Lens Sharpness - A Subjective Matter? What's the best way of determining if a lens is really in need of professional adjustment?

Tom covers this well, but I'd add that you'll want to select the center AF focusing point only...don't select the whole array. I was irritated by focusing issues on my new Canon 7D until I went back and checked the focus points. Sure enough, on large-aperture portraits it was picking out the nearest points first and not providing enough depth to keep the whole cubject in focus. I switched to running Av only and with the ceter focusing point only. Much better results.

Do a little side by side comparison, and see for yourself. The common believe in the past was that in lens IS was better, but I think with proper technique either one will work. CWDaly claveldaly.com

The image should not be blurry. Have you checked to make sure there is nothing on the viewfinder area...there is a red dial that can change the focus but i wouldn't think it would be blurry even if that was off slightly.

That depend on what lens that you have with the camera. You could read the letters stamped on the front ring of your lens. Every lens should have its focus length, F stop and filter size clearly marked.

It really depends on the focal length of your lens. What type of lens do you have?

Bernard is correct I think. Any modern camera that meters through the lens *should* be fine but you may not like the results and may need to adjust a bit.

Not that this will be of much help, but I'm with you. Ordered a 24mm 1.4 (later returned) expecting the same jaw-dropping results I get from the 85mm 1.4 and it's just not there that I can see. As far as your suggestion of getting closer to your subject for pop - sure, a wide angle lens will really exaggerate the perceived depth of a shot. That's how I'd roll with it for the most part; 2' from the subject (more for DX frame), avoiding top and bottom when shooting vertical (unless you want that edge distortion; maybe not so bad on DX). The sharpness you're looking for also won't exist until you get close enough to your subject to give eyelashes and things of that nature some pixels to work with. At 85mm, it pulls these details in and paints them across, say, 5% of the frame or more. With the 24mm you may be talking about less than 1% of the pixels dedicated to what you're looking for details in. I've seen some REALLY spectacular night landscape images that were made with this lens. Also, the bokeh that lens produces is right on par with the 85mm. The issues I had with the 24mm (and the reasons I returned it) were failure to find focus at 1.4 no matter how much I helped it along and a general lack of spectacular sharpness at 1.4. At this end of the price spectrum, this has to be gold. It's real close, and quite nice at 2.8, but so are lots of lenses at 2.8. That said, I've still got this lens on my mind. If it were a 20mm 1.4 I'd just suck it up and do it. At 24 there are some other close options out there.

It depends on your equipment and needs. My suggestion is to rent one from BorrowedLenses, they do have it and try it out before buying. I have done this with some recent L series lens purchases. It was much easier to make a decision on those fat lenses.

The only adjustment on mine is up/down. I have never needed to adjust focus. My picture is very clear and I am satisfied with it.

My DP1m seemed to be essentially as sharp as it could be around f5.6, from center to edge. It is never as sharp on the edge as the center, nor quite as good of a performer as the DP2m in that regard, but I concur with the previous answer that it is of little concern in real-world usage. I used it without qualms, at any aperture, to be honest (simply choose the aperture you require for DoF and shoot). It's an excellent lens.

This would be a good short term solution for increasing focal length I believe. No doubt you've checked out the longer focal length lenses and you can spend a whopping amount on them!

I've not had a problem with blurring due to vibration when using my lens and besides because of the nature of the beast lenses with that short of a focal length don't really require a Vibration Reduction feature because they are used for indoor shots or landscapes when you would most likely be be using a support of some type.

It may also be the case that you are looking at used or refurbished lenses. I bought one used, it is like new and an excellent lens for low price. Best regards

This is a question that should be answered by the manufacturer, unfortunately, they are hard to find. I have known several people to try other lens. Most tell me that it was not worth the try. One even damaged the main board in the effort. All said that there were some aberrations.

Check out photography-on-the-net forum - some discussion there. I have used the 10x zoom to check focus, but with the incredible depth of field for this lens, it is seldom an issue.

HelloNot, but the truth which does not make much difference, this lens is worth what it costs.Regards,

no, but an amazing lens - sharpness and color rendition is as good or better than any pro lens out there. i am a pro for 35yrs, this is a great lens.
