Most people talk about sharpness only... but I can believe that in terms of other optical qualities the 50-200 may be better. Bokeh for instance is quite ugly with the 40-150. It just happens to ...

I scanned all the slides taken by my (late) father. The results were mediocre at best, but then, the slides themselves can best be described using terms like "subject out of focus", "serious ...

I do not have the 50-200 but I do have the 40-150 and it is really good. I have several lenses so I can compare sharpness and while there are subtle differences between lenses they are all so ...

A ranger told us (in Shenandoah National Park): "when you encounter a bear you probably want to take a good picture... do not go closer to the bear, USE THE ZOOM" But for a bear in your driveway ...

https://www.dpreview.com/forums/post/61028176 This post shows what a 600mm telescope brings for smaller wildlife... Clearly with just 150mm (or 210mm) you may need to be too close for comfort ...

While this is a great lens, 150mm isn't really very long to photograph wildlife. You need to get at least the 1.4TC as well. Below is a picture taken at the "Hoge Veluwe", from the closest point ...

Have been there many times. One of my favourite NJ places. Lots of animals to see, like turtles, frogs, salamanders, snakes... But my last visit is from at least 10 years ago, so no m43 pictures to ...

I don't want PDAF because it has been reported repeatedly that the PDAF detectors on sensor cause noise patterns as these pixels receive less light and that is not 100% compensated for. I'd rather ...

Olympus introduced the E-M5 in 2012. (I bought one right away.) It was a major step up in image quality from all previous m43 cameras using the old 12MP sensor. At about the same time (just before ...

And that is 1.4142135... which multiplied by 200 rounds to 283.

Way way back I had an Olympus film camera and already liked that. Then digital came along and after a few compacts with not so great (but acceptable) results I got a Canon 300D (aps-c) which I ...

I have the 12-40 since the moment it came out, first on my E-M5 and later the E-M5 II. I got the E-M5 in 2012 with the 12-50 which was lacklustre so I was very happy when te 12-40 came out. I have ...

For landscape pics 12mm is often wide enough. An ultra-wide lens is mainly good for shots in tight places (narrow streets in old towns for instance). Not good for people shots where people are ...

or not... I never got this message so I'm not sure, but I have installed other software from "unknown developers". First, in settings -> Security&Privacy on the General tab you check to Allow apps ...

Can you tell me what's technically wrong about these panorama shots? I do realize many people may find them uninteresting but that's not the point. I have never noticed any stitching errors ...

When the E-M5 was announced and I saw the first pictures on review sites, taken with the 12-50 I was hopeful that this would be a good lens. It can be... My copy was mediocre at best. Not clearly ...

Whenever I used my cameras (not yet the E-M5 II) in freezing weather (meaning -20c to -25c) I kept it under my thick coat, so it could soak up some body heat. I only took it out of there to take a ...

Placed 64^th in the challenge. There was a whole modern art style theatre show near the river (in a dock) in Dublin in 2007. Not entirely clear what the story was (there were no words) but it let to some very nice image opportunities.

The lens is not really parfocal on any camera. It provides data that allows the camera to adjust the focus as you zoom to keep focus constant. This even works when you use MF and then zoom. (It ...

I want good image quality but not at any cost, mainly in terms of bulk. M43 gives you the possibility to go quite small and light while still having a "good" camera (I started with the E-M5 and ...
