Where to find camera software and advice on lens choice (EOS 5DSR)

SBT1 — Tue, 02 Jun 2026 21:36:28 GMT

Hi, I hope somebody more knowledgeable can help. I am buying a Camera Canon EOS 5 DS -R which is provided without the Canon software. Am I right to think that it is not a problem, as it can be downloaded from this website? Also, looking at the options that could be downloaded (Canon utility), only the model EOS 5 D is available as the closest to the Canon EOS 5 DS -R. I guessed that it is the same range and that should be ok, but I would like to be sure. Any advice would be great.

I also had 2 different pieces of advice regarding the lens I could adapt on it. I want to use for photographying painting and doing prints. My previous Canon camera had a Tamron lens: Tamron AF Aspherical XR DiII LD [IF] 18-200mm 1:3.5-6.3 Macro 62 A14, that I would reuse and adapt to my new camera above. Do you see any issue with this? Sorry it is a lot to ask but I feel slighly out of my depth:) until I learn more. Thank you in advance.

I hope some of this might be helpful.

I advise against adapting a lens for a different camera mount to an EF mount camera, but it would work for RF mount. The reason is distance from lens to sensor.

For software, https://app.ssw.imaging-saas.canon/app/en/dpp.html

Also free software gphoto2, image capture that comes with macOS, gimp, rawtherapee, darktable.

I have a couple of 5DS R bodies and I love the look of its output. Canon USA has the software download here:
https://www.usa.canon.com/support/p/eos-5ds-r

The 5DS R and 5DS were built from the 5D III architecture, the big difference between the 5DS and 5DS R is the R has no lowpass filter on the sensor in order to achieve the greatest resolution. In some cases, you will have to correct for this in post (aliasing results when a sensor is exposed to information with a bandwidth too great for its sampling rate) but when needed it is an easy correction to make.

I am not familiar with the lenses you have been using BUT if they worked with another Canon body of the same era they should work with your 5DS R. Realize that when Canon brought out these models, they had recommendations for lenses within their own lineup that had suitable image quality to bring out the best in the 5DS and 5DS R bodies. Other Canon lenses not on the list will work fine but Canon felt that they degraded the potential of the sensor.

If you shoot handheld, avoiding motion blur with a high resolution sensor requires a slightly faster shutter speed than typical. It isn't a huge difference but something of which you should be aware.

What camera model did you use with the Tamron? Judging from the range of focal lengths, the Tamron lens seems like it is probably designed for crop sensors. It would not be a good choice for a full frame sensor body.

It is a Canon EOS 350D. One person mentioned it would adapt because, with all DI Tamron lenses, it should work, but another person (all photo experts but sales person in a shop) mentioned it would be blurry on the sides of the picture.

If the mount on the lens is EF-S, then it will not fit on a full frame EF camera. If the mount on the lens is EF, then it will fit without an adapter but not illuminate the entire sensor because the lens is APS-C. There would be dark corners of the sensor not getting any light through the lens. Your image would be a circle. After cropping, it still might be better on the EOS 5DSR than on the 350D. A lens that you already have costs less than a lens that you would have to pay for.

A much better lens for that camera would be https://www.usa.canon.com/shop/p/refurbished-ef-70-300mm-f-4-5-6-is-ii-usm but it also costs more than a lens you already have.

@johnrmoyer @SBT1 3rd Party lens manufacturers DO NOT make EF-S lenses. Only Canon makes special APS-C lenses that cannot be mounted to FF/ 35mm Film cameras. All 3rd Party lens manufacturers use the FF EF Mount for both APS-C & FF. But an APS-C lens just projects an APS-C sized image circle instead of a FF one. @SBT1 I would NOT recommend using that lens on a FF camera. It’s not designed for FF nor is there a crop mode to make it work well. I would recommend looking into a lens designed for FF cameras.

Thank you so much for the information. I was wondering if there would be an adapter for this. If not, I may have to also invest in a new lens.

Thank you so much. It seems to confirm the second opinion I got. I will look into a new lens if an adapter can't address the issue.

I seem to be totally fixed on that camera. Thank you for all these tips. It seems I need to look into a new lens as well, but I will also look into an adapter if appropriate. I will also look further into the link you sent about the software.

Thank you so much. That seems to confirm all opinions collected so far.
