The Canon RF 45mm f/1.2 STM, which was announced towards the end of 2025, brought a fresh outlook to Canon's RF mirrorless system. With a price tag of about $469, this small lens (78 x 75mm, 346g) promised to deliver shallow depth of field, beautifully blurred backgrounds, and nighttime performance without the high-end price tag […]

Hey everyone, here's a few selections from a sequence of shots I captured yesterday.

More flowers from today: I didn't see any bird deserving to be on photo.

Cute little ball of feathers. Nicely done, Alan.

The Goldcrest is Europe's smallest bird, weighing in at 5.5g/0.2oz. The Firecrest, which I saw yesterday, is very close in weight and size, but is much rarer.

IMO, sometimes the ‘one lens solution’ is the best tool for the job. For me, when the ‘job’ is a family trip where I want good quality photos including memory shots, but don’t want to detract from time with the family by carrying a bag full of lenses and changing them out, the best tool is often the R8 and RF 24-240mm.

But yeah, if I’m being honest then I will add that I often also carry a fast, wide prime (24/1.4, 24/1.8 or 20/1.4) and the 10-20/4 since that kit fits in a bag small enough that it isn’t excluded from venues (museums, etc.) that don’t allow backpacks.

I went back to the same spot as I saw a Firecrest yesterday, this time armed with the RF 100-500mm as the conditions were so dire between showers. Got in just one shot as a bird briefly appeared for about 20 seconds. And, when I looked at the image - a Goldcrest. (1/200s at iso 40,000), I am tempted to buy a used 400mm f/4 DO ii for these conditions, but it would rarely be used and still cost about £3500).

Checking travel pics from last summer, I realized I shoot so much landscape at 200mm this won't make it. Also in cities and with people I often use apertures faster than 2.8.

ISv and Speedfinder,

Very nice shots, guys.

Traveler · Sunday at 9:43 AM

Would be much nicer to have something like 70-180 (closer to the 200mm and maybe less wide if it makes the lens easier to design). But I get that the diameter of the front element depends… you all know it.

And Canon probably needs to protect their 70-200 (both f/4 and f/2.8) so there must be some disadvantages to that STM lens.

Forgot to add, its a Corn Bunting central Spain

If someone used different lenses and could prove a difference, would it be accepted? Or would people argue that the results aren't meaningful because different lenses. Maybe it doesn't matter because people will just be argumentative.

It would likely depend on the comparison. For example, I’m not sure that comparing the digitally corrected corners of the inexpensive RF 16/2.8 to the optically corrected RF 15-35/2.8 would be valid, because the base quality of the two lenses is very different. Having said that, it is interesting that the digitally corrected corners of the RF 16/2.8 deliver similar IQ to the optically corrected corners of the far more expensive (but also much older) EF 14/2.8L II.

David_B said:
Sorry, I can't help as I don't have the required equipment (a lens that doesn't fill the sensor.)

I see. So you’re belief that optical correction is superior is akin to faith – belief without evidence.

David_B said:
IMHO, to do a proper test you'd need to shoot a test pattern chart, the kind that's used by digitalpicture, dpreview, with all the lines at angles to enable measuring lpmm, etc.

As @AlanF mentioned, I have the same enhanced ISO 12233-type charts used by Bryan/TDP.

Thanks, I didn't know that.

You’re welcome.

For city trips, I take the R5 along with the 14-35mm F4 L and the 70-200mm F4, sometimes a fast prime. For hiking, it depends on the route. Either I take the exact same combo, or I switch the 14-35mm for the 35mm F1.8. The 16mm sometimes gets a place somewhere between my stuff

This year, I have to go lighter because we're now traveling with a kid So, I got the R8 (surprisingly capable camera!!) and I plan to pair it with the 28mm F2.8 for landscapes and such, 50mm (family pics and my kid) and a zoom. I don't which zoom I'll be carrying. I can always take my in-laws 100-400mm (which used to be mine) in exchange for my 100-500mm. I am currently looking to replace the 24-105mm F4 L (too heavy for the R8), but I don´t exactly know what I want. I'll wait and see what Canon does with the third F2.8 STM lens.

I agree, i mostly just use the 14-35mm or 24-105 f4 for hiking with the 100-500 in the bag(its to heavy to have on your neck while hiking), but a 50-150 with the 14-35 would be more versatile, light and still long enough for the ocassionnal wildlife pic

than both a 70-200 and the 100-500

I wrote "optimal" to give the upper limit. Under suboptimal conditions, you still get varying degrees of extra resolution, from nearly none at the real extreme to nearly twice. The diffraction limited aperture for a 39 Mp sensor is f/4.7, as opposed to f/5.2 for the R7. DLA is not a sharp cut off but there is a progressive decrease in what can be resolved as you approach it. There are several posting here who use the RF 200-800mm on the R7 at f/9, nearly 2 x the DLA on not the sharpest of lenses, because they squeeze out more detail than on their FF bodies. An f/4 lens would bring out closer to the best.

While optical correction is bending light, you don't disagree with the statement that optical correction doesn't stretch light. Arguing about bending light is a bit pointless because that's the whole point of a lens - to bend light such that it lands on the sensor.

The light that is digitally corrected to fill the corners when required still falls on the sensor.

David_B said:
Some lenses deal with this better than others. Some subjects are impacted by this more than others. Measuring CA is what a lot of lens test websites do when they shoot specific subjects to measure lpmm, etc. Your generalizations here are no better than mine.

The difference is that I’ve provided empirical evidence to support my points. Have you? Has anyone who claims that optical correction of geometric distortion is inherently superior to digital correction.

David_B said:
Let me make your day: I don't use distortion correction when processing images, I can't even remember when I last used CA correction.

So you shoot RAW, and you don’t use a lens profile in your RAW converter? I’m skeptical. Especially after your intentionally evasive reply to @AlanF.

Still waiting for Canon to develop a 17-55 2.8 equivalent in RF.
That's been my favourite walk-around if I didn't have the 24-105 mounted.
Or a 10-22 as the extra 4mm is handy compared with the 10-18.

If you are often reach-limited and generally cropping to APS-C and below, a 39 Mpx sensor is a huge advantage over a 34-30 Mpx FF with almost twice the linear resolution under optimal conditions.

Is it important to have a fast sensor to prevent rolling shutter? I am not a bird / sport shooter but would assume this camera could be useful to that market but with fast moving subjects it seems like a faster sensor would be better.

Yes but only really if the birds are moving (I've generally only done perched/static bird shots so it wouldn't be an issue).
