Lens characteristics (cont.)

Macro Focus

The X100 has impressive close-up capability - it can focus to just 10cm from the front of the lens, giving an image area of approximately 81mm x 54mm, equating to a maximum magnification of approximately 0.3x. This is one significant benefit over its most direct competitor, the Leica X1, which has a rather limiting 30cm closest focus distance.

As mentioned above, wide open sharpness in the macro range (and at minimum focus especially) is highly lacking, with the lens suffering badly from spherical aberration. Fujifilm warns about this in the manual, and advises against shooting with the lens wide open at such close subject distances; however for certain subjects this defect can be used creatively to add some atmosphere to the shot. Stopping down to F4 improves matters substantially, and the lens becomes critically sharp at F8.

Flare

The X100's flare characteristics are, like the camera itself, distinctly individual. With bright light sources inside the frame it's impressively resistant to overall contrast loss, but it does tend to produce an array of ghost images radiating outwards, which as usual become increasingly defined on stopping down. Where the lens can occasionally come unstuck, though, is with light impinging obliquely on the front element, which can result in image detail being degraded significantly. This kind of flare can be guarded against simply by using a hood.

The X100's flare characteristics tend to be most obvious (and, depending on your point of view, problematic) when shooting in low light or at night, which is when flare patterns and ghost images can become most visible against dark backgrounds. The X100 can also give quite extraordinary flare effects at F2, with psychedelic radial streaks emanating from point light sources covering an angle of about 150 degrees. This is quite unlike anything we've ever seen before - it certainly adds an unusual look to images.

Background blur ('Bokeh')

One of the advantages of the X100's APS-C sensor and fast F2 lens is the ability to blur the background to some degree (and rather more than with typical small-sensor compact cameras). The degree of background blur is mainly a function of the lens's angle of view and the diameter of its entrance pupil, and this means that the X100's 23mm F2 lens offers broadly similar capability to the Panasonic 20mm F1.7 for Micro Four Thirds, or a 35mm F2.8 lens on a full frame camera.

The X100 is capable of producing quite pleasingly blurred backgrounds, and in most situations the quality of the blur is attractive enough. Under certain situations backgrounds can get a little fragmented and 'busy', mainly with complex distant backgrounds at intermediate subject distances (around 2-3m) and with the lens wide open. Closer backgrounds are notably smoother and more pleasant, and on the whole there's not much to complain about here.

It took the industry 15 years to arrive at this digital camera. Looks like the awesome cameras from back in the days when camera builders gave a shajt. It is made in Japan, that alone will make me buy this unit. It looks like a real camera, not like the gazillions of plastic Chinese made bs that flooded the US market in the bast 25 years. Great job Fujifilm, this camera will put you on the top of the game (as long as you keep the Made in Japan stamp on it.)

looking at other prices cameras with no AA filter demand quite a significantly greater premium maybe by as much as 50 % over there standard counterpart example d800/d800e i think it deserves another full star at least , i dont think you understood the settings and buttons and functions of this camera i think if you did it would eliminate all your negative comments and now i can get this camera for below $700 AU
