Canon 180 L macro on Canon 5dsr

Gibio — Wed, 30 Jan 2019 18:37:16 GMT

Hello, I'm writing from Italy. I would like to buy a very good 180mm macro. I shoot with a Canopn 5DS and I've read that Canon doesn't reccomend the 180L on a 50MP camera.

Does anyone have a first hand experience with this combo (5DS or 5DSr)?

I shoot details in ancient paintings so I need sharpness even on the edges.

Thank you

Where did you read that Canon does not recommend an L lens for a 50MP camera?

I see that that both 100mm macro made the list.

Obviously, it will work, it *might* be the limiting factor in resolution. What aperture do you usually shoot?

I usually shoot at f8/f9.

I have experience with the Canon 100 usm (not the L); it's an old lens like the 180, but I'm satisfued with the results. If the 180 macro is like the 100, it will be fine fine for me.

i know that the Sigma 180 os 2.8 is better for sharpness and resolutiin but it's really heavy

At f/8 or f/9 it probably does not matter, the lens is improved by stopping it down and diffraction is starting to kick in, anyway.

The combination of the EOS 5DS or 5DS R and EF 180mm f/3.5L Macro USM works very well, but I would only recommend this setup if you are using a tripod.

For the OP's stated application, he will certainly be using a tripod. When photographing paintings, both the perpendicularity of the line of sight and the angle of incidence of the lighting must be carefully adjusted to avoid weird reflections off of the paint. The brushstrokes of oil paint do not result in a planar surface, and getting the lighting right can be very tricky.

I never shoot handheld, always on tripod.

Do you have personale experience about this combo?

I know very well the tecnique to photograph painting. I need the longest macro lens because more is the distance and less chances of light reflections on the paintings (expecially the oil paintings). I'm just looking for the best tele macro lens. I've read everywere that Sigma 180 2.8 OS is way better than the old Canon but it's very heavy (1.65 kg) and I don't need a 2.8 lens and image stabilization. So what I'm looking here is tp know if the sharpness and resolution of the canon 180 is good enough for professional photos

It is an L lens.

Here is Ken Rockwell's review:

Thank you. Yes, it's a L lens but Ken Rockwell tested it on a 5D III that has 22MP.

If I had to use it on my 6D I would buy it immediately.

Why not rent one to check it out.

"I shoot details in ancient paintings so I need sharpness even on the edges."

Are you trying to do frame filling shots? I would think that alone would be a bad idea for best IQ. Leaving some significant cropping room would be my first choice no matter what lens I was using. You do know the working distance with the 180L, which is a lens I really like, is going to be greater? I have not used one on any of the super hi-res 5D models but on a 5D Mk III, it is nothing short of magnificent.

Obviously it is. But I think what you're really asking is whether the sharpness of the lens could be a limiting factor in achieving the maximum resolution obtainable with a 5DS. Apparently some commentators think it could be. But even if it were, the advantages of the lens, notably its longer focal length, could outweigh that limitation. But in trying to resolve that question, you're asking the members of this forum to make a very subjective judgement that, frankly, only you are qualified to make. If you can't rent the lens and try it, maybe you should buy it anyway. Sooner or later, you're likely to encounter a situation where you'll be glad you have it.
