of a lack of focus. Zoom also No. 2 I prefer not considered, although it has an excellent reputation. My reasons: Too expensive (about 700, - €) to large (8.4 cm long been run already) and above all too heavy (470 g). use the lens at the PEN I feel but then again my times with a large / heavy / expensive DSLR recalls. So actually, only the lenses No. 1 and No. 4 left, ie, the Panasonic 14-45mm and Olympus 14-150mm. Let's look first at the raw numbers:

  • Price: Pana 240, - € ... Oly 470, - €
  • Weight: g Pana 225 ... Oly 290 g
  • diameter x length: Pana 63 x 62.5 mm ... Oly 63.5 x 83 mm
  • Aperture: Pana F3.5-5.6 ... Oly F4-5.6
  • Closest focusing distance: 30 cm Pana ... Oly 50 cm
  • Filter diameter: 52 mm Pana ... Oly 58 mm
  • Viewfinder: Optical Pana, installed ... Oly no, only through the camera
The following are my personal impressions of the two lenses, and I hope they can help you, perhaps with a decision.

are terms of weight, the two lenses about the same, that's perfectly fine and is no problem, nice and light and extremely portable. Unfortunately this is not so for the size. The Olympus 14-150mm is much longer, and not only in the retracted state, but particularly in the case zoomed out. But already it looks very noticeable and intrusive, and seems a bit less stable than many other zooms, I know. Interesting comparison photos for your design is as here at dpreview . Speaking of zoom: On my copy of the Olympus 14-150mm zoom ring was set much too hard and thus turn not pleasant. Although, that, inadvertently, the zoom moves out when it is held down, but that is another way, as shown in the Panasonic 14-45mm. This can be zoomed buttery soft and still has no zoom creep.

What about the AF speed? Both lenses in this discipline is very good, better in any case for longer than the Panasonic Pancake 20mm/F1.7, and better than the Olympus 14-42mm. Both the 14-45mm and the 14-150mm are also very low and thus also in the films practically inaudible. I have not made any scientific tests, but seems to me in a direct comparison, the 14-45mm still focus a bit faster than the 14-150mm.

Now we come to sharpness and contrast, and this should be the main arguments for many buyers. Here the Panasonic 14-45mm for me just ahead, and that at all focal lengths. I say yet that the Olympus 14-150mm for its focal range is very good, and that most of it completely should be satisfied. But the 14-45mm is just a little better. Even though my test image was not created scientifically accurate, it gives the impression again that I had when taking pictures throughout the entire zoom range with the two lenses. If your trip with your mouse over the image, you can compare them directly. (100% crops)



image stabilizer is to say that the OIS is much better than the Panasonic in-body stabilization of the Olympus E-P1. Olympus here should quickly rectify in future models PEN! The OIS provides very reliable very sharp images down to 1 / 8, sometimes even up to 1 / 4 second (quiet Hands required), whereas I had with the stability of Olympus part in the same focal lengths even at 1 / 40 or 1 / 25 second was annoying a lot of waste. Basically I agree with Leo that a body stabilizer is better because he was then without exception it has every lens and mitkaufen not always from scratch, but he must then also be good enough.

For other properties, the lenses are pretty similar, especially as distortion and sharpness in the corners at wide angle are perfectly fine. The light moves so variable at a similar level, the initial light intensity is the Panasonic but at 3.5 (as opposed to 4.0 in Olympus), but the difference is at 45mm even then, there is the Olympus 14-150mm, only the light intensity 5.4, because the diaphragm to rise with him quite early.
remains So what remains as the bottom line? Who wants to have everything in one, that is, who would also have the telephoto zoom range is covered with, must have access to the Olympus 14-150mm. Who (like me personally) not so much in Telebreich photographed and would also have the better image sharpness that takes the Panasonic 14-45mm. So that we get then next to the much more effective image stabilizer, a stable, compact and lightweight lens at a much lower price. As a last little thing to mention, that using the Panasonic gets kindly supplied a bag and the hood, however, nothing in the Olympus, so you may need to buy even the Geli additionally!

the way, the photos were taken in this article with a combination of PEN E-P1 and Panasonic 14-45mm.
That was my (admittedly not very scientific) test of the standard zoom lens for MFT wichtigstens cameras. I hope it helps you in the buying decision! Thanks again to Leo for the publication of my guest article. "

It's always nice to have a second opinion. Even if it's not exactly what I think about this topic. Stay tuned for more interesting thoughts about photography and more pictures and stories. Thank you all for reading my blog. I'd love to hear from you in the comments!
