![]() This photo of a blossom was taken at f/4, an optimal aperture for sharpness, but the final image has very shallow depth of field. The solution? Shoot many images at an optimal aperture and stack them. This does get more of the subject in focus, but often it still isn’t enough, and you also incur significant loss of sharpness due to diffraction softening at very small apertures. When you want to get a lot of a macro subject in focus, often the solution is to stop down to very small apertures. This is exceptionally useful for macro shooting due to the extremely shallow depth of field that occurs when shooting macro. If you aren’t familiar with focus stacking, it’s a process of taking many images, focused at different points in an image, and combining the in-focus parts into a single image. This is a great feature for creating focus stacks where depth of field is limited. The Pen-F is the second camera to debut with focus bracketing (and the fourth to have it, after the E-M5 II and E-M1 had it added via firmware update). BANDING IN HELICON REMOTE FULLOf course, turning on silent mode with full electronic shutter will eliminate it completely. Electronic first curtain is enabled by turning on ‘anti-shock’ with a 0 second delay. It’s not too big of a problem, though, as the Pen-F includes a fully electronic shutter that also can be utilized as a first-curtain electronic shutter to help eliminate shutter shock. However, the downside of the recent Olympus stabilizers are also present, and that is a tendency for shutter shock at shutter speeds between 1/60 and 1/200s. BANDING IN HELICON REMOTE ISOUnder the Railroad – Olympus Pen-F with Panasonic 12-32mm f/3.5-5.6 22mm, f/5, 1/4 sec, ISO 200 The shot below, for instance, was taken at 1/4 second handheld and is very sharp. With wider angle lenses, I’ve even been able to get sharp shots as slow as 1/2 second. The Pen-F inherits 5 Axis IBIS similar to those on the OM-D line of cameras, and like you’d expect, it works very well. In my experience, the IBIS system is generally useful for allowing an extra four stops of handholding at slower shutter speeds. Of course, one of the best reasons to choose Olympus bodies for your MIcro 4/3 kit is the excellent in-body Image stabilization (IBIS). (Click to view full size) Image Stabilization In-Body Image Stabilization I’t something to use sparingly, but when used well, it’s a great feature to have.ġ00% crop of 80 MP HR shot above. This is a crop of the 80 megapixel RAW, which shows some softness due to diffraction, but there’s at least 50 megapixels of true data here. The full image above was captured using the HR mode, and as you can see in the 100% crop below, there’s really quite a lot of extra detail here that wouldn’t have been captured in a single shot. If you’re photographing moving water or skies with long exposures, this is less of an issue (as you can easily blur out any visible artifacts), but for sharpness in your image, you’ll need to shoot still scenes on a rock solid tripod. Objects that move will leave diagonal line artifacts in the final image. It works very well, but there are a few caveats.įirst, the camera must be completely still, so you are limited to tripod mounted shooting, and if it’s windy, I wouldn’t try it. ![]() Olympus manages expectations by outputting a 50 megapixel JPEG image, which captures essentially all the actual extra detail offered by this mode. The result? A true 80 megapixel RAW file with RGB color information at every one of the 80 megapixels. Because of diffraction effects, there’s not really a full 80 megapixels of detail here, but it’s still excellent. Blossom – Olympus Pen-F with Olympus 60mm f/2.8 Macro f/3.5, 80 MP High Res Mode It then completes the shifting to capture full color information at all of THOSE locations. ![]() It then follows by shifting the sensor up and to the side, placing the pixel array exactly halfway between pixels both horizontally and vertically. This alone increases detail since color interpolation isn’t required like it is for almost all digital cameras. This doesn’t add any direct resolution, but instead shifts the Bayer color filter array around such that red, green and blue values are captured for every pixel location, rather than requiring interpolation. First, the camera takes a shot, then shifts the sensor to the side one pixel, then down, then to the other side. It does this by taking 8 discrete photos and merging them into a single file. The HR mode takes advantage of the precise control afforded by the excellent in-body image stabilizing system to precisely shift the sensor to capture significantly more data than is generally available with the native 20 megapixel sensor. ![]() After the OM-D E-M5 Mark II, the Pen-F is the second Olympus camera to feature their sensor-shift High Resolution Mode (henceforth referred to in this article as HR mode). ![]()
