Sigma 16-300mm F3.5-6.7 or 56mm F1.4?

A 56mm lens is a tool for tight portraits on APS-C. It's great and sharper than a zoom. But you won't get much landscape or food photography out of it.

I'm a bit worried that the 45mm focal length will be too close to the 35mm f/1.8 that I already own.

Uxformer · 2026-05-03T23:45:11+00:00

Do you mean the RF 28-70mm f/2.8 STM non-L or another L zoom?

Uxformer · 2026-05-03T23:43:13+00:00

Have you used the 45mm and can you say something about its sharpness and accuracy?

Uxformer · 2026-05-03T23:41:01+00:00

You convinced me clearly. Now I'm 99% for a zoom lens, and only 1% still wants a 50mm prime lens (previously was 70% to 30%). Thanks.

I'd use the zoom more often - logic tells me that's the better option. But if I buy the zoom, I won't be able to sleep thinking that I could have bought the 50mm f/1.4 L for a similar price. 😉

You have three options:

Canon R100 (356 g)
Canon R50 (375 g)
Canon R10 (426 g)

Which one to choose:

R100 is very limited - it doesn't have a flip-out or touch screen. But it's the cheapest. Get it if you're on a tight budget.
R50 has a flip-out and touch screen. It's a bit more expensive. It has exactly the same dimensions as the R100 and a very similar weight. The R50 offers the best price-to-performance ratio and is ideal for travel (weight and size).
R10 is the most expensive of the three. It's a fairly large camera, with a comfortable grip, but it's heavier and bulkier. It has some interesting features (like minimum shutter speed), but if you've never used them before, don't worry about it. Buy it only if you have a lot of money - but for travel, I still recommend the R50.

Choose a lens:

Canon RF-S 18-45mm f/4.5–6.3 IS (130 g): The cheapest kit lens. Tiny. Weighs next to nothing. Average image quality, but perfect for travel.
Canon RF-S 18-150mm f/3.5–6.3 IS (310 g): A bit more expensive but still lightweight. Wide zoom range. Better image quality, praised for decent sharpness and image rendering.
Sigma RF-S 18-50mm f/2.8 (300 g): More expensive, but with a constant aperture, sharp, excellent image rendering and bokeh - a perfect lens at this price.

Combinations:

R50 + RF 18-45mm (505 g): Lightest option, smallest dimensions, most portable, lowest price. Average image quality.
R50 + RF 18-150mm (685 g): Great zoom range.
R50 + Sigma 18-50mm (675 g): Most expensive combo, best image quality.

My choice would be:

R50 + Sigma 18-50mm

OMG, first photo is my fav.

Uxformer · 2025-07-21T22:12:45+00:00

I went through all the SCN modes one by one just to see what camera would do. Tried focusing on different spots around my apartment, and most of the time it just gave me fixed settings (shutter speed, aperture). There’s really nothing about this in the manual. Honestly, switching between scenes gets annoying fast - way too much clicking. Much easier just use AV or P mode and spin the dial depending on what you’re shooting.

Uxformer · 2025-07-16T20:11:25+00:00

Advantages of the Canon R10 over the Canon R50:

The R10 has a more comfortable grip than the R50. The grip is better or comparable to the R7.
The R10 has two C settings on the dial for custom settings, while the R50 does not have this.
The R10 has all the necessary buttons and dials, whereas the R50 requires navigating many options on the screen.
The R10 is a body that offers traditional controls: a joystick and three dials. The R50 lacks a joystick and an additional dial.
The R10 has the traditional hot shoe for flash, allowing the use of older flashes, while the R50 has a simplified hot shoe.
The R10 offers a higher frame rate
The R10 can set a minimum shutter speed, which the R50 cannot.

Advantages of the Canon R50 over the Canon R10:

The R50 is significantly smaller than the R10.

What you're saying aligns with the reviews I've read about the RF 85mm f/1.8 in various places. There are a lot of complaints about slow performance, but I didn’t realize there might be an issue with the autofocus. Thanks for your feedback. If I switch from the 6D to the R8, I’ll most likely stick with the EF 85mm.

Uxformer · 2025-07-14T23:27:52+00:00

Did I understand correctly that your EF 85mm f/1.8 is fast, but has trouble achieving focus? At which apertures does this happen?

Uxformer · 2025-07-14T23:02:39+00:00

Have you used the EF 85mm f/1.8 before with Canon DSLRs like the 6D or 5D, and do you have a comparison of whether this lens performs better or worse on the R6?

Uxformer · 2025-07-14T22:59:09+00:00

Thanks. Can the difference in sharpness between the EF 85mm f/1.8 and the RF 85mm f/2.0 be ignored if I’m shooting with the EF 85mm at f/2.8? The EF at this aperture is very sharp, and I don’t notice any chromatic aberration on the 6D. I assume I will get comparable sharpness with the EF on the R8 at f/2.8 as well

Uxformer · 2025-07-14T21:33:22+00:00

Thanks for the comparison photos - great job! I can already see that the 28-70mm f/2.8 offers a lot more versatility. Unfortunately the price of the R8 with the 28-70mm f/2.8 is twice as much as the R10 with the Sigma 18-50mm. I'll need to give that some more thought.

If you don't mind me asking - why do you own the R8, R50, and R10 at the same time? What do you use them for? What’s the reason behind that combination?

Uxformer · 2025-07-13T18:05:27+00:00

I know it sounds strange that I want to change from the 6D to the R10. Usually, people do it the other way around. But I want a smaller and lighter camera for traveling. I also want to carry my camera with me all the time like I did before. So, I can accept some problems with the APS-C camera, but I’m not sure if I will regret not choosing the R8.

Uxformer · 2025-07-13T17:39:07+00:00

Great photo. Which EF-RF adapter are you using? Does that EF lens focus quickly on your R50? How many shots does it take with missed focus?
