Optical resolution is the real figure; the interpolated one is arithmetic · review
Rollei PDF-S 240 SE, 1800 dpi to 2400 interpolated review
The only scanner here that separates its optical resolution from its interpolated one — 1800 dpi against 2400 — with a screen on the body and card slots for three formats.
The bottom line Eighteen hundred dpi optical — published separately from its 2400 dpi interpolation, alone on this shelf — with a screen on the body, automatic colour correction, and prints as well as film, for 103 €. It describes no dust removal, itemises no holders and publishes no bit depth.
On the listing
Five bullets. A multiscanner for photographs, slides, negatives and business cards, digitising and converting old images; a high resolution of 1800 dpi interpolable to 2400, said to let scan data be shown at far larger sizes than the small originals; automatic exposure settings or individual adjustment, with optimised brightness and contrast bringing out details invisible on the originals; no computer connection needed, with results checked on the built-in 2.4-inch TFT colour screen and saved to SD, SDHC or MMC cards; and USB transfer and power, connecting to a PC or Mac to move JPEG files across for storing, sharing and editing.
The only page on this shelf that separates the two. One number is what the lens and sensor see; the other is arithmetic between those pixels. Publishing both is the difference between a specification and a sales figure.
Four originals, including a business card
Two optical jobs in one machine: light through the film, light onto the paper. One other scanner here claims the same range.
A screen on the body, and no computer
Two point four inches of TFT, so a frame is checked where it is scanned. The card can be SD, SDHC or MMC.
Automatic colour, and nothing about dust
The third bullet corrects exposure and colour by itself. Not one bullet addresses the specks that land on every negative.
A hundred and three euros against fifty-two, at the same optical figure
What the money buys is the screen, the correction, the card formats and the ability to scan a print.
Availability
Between 103 € and 118 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.
The American and British Amazon stores carry it too, priced in local currency. Those amounts are deliberately absent from the range above, which reads euro stores only.

What it does well, and what it gives up
Strengths
Optical and interpolated resolutions published separately — alone on this shelf
Photographs, negatives, slides and business cards, all claimed
A 2.4-inch screen on the body, with automatic exposure and colour correction
Compromises
No dust removal, and no holders itemised
Eighteen hundred dpi optical, the same as the 52 € DIGITNOW here
No bit depth and no scan-speed figure
Specifications
Optical resolution
1800 dpi OPTICAL, interpolated up to 2400, in the second bullet — and the distinction is the honest thing on this page. Interpolation invents pixels between the ones the optics measured; it makes a bigger file and not a sharper one. Every scanner that publishes only a large number is hiding this difference, and this page publishes both
Formats accepted
Four kinds of original, in the first bullet: old photographs, negative film, slides AND business cards. Scanning a print is a different job from scanning a negative — reflective rather than transmissive — and this is one of two machines on this shelf that claims both
Holders supplied
Not itemised. The bullets describe what can be scanned and never list the trays or feeders that hold it, which for negative strips is the part that decides whether the frames sit flat
Bit depth
Not published
Dust removal method
None described. Automatic colour correction and exposure are named in the third bullet; dust is not addressed at all
Output formats
JPEG, to an SD, SDHC or MMC card, in the fourth bullet, or over USB to a PC or Mac for storing, sharing and editing. MMC support dates the design and costs nothing
Scan speed
Described as scanning in seconds, in the fourth bullet, without a figure. The 130 € Reflecta on this shelf publishes under two seconds a frame

What people ask before they commit
Why does the optical-versus-interpolated distinction matter so much?
Because only one of the two numbers is real detail. The optics resolve 1800 dpi; interpolation to 2400 calculates the pixels in between, producing a larger file with no more information in it. A page that prints only the interpolated figure is quoting arithmetic as if it were optics — and this is the one page on this shelf that separates them.
Can it really scan prints as well as film?
The first bullet claims photographs, negatives, slides and business cards. Those are two different optical arrangements — film is lit from behind, a print from the front — so a machine claiming both is doing both jobs adequately rather than either one perfectly. For a box that contains all of them, that is the trade.
How does it compare with the 52 € DIGITNOW?
On optical resolution, identically: 1800 dpi each. What 103 € against 52 € buys is the 2.4-inch screen on the body, the automatic colour correction, the MMC and SDHC card support, and the ability to scan prints and business cards as well as film.
OPTICAL RESOLUTION 1800 dpi, published · 35 mm and 135 negatives and slides ONLY · an adjustable quick slide feeder supplied, no other holder described · bit depth NOT published · NO dust removal of any kind · JPEG to an SD card up to 8 GB SDHC, card not included, or to a computer over USB 2.0 · scan speed NOT published · no computer required · a video output switchable NTSC or PAL, for a television · Windows XP, Vista, 7, 8 and Mac OS listed
Fifty-two euros for a standalone 1800 dpi scanner that writes JPEGs to its own SD card — and can show them on a television through an NTSC or PAL output.
Best for: A box of mounted 35 mm slides to be got through quickly and viewed on a television, where a print larger than A4 is not the goal.
RESOLUTION AS A SENSOR: 22 MP JPEG output, no dpi figure published · 135 — 35 mm — plus 110 AND 126 film, colour and black-and-white negatives and positive slides, all INCLUDED rather than optional · SLIDE FRAMES AND FILM ADAPTERS SUPPLIED, plus a CLEANING BRUSH · bit depth NOT published · dust removal by the SUPPLIED BRUSH — mechanical, not infrared · JPEG · scan speed NOT published · a 5-inch LCD TOUCHSCREEN with gallery view, usable as a digital picture frame · a quick-loading tray for continuous import · automatic cropping with manual correction · slides must be in standard 50 mm mounts
Twenty-two megapixels, a 5-inch touchscreen, three film formats included and a cleaning brush in the box — the most completely equipped scanner here at 195 €.
Best for: A household box holding several film formats at once, digitised by someone who wants the whole kit — adapters, brush and screen — in one purchase.
OPTICAL RESOLUTION 7200 dpi — four times the next figure on this shelf · 35 mm film and slides · holders not itemised · bit depth not published as a number, but SilverFast 9 is credited with a 16-BIT HISTOGRAM · DUST REMOVAL BY INFRARED: iSRD, the only true infrared channel on this shelf · output formats not listed; SilverFast 9 Ai Studio and Plustek QuickScan Plus supplied · scan speed described as 38 PER CENT FASTER than the previous model, with no absolute figure · REQUIRES A COMPUTER: Windows 7 to 11, Mac OS 10.13 to 12.x · an ADVANCED IT8 COLOUR TARGET on 3 slides, ISO 12641-2 compliant, valued at 99 dollars on the page · multi-exposure, HDRi and NegaFix named
Seven thousand two hundred dpi with a true infrared dust channel, SilverFast 9 Ai Studio and an ISO-compliant IT8 calibration target — the only scanner here built for archival work.
Best for: An archive of 35 mm negatives that has to be digitised once, properly, with colour that can be trusted and dust that does not have to be painted out.
