I'm kinda liking my Canon 300/2.8, I can't imagine that a zoom lens comes close. I also like my Sigma 135mm Art, last I looked DXO had not tested it.

While I love my 300/2.8, it is not a "general purpose" lens which the OP is asking about.

Zeiss would be among the best. Sony's G-Master is in the running. But, who makes a sharper 70:200mm lens than Nikon's 70-200m f2.8E FL ED VR. I have checked lenses quality, occasionally on DXO Mark. I have a Zeiss lens embedded in my Sony pocket camera. It is amazingly sharp for such a small camera. I must admit.


I would add the Canon 70-200 IS USM L III lens to this list if we are discussing that focal range.

Yeah you're right, I have a tendency to not fully read, my bad.

The sharpest lens in photography is the one that is currently on your camera.
A GOOD photographer can make any lens SHARP.

Don't get overly hung up on DxO test results as they are done on an optical bench with the camera firmly secured. Almost impossible to replicate that in "real world" shooting. Plus small differences in numerical results may be almost imperceptible to the naked eye...The technique is what will give you the results you desire in many cases. Beware also as the "sharpest" lens may not excel in other areas of measurement....

Or what computer you use to process the images? lol

My sharpest lenses are the 70-200mm Nikon f/2.8 VRII and the Sigma Art series, 50mm, 135mm, and a 24-35mm zoom

I agree, DxO scores are nice, but it has always been and will continue to be the photographer that makes the difference.

Depends on the use.

A lens that is allowed to capture focus in ideal conditions (like in a DxO test) might be sharper in the abstract than another lens. However, if that other lens captures focus faster in the field, it may result in a sharper final image under certain conditions. Conditions such as sports or BIF or motor cross or children playing at a backyard party. Of course even that will depend on how well the camera body handles the lens and what AF options are used.

Questions about the relative qualities of a lens (or camera, or flash, or....) without information about the use, shooting environment or other aspects of the camera system are likely to yield answers that may lead to poor choices for your particular situation.

I could debate the relative qualities of a claw hammer vs. a ball peen, but unless I know what you want to use it for it would be pointless. By the way, neither hammer is particularly good for getting a smooth cut through a board.

As Blenheim Orange suggested, online reviews will give you good info.

My newest Zeiss Milvus 85 is terrifically sharp... with zero distortion, but i bought it for its out of focus -bokeh effects as well as its distortion free portraiture effects.

All purpose lens for me is a wide angle 21 prime ( also a Milvus) - because images taken with it are the only ones where i feel like you could almost stick your head in the print and look around behind the frame- landscapes taken with it give me the impression i am looking out a window. I don't prefer the compressed backgrounds of longer lenses... unless, of course, that is what i want- or if i am taking a portrait, product etc.

In fact i only own primes. Because sharpness come into play most often in big prints.

In the hands of a perfectionist, perhaps it is.

Sharpness is subjective. By this I mean that it is not measurable. You can measure with precision a lens' acuity and contrast. But there is no accurate measurement for "sharpness". This is mainly because the perception of sharpness is affected by viewing distance, subject matter, camera resolution, image magnification, and above all a person's eyesight. I am aware that DXO rates a lens with regards to "sharpness" but they are using a subjective determination, and a comparison to a "perfect" or theoretically flawless lens, and they use P-Mpix, or perceptual megapixels to rate the performance of a given lens on a given camera and how it compares to perfection, assuming that the perfect lens returns a P-Mpix number equal to the camera's mp count. So, if a lens shows 21 P-Mpix on a 24mp body, it is telling you that on that body, that lens is providing 21 of 24 mp performance, or 87.5%. If another lens is tested and its P-Mpix score is 12 on the same body, then you are getting only 50% of the camera's resolution.

So, when you say something like "Zeis [sic] 24 to 70 or is it 24 to 80 2.8 is the sharpest all purpose lens available" what exactly are you referring to as sharpness?
Sharpness is subjective. By this I mean that it is... (show quote)


👍👍👍. There are many, many superb lenses - there is no such thing as one lens sharpest for all purposes and on all camera bodies.

Leica Summicron APO 50mm f/2 ASPH is the sharpest lens ever made that you can buy on the open market.
Period....
