As is always a bit of fun, I’ve gone through and pitted these two cameras against each other to see if I could tell much in the way of a difference in the file quality. DXO says there’s a 4 point difference in the performance between these two sensors (in the GX7’s favor) yet they seemingly employ the same sensor and processor… Seems a little weird, and while I feel DXO does a good job at giving all of us a great resource from which to compare different cameras, it didn’t seem to add up on paper. C’mon in, We’ll have a look at files from each of these micro 4/3 cameras…
Okay, much like the “effective focal length” discussions, there seem to be many “effective aperture” discussions going around as many of these mirrorless interchangeable lens compact system cameras begin to really round out their lens offerings. Well, I guess the micro 4/3 system has while the Samsung NX is getting there and Sony NEX system users still have a small handful of options, but not really here nor there. The fact that so many lenses can be adapted across various formats can complicate the discussion. Along with those who shoot with APS-C DSLR cameras, all references for focal length and depth of field seem to fall back to a full frame/35mm sized sensor as the benchmark. There are some misconceptions as to how the aperture, or focal length affects the exposure or depth of field in these varying formats.
C’mon in, we’ll straighten this all out.
The Micro 4/3 system has really grown up in the last year. Sensor tech has taken a substantial step forward and the lens lineup has rounded itself out very nicely. Much has been eluded to regarding the origins of the OM-D E-M5 sensor, is it a reworked Panasonic sensor, a Sony sensor, an inhouse super secret sensor??? Oly came out and admitted that Sony is the manufacturer of the sensor in the OM-D E-M5 quelling the rumor mill, and of course, the G3/GX1 (and quite possibly the soon to be G5) sensor, built by Panasonic, is in fact different. That all said, I really wanted to see how these two sensors compared to one another as I have been very impressed by the G3. C’mon in and we’ll take a closer look at a few files.
Focal length? Effective focal length? Actual focal length? Crop factor? Do you get more reach with a crop sensor? Is it equal to a longer focal length? There are some misconceptions surrounding what happens when a lens is used on cameras with different sensor sizes. Let’s have a look at the differences between a full frame, APS-C and micro 4/3 sensor.
I like to spend time on flickr. It is an amazingly diverse community of photographers ranging from absolute novices to consummate professionals. One of the questions that come up in the gear groups there and in conversation with other photographers quite often is, “which lens should I purchase?” With interchangeable lens system cameras coming down in price by the day it seems, it is becoming much more accessible to acquire high quality photographic tools. One of the main benefits to an interchangeable lens camera, is just that, lenses! Which to choose and why? C’mon in and we shall discuss. Before the end of this article, you too will know which lenses will provide you with the best bang for you buck, depending on which buck you choose to bang… Continue reading
The start of a new decade brings with it a shift in digital image capturing technology. From an ambitious snapshooter’s perspective, perhaps the most versatile system has presented itself. While the discerning professional may not consider the micro 4/3 system cameras heavy lifting tools, it is at least an intriguing compact system for lighter shooting. Continue reading
