Fujifilm Finepix HS20 EXR Review
The Fuji Finepix HS20 EXR is an SLR-styled ultra-zoom with one of the most versatile zoom ranges. Its 30X optical zoom lens has an amazing 24-720mm equivalent range, starting ultra-wide and reaching beyond most super-telephoto lenses. The lens is mechanically-linked for smooth, quick and precise control. Like most ultra-zooms of a similar form-factor, the HS20 EXR has a complete of manual controls.
Like its predecessor, this digital camera is based on a BSI-CMOS sensor that has been upgraded to 16 megapixels and enhanced with Fuji's unique EXR technology. This lets it keep high-speed features while allowing triple-mode operation to capture high-resolution, high dynamic-range or low noise images.
Externally, the HS20 EXR looks exactly like the HS10. Internally, it uses the same sensor as the much smaller F550 EXR. Being the new Fuji flagship, the HS20 is very feature rich and includes all the features of the F550 EXR except for the built-in GPS. Compared to the HS10, a few high-speed features where slightly downgraded, most likely to keep up with a sensor that outputs 60% more pixels. Most notably the top speed at full-resolution is now 8 FPS instead of 10 FPS and the top video recording speed if 320 FPS down from 1000 FPS.

Suitability - What is it good for?
The Fuji Finepix HS20 EXR is defined by its unique lens. The huge range with built-in stabilization allows it to cover a range of photographic subjects like no other. Ultra-wide is perfect for architecture, landscapes, indoor shots and monuments. At the other extreme, a reach of 720mm makes it suitable for wildlife and even birding. To reach a similar range on a DSLR would require the use of a lens weighing several kilos and costing thousands of dollars. Needless to say, all other photo applications are covered: portraits, street photography, sports and more.
The mechanical-link allows smooth and quick framing of subjects. Notice that we did not say precise because the HS20 EXR suffers from a slightly cropped view-finder, so framing is not so exact. Having no zoom motor not only saves energy, it also produces completely silent zooming while filming video.
The Fuji Finepix HS20 EXR digital camera is designed for efficient access to its manual controls and offers a large number of buttons to directly control the camera without using the menu. This kind of efficiency that makes it usable in a hurry.
High-speed features such as 8 FPS drive mode and pre-capture makes it more usable that similar cameras for action. The low-light side of things is covered by its 100 to 3200 full-resolution ISO range which is suitable for most uses. At the extreme of low-light, the HS20 EXR stops being usable before its peers due to a slowest shutter-speed that is reduced by one stop for each ISO. At ISO 100, the HS20 EXR can take 30s exposures, at ISO 200 it gets reduced to 15s, by ISO 3200 the limit is a paltry 1s. We suspect this is the case because the noise-characteristics of the CMOS sensor would ruin images otherwise. While there is a Bulb mode, it offers exactly the same limit as manual exposure.
Pictures from the HS20 EXR can be printed nicely in sizes up to 20 "x15" thanks to 16 megapixels of resolution. Near the wide-angle end, the camera can focus as close as 1 cm using super-macro mode. The digital camera also allows control over the dynamic range it captures. Possible options go from 100% to 1600%, although these are not available at all modes and ISO settings. Increased dynamic-range may also reduce image quality in shadow areas.
Both storage and power use the most convenient and readily available formats: SDXC for memory and most types of AA batteries for power. The power meter can be tuned to a specific type of battery and the HS20 EXR can rejuvenate rechargeable batteries.

The Fuji Finepix HS20 EXR offers two methods of dynamic range expansion:
One method is called Highlight Correction and is available at all resolutions. The magic happens using the camera's processor to adjust the tone curve while actually exposing at a lower sensitivity. The consequence is that only a normal dynamic range is obtainable at ISO 100. One can boost the DR to 200% at ISO 200 and up to 400% DR can be captured at higher sensitivities. This gives two more stops of highlight headroom.
The other method, Dynamic-Range Priority (EXR-DR), is unique to EXR sensors and is available at half-resolution (8 MP). In this mode, the sensor uses pairs of adjacent pixels of the same color - which is possible by a special arrangements of the color-filer array - to form a single output pixel by reading one photosite partway during the exposure. This lets photosites be read before they saturate. This is clever trick needs a constant flow of light during exposure and therefore would not work with flash. With this approach the HS20 EXR can capture up to 1600% dynamic range, although we suspect it actually does Highlight Correction too to reach 1600%.
Color is controllable using Film Simulation and traditional Color (Saturation), Tone (Contrast) and Sharpness parameters. There are only 3 steps on each scale, so flexibility is limited. Film Simulation lets the photographer choose between five traditional film looks: Provia, Velvia, Astia, B&W and Sepia. The most natural results are obtained from Provia with Velvia and Astia giving over-saturated and under-saturated results, respectively. White-balance is very flexible. These is an automatic setting, 6 presets and a custom option. All these settings can be fine-tuned along 2 axis in 7 steps.
Best-frame-capture is a sophisticated mode to capture an ideal frame from continuous action. It starts working as soon as the shutter is pressed halfway, continuously capturing images of which only a few are stored, then adding more images after the shutter is fully pressed. The speed at which it does this is controllable between 3 and 8 FPS at 16 MP or up to 11 FPS @ 8 MP. The number of before and after frames is selectable, as long as the total is 8 images at 16 MP or 16 at 8 MP. So one can get 5 images before, 1 image during and 2 image after or 3 images before, 1 during and43 after, or any other combination which adds up to 8. There is a small but noticeable lag in this drive mode but it is clearly better than with most fixed-lens cameras. At least the display keeps up reasonably.
The 20 scene modes are divided into a set of 17 and a set of 2 and Sweep Panorama. Any of the 17 can be accessed by any of the to SP positions on the mode-dial. The next 2 are called Advanced Scene Modes: Pro Low-Light and Pro Focus. Pro Low-Light takes 4 images to combine them into one image with reduced noise. This is similar to what image software call stacking or multi-frame noise-reduction. Pro Focus combines two shots to simulate the background blur associated with fast lenses.
The Sweep Panorama mode is designed to capture a panorama continuously in any direction. The sweep angle can be set to 360°, 180° and 120°. The output is limited to 1080 pixels in landscape orientation and 1624 pixels wide in portrait mode, in the shortest dimension, giving at most an 11520 x 1624 panorama. Fuji greatly improved this mode since its early beginnings and the camera is capable of producing a panorama easily. The output can look impressive from a distance but is often full of stitching errors. Moving elements such as people and vehicles are very problematic. Close by objects also give it great difficulty.
Now, while Sweep Panorama has its issues, most people do not bother properly setting up their camera to manually stitch using a computer later. The trick is to have the patience for a lot of trails and errors. Movement must be done steadily and the camera kept level. If that sounds easy, it is not. At least the HS20 EXR stitches whatever it good up to the point where it could not go on. This means that the panorama may stop before the chosen angle-of-view has been swept. For some reason, it is also possible to do more and sweep around more than 360° which that camera happily stitches anyway. Just below is an example of over a Sweep Panorama spanning more than 360° with a rather good stitch. Note that ISO is always Auto in Sweep Panorama and in low-light it can go up to 3200.
