Great video! I watched several others, but yours cleared up a lot of specifics that others didn't cover, so thanks for making!! I had the same question someone else had about which focal length to put a zoom on vs a prime. Glad they asked.

Great, thank you for this! I have noticed that some of my photos are starting to lose sharpness, but are actually showing a tiny bit of movement even at fast shutter speeds and with image stabilisation (Vibration Reduction). Is this due to the lens trying to focus on something which isn't quite in the same place as what I'm trying to focus on?? (If that makes sense?!) Thank you!

Thank you very much for this tut. Where exactly did you focus,right on the 0 line or on the big square? Thanks again

On crop sensor camera does we need to multiply focal length or keep as it is.

Thanks ED. Could you please advise how does one calibrate using Manual Focus instead ?

Will this work with a Canon 6D? I can't seem to locate the fine tuning option in the menu.

Welldone, mate!

What happens when you put on a different lens after calibrating one? Will the camera use the value of the previous lens or will it remember the settings for each lens?

The camera stares the information and nows which lens you have attached. most cameras can stere a lot of lenses and if you have a super old lens from say the 70's then many cameras have the option to manually save a calibration and name it for a specific lens.

Awesome video! Exactly what I was hoping for. I just have one quick question and you did address it in the comments below but i just want to clarify. So for telephoto lenses (lets take the canon 24-70L for example) you'd do this test at 24mm and another at 70mm and you said you'd split the different. So for example if at 24mm I was back focused by 2 and at 70mm I was front focused by 3 would I just adjust my camera focus +1 or +2? Thanks! Again- great video!

Does a crop sensor affect the focal length to distance relationship?

Hello. I use a Panasonic Lumix DC-G9, and all of my lenses except my maco lense are the Lumix Leica line. It seem to be spot on. However, I use it for large landscape photography, usually under the circumstances that a chosen focal pattern will cover large areas making it sometimes dfficult to pinpoint the direct spot of exact focus. While I am sure you are aware that shooting M4/3's changes the situation a little bit. I have never seen a calibration setting in my menus but I still want spot on focus when needed. If the G9 does in fact have a calibration setting, to which length do I set up the equipment? A 12-60mm crop is actually the 35mm equivalent of 24-120mm, the 8-18mm converted to 16-36mm, the 100-400mm is at 200-800mm and last the 30mm macro prime out to 60mm? Can you offer any advice? Thank you.

Super happy you liked my explanation. Sometimes things like lens calibration can be a tough point to get across. important to do though.

Perhaps the best video I've seen thus far on this subject. Wish that the "ruler" numbers converted to adjust in the camera, seems like its a try till you get it thing instead 2 equal 2, 3 equal 3 etc on the camera

Sooo I shoot with a Canon Rebel t5i, and I am wondering can I still do this? I heard that I have to send it into canon or a camera shop because I don't have the AF mode or something like that. So do I have to pay someone else to do this, or can I still do it on my own?

What distance should I focus for an infinity distance calibration?

In this scenario you would have to understand how it’s off and focunaccoringly. If you camera is front focusing then focus on the ears. If it’s back focusing then focus on the nose. Not the perfect fix but better than nothing.

Any tips on calibrating zoom lens?

I think that also the camera should be levelled as horizontal as possible to get a strait line with the device.

What about zoom lens, which focal length should I choose on my 18 to 105mm?

@clearlyed

6 жыл бұрын

for this you should do the lens calibration at both ends see what you come up with and then split the different. then test again in the middle. with cool lenses you have to compromise but usually it will be front focussing or back focussing at both extremes of the zoom with one end being a little more extreme than the other. so just calibrate you sense in the right direction. Definitely works

How about for crop cameras? Do you need to multiply the crop factor to the distance?

@clearlyed

6 жыл бұрын

For lens calibration on crop sensor cameras you jus have to do the calculation for the actual focal length that your lens and camera combination gives. so if you are using a full frame 50mm lens on a crop sensor your focal distance would be between 75 and 85mm (depending on brand). you then just use this numbers for your lens calibration. If its a lens made from crop sensor cameras then just use the focal length written on the lens.

Do they make a machined version?

This might not be relevant to this video, but the shutter on my 5d classic has a 5 second lag. It's a new camera to me so I'm not very familiar to the settings. Any help is appreciated!!

How do we calculate the minimum distance for a crop sensor camera. A 50mm will be (50x1.6)mm on a canon crop sensor.

@clearlyed

6 жыл бұрын

you would just do the calculations at the focus length you camera and lens combination works out. So at 50 mm on crop is somewhere between 75 and 85mm so you use that number to do your calculations for lens calibration. I hope tis helps.

Nicely done. Re: mirrorless cameras, hope you don’t mind that I’ve put my comment here instead of as another in the thread below regarding mirrorless. Don’t want it to get lost in the verbal tree. Sony mirrorless cams (e.g., A6500, A7R2) have an AF micro adjustment feature to calibrate AF for certain adapted lenses - front/back mis-focusing is addressed. Not as widespread a prob., but just to set the record straight, it’s sometimes needed for mirrorless. (Can’t speak for brands other than Sony, but wouldn’t be surprised.) My guess is that the kind of product you describe would be a reasonable tool for same issue. Would appreciate your sponsor’s reply. BTW, miss the intro dance steps . 😀

for lens calibration of telephoto lenses its exactly the same. so a 400mm would nee to be calibrated at 400inches. That being said this is not vitally important for lens calibration, its just ideal. if you don't have the space and need to be slightly closer ten thats just fine too.

Hi Greg, great video. I use the lens call several times a year to do lens calibration checks. One thing though, I think your conversion rate in metric is wrong. 2500cm = 25m not 2.5. Thanks again for uploading useful and interesting videos.

ever camera is sent out within a tolerance. Nikon or cannon might say for example that the body can go out with a tollenrent of plus or minus 2 on a scale of say 100. the same goes for a lens. Remember nothing is perfect. so if the body is say +2 and the lens is also +2 then your focus is going to be off by +4. this is noticeable for sure. I have lenses like this and a calibration fixed it. I hope this made sense and answered your lens calibration questions

@RomboutVersluijs

@clearlyed

6 жыл бұрын

I think you are misunderstanding. You are correct that with he value above the lens would be off. which is why we calibrate. Lets go back. Inside a factory where thy make cameras not everything comes out 100% perfect, thats impossible. so instead they have developed systems of tolerance. if a product is within a certain tolerance then its acceptable to be shipped. The same goes for lenses. Not all lenses are perfect and even if they are slightly off they can still be within the factory accepted tolerance. This however means that our systems can be off. So in the explanation before a camera leaving a factory may be slightly cack focussing but still within the tolerance so gets shipped. A lens might also e slightly back focussing but still wishing the tolerance so gets shipped. put these together and the problem is multiplied and your critical focus is off. This is wy we calibrate. Also, over time equipment drifts, if you pump it, drops etc this can all effect the level of lens calibration. So again. if the tolerance fro a fact try was +2 on the body and _4 on the lens. it would be off by +4 you would see that in the lens calibration process in this video. So you would out it back by -4 for perfect focal. I hope this makes a bit more sense. Im not sure my first answer was the best way of describing.

I have done an odd experiment with 6D, SL2 Canon and MFT Lumix - where I am shooting close-ups and trying to evaluate how sharp the lens or sensors are - my comparison is based on me shooting FILM for many many years - and I am not impressed with digital sharpness. I've tried using autofocus as well as manual - and nothing compares to slide or color negative film sharpness - IMHO. AM I imagining things or is this also a complaint with everyone. I have used prime lenses, zooms, Canon, Tamron, Sigman lenses - and nothing is as sharp as film. I will say that out of the 3 cameras - the 6D produces sharper images than the SL2 or MFT. Any feedback is welcomed. I can't believe that every lens with every camera is out of calibration. Not all systems allow for calibration.

the 25cm formula is wrong when I convert my 105mm lens to m it gives 26.25m?????? 105x25=2625mm=26.25m

If my images already look sharp enough do I need to bother doing this? I don't really want to have to buy an extra gadget. I don't have an expensive camera either. It's worth knowing about in future I suppose if I notice my photos are out of focus.

To be honest this is snot super critical. If you are a little off it won’t effect the calibration. Ideally from the sensors but the extra crew cm of a lens won’t effect it. It’s just a general rule for camera calibration.

Just a comment on that cause my canon750d also can not calibrate. However think of it this way. if you perform the test and learn your lens is front focusing by x then at least you could say when I focus, I will focus on the ear and then the eye will be in focus. Basically if you cant calibrate it you can at least learn how to work with it. Also you can do this with a simple ruler set at 45deg on a long table. No need to buy anything. Try it! and learn. :)
