"The I’m Back Film’s 20-megapixel Four-Thirds sensor can work alongside a wide-angle adapter to ensure the smaller-than-full-frame sensor covers a whole 35mm-format image area. Or users can take advantage of the crop factor enabled by a Micro Four Thirds sensor (2x crop factor compared to a full-frame image sensor).
As for why I’m Back Film uses a Micro Four Thirds sensor instead of a full-frame sensor, the team behind the product says it comes down to cost. A Four-Thirds sensor offers “excellent image quality at a more affordable cost compared to a full-frame sensor.” Further, as mentioned, when combined with a wide-angle lens filter, users can achieve the same field of view on their lens as they would have when using a 35mm camera sensor."
As someone with a bunch of 35mm equipment, this concept is appealing to me, but why not also offer a full-sized sensor at a higher cost for those who want one? This product will always cripple the camera so it's no longer WYSIWYG. The viewfinder will no longer represent what the photo will look like, even with the "wide-angle lens filter" attached. Yeah, when you add their magnifier (what it should have been called) the CCD sensor will "see" the same area that normal 35mm film would see without it, but the photographer will continue to see a larger viewfinder frame than the CCD will see. This makes it a non-starter for me.
Does anybody know of a similar product with a full-size 35mm sensor?
- wahnfrieden 3y agoNo way to overlay crop lines on a viewfinder?
- anonymousiam 3y agoNot without modifying the camera. The traditional 35mm camera has a mirror and prism so the viewfinder sees what the film will see. The crop lines would need to be added somewhere in the mirror/prism/viewer path. https://en.wikipedia.org/wiki/Single-lens_reflex_camera https://en.wikipedia.org/wiki/Single-lens_reflex_camera
- dylan604 3y agoYou could etch/overlay them onto the lens of the view finder itself. similar to the cross hairs on a telescope eyepiece
- NikkiA 3y agoGood film* cameras had interchangable viewfinder/focus-aids that are just an etched piece of glass in the viewfinder optical path. You'd ideally want to etch crop lines onto one of those. * And digital SLRs, most of the higher end Canon and Nikon dSLRs can take a replacement viewfinder glass that adds a manual focusing ring or suchlike, they're usually cheap about £30 last I checked (pre-covid), but fiddly to install.
- cultofmetatron 3y ago> this concept is appealing to me, but why not also offer a full-sized sensor at a higher cost for those who want one? I'm seriously baffled by the decision as well. full frame is a highly sought after feature in higher end cameras. I myself chose a z5 over the zfc because of full frame. That said, the new nikon Zf blows this out of the water if you want a high end sensor paired with the retro aesthetic.
- ncann 3y agoI like the Df better than the Zf. That aside, there's a certain satisfying feeling with using the film advance lever and the other mechanical sounds that it's hard to replicate with digital.
- roamerz 3y agoThe DF image quality rocks. I have one and my only nicks on it are the sub optimal focusing speed / accuracy especially in poor lighting and the max shutter speed of 1/4000. The latter not being a problem unless you like shooting wide open outside in daylight, which I do. I would consider the Zf if they release a silver version.
- sottol 3y agoThe only full-frame image sensor I'm aware of that you can buy in small quantities off Mouser and the likes are the CMV20000 CMV50000 (20 and 47.5 mpix) costing $2000-$4500 per sensor. Last I checked APS-C and especially M43 sensors were 1/4 to 1/10 the price. So imo it boils down to price. If I had $1M to burn, I'd love to make the same product in full-frame - with Leica-style microprisms so that it would work well with range-finders. Maybe now that film is getting really pricey, maybe there's more of a niche to use old cameras with digital sensors.
- Clamchop 3y agoYou can buy a FF sensor in quantities as small as 1 for less than that per unit, but it will inconveniently have the rest of the camera around it. /s
- dylan604 3y agoYou can buy full camera for the prices GP listed. Something seems off
- whaleofatw2022 3y agoI looked up the part numbers. The 47mp one apparently does 30fps at 7900x6000px, with a global shutter. it's more made for machines than photos.
- sottol 3y ago... when you buy in quantities of 1,000s is my point.
- et-al 3y agoSupposedly the company already made a full-frame version, but it's a lot clunkier than the newer m43 offering: https://imback.eu/home/35mm/ https://imback.eu/home/35mm/ https://www.photo.net/forums/topic/524587-digital-back-for-35mm-film-cameras/ https://www.photo.net/forums/topic/524587-digital-back-for-3...
