Lack of sharpness is not a problem a properly working sample has.

I also found this lens kinda soft with most of my shots. One of th reasons I parted with ti. The people that have this lens and produce tack sharp images are you shooting with cameras with AF Microadjustment?

Hmmm, I'm surprised some people are finding this lens soft.

Here are a couple of photos I took with it a while back as simple exercises in form and texture. Sorry this is all I have handy. They are are hand held in natural light, but they're pretty typical of what I've been seeing from it. There was very little if any sharpening added if I remember correctly.

Have you been getting significantly different results or are you looking for even sharper images?

@FTb

Those look to be fairly sharp. Did you micro adjust the lens on your 6D? How much post if any was done on those pics?

No micro adjustment on this lens.

I just checked my processing and I think there was very little done to the raw -- cropped a little, added a bit of saturation, raised the shadows a tad and then a little sharpening for the screen when converting to jpg. Nothing unusual.

Here's a screen shot of the basic image before the crop and before lightening shadows.

slrgear.com has a good review and blurr chart on the 40mm

It is a very sharp lens on Crops wide open and sharp on FF but with very slightly softer corners. Stopped down to F4 it is nearly tack sharp across the frame on FF.

My own experience is that it is decently sharp but improves enough at F3.2 vs F2.8 that is where I shoot it when I use it.


Hockey and wedding photographer. Favourite camera / lens combos: a 1DX II with a Tamron 45 1.8 VC, an A7Rii with a Canon 24-70F2.8L II, and a 5DSR with a Tamron 85 1.8 VC. Every lens I own I strongly recommend [Canon (35Lii, 100L Macro, 24-70F2.8ii, 70-200F2.8ii, 100-400Lii), Tamron (45 1.8, 85 1.8), Sigma 24-105]. If there are better lenses out there let me know because I haven't found them.

I think for me, it is as much user error as it is a soft lens. I think I have spent the past 7 years with GAS. Thinking if I had better equipment, I would have better images. Now I browse through all of my photos from these years and realize I have some pretty terrific images - from the Ti1, 5D2, G12, SL1, EOS M, SL1 (again), 6D and now the T6i. I won't even name all of the lens that I have bought and sold.

Instead of always swapping gear, I should have spent more time developing my skills with what I had. I have spent the last few days reading articles to learn how to better utilize ISO for sharper images. For now, I am going to buckle down and learn to produce stunning images with my current equipment before adding more.

I did order the Ef-s 24mm pancake lens, only because I want that light, easy set-up. I am going to keep working at this, because I do love taking pictures and editing images. Back to the joy of the hobby.

:-D

That makes perfect sense. you can get good photos with almost anything but the gear is fun to play with so nothing wrong with trying stuff out.

Well, I'm certainly not a pro, but whenever I used the 40mm and compared it to the same shot using my 60mm with similar exif there was no contest to which shot I was going to keep. Granted the 60mm macro is a different lens, but I was always happy with the sharpness and usually compared my other lenses to it and the 40mm didn't stack up, so it was sold.

Great idea. If I were teaching a class in photography today, I'd have students use only a single lens, and one that's not particularly sharp, so they'd have to rely on other things -- like lighting and composition -- to make good photos.

Sharpness can certainly be important but it's only one of several key elements. I see dozens of sharp photos every day that seem to have no other redeeming qualities.

OTOH, even the least sharp lenses made today are significantly sharper than almost any great painting. So we know amazing works of art can be produced without microscopic levels of detail.

Good luck!

My 40 pancake is not particularly sharp, nowhere near as sharp as my 24 pancake. One thing I've discovered though is that the 40 is prone to focus shift. Several goes at AFMA have now improved both sharpness and (it seems) focus shift, though still neither are great. As with other focus shifting lenses, you may get sharper results by manually focusing at the aperture you want to use, rather than letting the camera AF at f/2.8 before stopping down to your selected aperture.

That. I find this obsession with corner-to-corner sharpness bizarre and somewhat forced. At times, it appears to me to border on being ill-informed. People complain about "corner softness" in a lens but the Italian Renaissance masters would deliberately blur the edges in their paintings to achieve the same effect a "flaw" creates in a modern lens. I am certainly not going to think myself their better by seeking sharpness where the entire history of art considers it unnecessary. Sharpness is important, and yes, sometimes it is needed across the frame, but it is probably so in fewer instances than most people believe, and it is certainly not an overarching criterion.

I am glad you said that, because I was thinking I was having trouble with the focus. It is on it's way back to Amazon and the 24 pancake on the way to me. Glad I switched them out.

Now you've got me wondering if you just got a bad copy. Your results seem counter to mine and to some of the objective test data. But, a few other people are reporting experiences similar to yours. Wish you coulda tried another 40mm.

Would it be possible for you to put your camera and your 40mm on a tripod and take a shot or two before you send the lens back? I'd love to see a raw file taken on a stable platform.

I probably did get a bad copy, because I went through the thread for picture samples on this lens and there are some stunning pictures. I was never even close to that. I might end up getting it again, but wanted to start with the 24 instead. I think I will probably end up with pancakes on both cameras most of the time.

Thanks for all of your help.
