Take a look at the "densewithgrass" sample. Move your mouse to and fro between "Show Imacon" and "Show Howtek". Notice the vertical displacement of the rock just right of centre? That's the cause of the CA. It will also contribute somewhat to softness. The Imacon needs servicing.
I don't know why people persist in generalizing based on tests like these.
Wow!!! Even superpro's, like Joe Cornish had servicing their scannersThe Imacon needs servicing.

Just posted a comparison in the Howtek 4500 thread. Take a look..

I also got a scan made by another provider (Ian Scovell) and there was very little difference. His scanner had been meticulously set up by Hassleblad (Joe's was serviced by Hassleblad in the previous year also).
If you can't generalise based on real world tests, what can you generalise on ;-)

p.a. I've since bought my own Howtek and am getting a lot sharper results than those in the test.

the url should be http://www.timparkin.co.uk/blog/scannercomparison I had the blog moved into my website and didn't get all the 301's in place..
I should also add that I'm happy to send a transparency to anyone with an Imacon that thinks they can get a better result.. (if they can include a raw file too)..

I must have missed where film size is specified.
To get more out of a humble Epson scanner, you can switch from 4x5 to 5x7, a diagonal increase of 36%, and a 75% increase in film area.
Sometimes we forget that 4x5 is at the low end of Large Format.
It costs less to scan larger images with an affordable scanner, than scanning small images with an expensive scanner.
The Howtek will always get noticeably better shadow detail in dense images regardless of the resolution, and this may be important for some who shoot films like velvia with dense blacks. And if you want to shoot anything color besides Portra 160NC, 5X7 probably isn't going to be your best format for a reliable film supply.
Oops - I forgot about color film. You're right !
