Hi All
Seems like a great lens.
I am looking for a landscape raw file that has been shot on an R5 at about f11 70mm to do a cropping test. I have an EF 24-70 f4 with adaptor, and was looking at the 24-105 f4-7, but not happy with the corner quality. I also don't want to get the RF24-105 f4 as I take my gear on multi-day high altitude trips and am trying to reduce the weight.
The point of the cropping exercise is to crop the 70mm focal length image to a 105 equivalent focal length and see how the 45mp sensor handles it. I have for the last 14 years been using a 5dii, so think the quality should be good enough with such a crop, but would like to test this out befpre i spend the $$$.
If anyone can assist or direct me to raw sample files that would be great.
Thanks
Karl
I can't help you with a RAW file but the old EF 24-70 f4L IS USM will be a tough lens to beat. It was heavy and awkward on my R with adapter so I switched to the RF 24-105 4L IS USM. No gain in IQ but a lighter lens and more useful range (save for the missing .7x macro).

Interesting....I have the EF 24-70 f4L IS USM and I don't find it heavy and awkward with the adapter at all.... 😁
I am guessing that ignorance is bliss on my part, not having a RF lenses to compare against.

EF 24-70 f/4 + adapter is a staggering 10g heavier than the RF 24-105 f/4.
Maybe the RF lens has more of the weight closer to the body?
I have the adapter with the control ring. so it's another 20g on top of that.
But I like the fact that puts the control ring right next to the body, as opposed to being at the far end of the lens.
That makes sense to me, but then again, I don't know ant better......
Hi All
I decided to use my existing ef 24-70 f4 shot at 70mm on the R5 and then with a overlay of a fov table I have created cropped the 70mm image to 105mm eqv at the R5 pixel resolution and did a bit of pixel peeping. The results on this lens combo are very good.
So cropping into 105 eqv there is no descernable quality drop. 45 mp certainly gives you some latitude and allows for a one lens hiking setup. With the RF 28-70 u can swing the lens left middle right for a wider view or crop in post for a 105 eqv.
So the only issues is that I dont know exactly how the RF 28-70 stacks up against the EF 24-70 f4 but was told on this post that the latter would be hard to beat. If I go for the former, there is a 40mm difference in combo length, which means I can place the camera + lens combo in a smaller camer bag as a unit as opposed to breaking them up into two leather lens pouches and there is a 239g saving in weight.
Another more technical review from Christopher Frost is out, covering

The review by Klaus at opticallimits (former photozone) is out. I have the lens and I’m a bit surprised by the very low overall rating. Sharpness at 28..40mm is excellent over the full image circle, but at 70mm the corners are dismal and don’t improve much when stopped done. The bokeh is harsh in the background. So far I experienced the bokeh as a surprising strength of the lens.
Some images from a trip to Japan last November. I will group them by focal length. Most are f2.8. All with Canon R8.
They are not meant as unedited review images, but are my memories of my beloved Japan.
Let’s start with 28mm
