Hola, voy as hacerme con una Ricoh gr iii y quiero hacer ampliaciones a 60x40. Serán fotos disparadas en blanco y negro.
Pensáis que a ese tamaño de impresión la calidad será buena? Es mi prioridad.
Perfectamente. La Fuji X70, que tiene 16mpx, a ISO 200 puede hacer excelentes impresiones de 24x36 pulgadas, o 61x91 cm.

Fuji X70 Print Quality Analysis
A superb 24 x 36 inch print at ISO 100/200; a good 16 x 20 inch print at ISO 1600 and a nice 5 x 7 at ISO 12,800.
ISO 100 and 200 prints look quite impressive at 24 x 36 inches, with excellent fine detail and great looking colors. This print has quite a lot of "pop" to it. Wall display prints are certainly fine at 30 x 40 inches, depending on your viewing distance, but for critical applications the 16-megapixel X70 performs best at 24 x 36 inches as a maximum print size. Note that the native ISO for the X70 is 200, with ISO 100 being an expanded setting.
ISO 400 also delivers a solid 24 x 36 inch print. While not quite as critically sharp as the print at the native and expanded settings above, and with just a subtle hint of noise in a few flatter areas of our test target, this size still easily passes our "good" grade for print quality. Of note, the 20 x 30 inch print here looks superb.
ISO 800 yields a 20 x 30 inch print that most definitely passes the test. As with the 24 x 36 inch print at ISO 400 there is the slightest trace of noise apparent in a few flatter areas like shadows, but not enough to suggest a reduction in print size. Fine detail is still quite good at this size as well.
ISO 1600 produces a solid 16 x 20 inch print, which is quite a large size for this sensitivity. Contrast detail is now beginning to fade in our tricky red-leaf swatch, and there's a subtle trace of noise in flatter areas of our target similar to the issues mentioned above, but still a good print for ISO 1600 with nice fine detail and good color reproduction.
ISO 3200 prints a 13 x 19 inch print that almost passes our good grade, and is certainly usable for less critical applications. The 11 x 14 inch print here is quite nice however, and warrants our full seal of approval. Contrast detail is now gone in our tricky red-leaf fabric swatch, but this is common among most all cameras by this ISO save for a few with larger sensors.
ISO 6400 delivers an 8 x 10 inch print similar to the 11 x 14 at ISO 3200, with good fine detail and full color reproduction. Other than the common issue with our red fabric swatch, there are really no other apparent issues and the print is quite nice for this gain setting.
ISO 12,800 allows for a good 5 x 7 inch print, which yet again is an impressive feat for this ISO sensitivity and sensor size. At this time, larger sizes are generally only found at this ISO on some full-frame and medium format cameras. There's nice color reproduction still being output, and very little in the way of noise or noise-reduction artifacts.
ISO 25,600 yields a 4 x 6 inch print similar to the 5 x 7 at ISO 12,800. While not a large print, there aren't that many APS-C sensored cameras that can deliver a worthwhile print at this ISO as of this writing, so a noteworthy achievement for the X70.
ISO 51,200 allows for a 4 x 6 inch print that's not too bad, and usable for less critical applications, but there's a bit too much noise to pass our good rating. As such, this setting is best avoided for printing purposes.
The Fuji X70 excels in the print quality department, no question about it. From a superb 24 x 36 inch print at native and expanded low all the way up to a good 4 x 6 inch print at the lofty ISO 25,600, your printer will thank you for images from the X70 even as ISO begins to rise. It's not a surprise that the highest ISO of 51,200 isn't capable of a good print, as not many cameras can yet pull that off without a full frame or larger sensor. However, knowing that you can count on good 8 x 10s all the way up to ISO 6400 from a camera as compact as the Fuji X70 is certainly reassuring while you're out in the field shooting.
