Magnification question - EF-S 18-135 STM lens with Canon 25mm Extension Tube II

If the minimum focus distance with this lense is 15.4 inches and I were to add the 25mm extension tube, does that mean that I can go closer to the subject, or is the 15.4 inches still minimum but the extension tube simply makes the subject look larger? And, how much larger?
I've read some guidelines but I'm still not getting it
I'm looking to use one lens for nature photography and would love to add a lightweight macro option (using a T5 camera).
Thanks

I saw that calculator earlier, but I didn't understand how they could show the new MFD (or in this case, CFD) without knowing the previous, based on which lens you use. Is the CFD the same for all (non) lenses? I guess I always assumed that the MFD for any specific lens depended on the internal elements of the lens.

Lens correction profile for the Canon 18-135 STM lens in Lightroom 5 ?

How or where can I get the lens correction profile for the Canon 18-135 STM lens in Lightroom 5 ? In effect he is not available in my list of correction lens so my lightroom is up to date apparently :/
Thanks in advance for answer.

There are two types of Lens profiles - raw and JPEG. It looks like you are trying to process a JPEG image and Adobe has only provided a raw lens profile for the 18-135mm IS STM lens.
You have four options:
1) Check for available lens profile using the Adobe Lens Profile Downloader. I checked and a JPEG lens profile is NOT available for the 18-135mm lens.
2) Follow the procedure outlined by Steve Sprengel in this post:

More detailed instructions here for a Pentax lens example:

This allows using the available raw lens profile with JPEG images. To my knowledge Canon DSLR cameras do not apply distortion correction to JPEG images, so the raw profile should work well. You can check this by shooting raw+JPEG and comparing the two images inside LR
3) Create you own lens profile using the Adobe Lens Profile Creator. (A complicated process, but it can be done!).
4) Start shooting in raw mode or raw + JPEG mode, which will allow you to extract the most benefit from LR's processing controls.

LR 4.2 RC Canon 40mm and 18-135 STM Lens Profiles Not Installed

I have installed LR 4.2 RC but when I check Lens Profiles these lenses are not listed although ACR 7.2 is supposed to be supporting them. Can anyone tell me where I can get the profiles for these lenses and what is the proper procedure to install them?

I just figured out what I was doing wrong. All I had to do was open my CR2 RAW file in the development module and select the Lens Corrections Tab and checkmark the Enable Profile Corrections box and my Canon 18-135 STM lens profile was activated. Thanks for the replies.

Lens correction profile for the Canon 18-135 STM lens?

How or where can I get the lens correction profile for the new Canon STM lenses?

I see that lens listed in the release notes for the final Lightroom 4.2 update that just came out a few hours ago, so it looks like the answer is to download the update.

SOME (3-4) MINOR DENTS ON THE BAYONET OF NEW CANON STM LENS

I have bought a new Canon 70D with 18-135 STM Lens kit.
I have noticed some (3-4) minor dents on the bayonet of the lens?
Is it possible for a new unused lens to have some minor dents on the bayonet of it?
Thanks.

I guess it rests on what your definition of the word "dent" is. WOW, where have I heard that phrase?
1. a hollow or depression in a surface, as from a blow.
It should not have any "dents" in it. It will not get dented by removing and installing the lens. Period!

18-135mm STM lens...Opinions?

I'm considering a mid range zoom for my T3i, and wonder if the STM version of the 18-135mm has
any advantages over the 18-135mm II IS lens?

I do not own the 18-135 STM lens but every thing I've read is that is is a very good lens in its class. The STM designation is a quieter motor which benefit video shooters. Since you have the 18-55 lens already, you only gain 56-135mm in focal length. You might consider a telephoto zoom lens with a longer short end instead. If you have access to a camera shop, I would look through a 135mm lens to get a feel if 135mm is long enough for your needs. Otherwise I would consider a longer zoom lens.
Not knowing what your budget is, I would consider the 70-300 IS which is about a $100 more and for an additional $100 you can get the very sharp 70-200L f/4 but it does not have IS. If you find that 135mm is long enough, you might find that the best option is the 18-135 STM since you can zoom from wide to medium telephoto all with one lens.
Your 18-55 is good for landscapes and portraits so you got that covered. Good luck.

Problem with the AF of my new 18-135mm EFS IS STM lens

Hello,
The lens came with the EOS Rebel T5i bundle.
The auto focus is working incorrectly, focusing closer than the detected area. This is happening when I use the viewfinder. When a picture is taken using the “direct view” (LCD display) it focus correctly.
I didn’t use the camera a lot since I bought it, now looking the first pictures I see that this problem is happening since I bought it.
I changed the zoom lens with another Canon camera and then my new Rebel T5i works fine and the same problem happens with the other camera, therefore I’m sure that the problem is in the lens and not in the camera body.
The out of focus is more noticeable when I'm taking pictures in 18mm position to an object farther than 2 meters but it is happening in any zoom position. It is clear when I compare the same picture taken with the viewfinder with one taken with the LCD Display.
I updated the body firmware and the problem continues.
Is it possible to update the lens firmaware? I couldn’t find them in the canon webpage.
I will go into an important trip next week, therefore I will not have time to send the camera to repair.
Any idea?
Thanks!

You may want to rent a lens for your trip and get this lens to service.
You'll want to be sure it really is a problem with the lens (it sounds like it is from your description). Test the lens against a "flat" target (such as a wall). You can hang something on the wall with high-contrast (newspaper works great) and put the camera on a tripod. The idea is that (a) the camera is definitely not moving, (b) the focus target is definitely not moving, and (c) the target is flat and there are no distracting objects in the field of view so it's not possible for the focus system to decide to lock focus on anything OTHER than your intended target.
Next... deliberately turn the focus ring to put the camera out of focus (so that the camera HAS to move the focus). This is mildly tricky with an STM lens since there's no mechanical link from the focus ring to the lens -- it's electronic. The lens only accepts focus input when focus is active (e.g. half-press the shutter button, etc. to wake it up.) I run focus all the way in and test several times, then run focus all the way out and test several times (that way it has to move focus in both directions.)
If the lens is consistently focusing closer, then it will need service.

Rebel T4i Kit with 18-135mm Lens, STM lens like Amazon?

Amazon has it for the same price, but I noticed it is listed as the STM lens, which is a new lens specifically built for the t4I.
Bestbuy has it listed for the same price, but doesn't list it with STM.
No point in buying the same camera with an older lens from Bestbuy when you can get the same one from Amazon with the new lens.
Hope this can be clarified.

EF-S 55-250mm F4-5.6 IS STM Lens

Can the EF-S 55-250mm F4-5.6 IS STM Lens be used for macro. The resin I ask is because I am new at macro and don't know if I will enjoy it. So I don't want to get a dedicated lens as of yet. So I figured if I can use this lens for it I can also use it for other things as well expecially if I decided not to peruse macro or if I do wish to this one can still serve a perpus.

Hi Jake.
The 55-250 is not a macro lens, and not even one of the ones that are kind of close to shooting macro.
You can look into extension tubes, which mount along with a lens if you do not want to get a dedicated macro lens.
Dedicated macro lenses are fixed focal length lenses (primes) like 60mm or 90mm or 100mm or 180mm. There are no macro zooms as far as I know.
That does not mean you can't use extension tubes on your zoom lens, it will just be a little tricky. You will want to set a focal length and leave it alone - don't zoom around- or it will change your minimum focus distance which might mess you up. With macro you want a long lens anyway, so just peg the zoom at the 55mm end and leave it alone.

18/135 Kit lens

I am impressed with how good the 18/135 kit lens is. I have 3 L lens and I am amazed at how the 18/135 performs.
Canon 7D 18/135 at 60mm:

For $80? Absolutely. Welcome to SLR, things won't be that cheap again! I've got filters that cost more than that.
The 55-250 isn't terrific, but it's better quality than the 18-55 IMHO. I actually still use mine (on my 400D) as I upgraded a bunch of ultra-wide, wide, macro, and prime lenses and never pulled the trigger on the 70-200. It's slow, it won't win any sharpness awards, but it's infinately better than nothing. At $80 it's kind of a no brainer.
Edit: the main difference between the 18-135 and the 55-250 is the focal length. I can't comment on the IQ, never been much a test charts kinda guy, but I'd suspect in the real world that performace will be along the same lines. But 250 is significant reach over 135.

Parfocal-ness of the Sony 28-135 G Lens

The lens is of course not parfocal, not optically / mechanically. The camera (or lens itself) constantly corrects the lens groups arrangement to make it "parfocal". In other words, without electronics the lens is not parfocal. This is also the reason why this lens can get by with no back focus adjustement mechanism. Something is off in the way the camera corrects it.

I noticed some focus issues with my 28-135 zoom lens as well on my FS7. I did some tests with the Canon 70-200mm L-series lens (which is definitely parfocal) and it performed just fine, so I know it isn't the camera. I sent in the 28-135 to have it repaired and Sony replaced the lens entirely. Took the brand new lens right out of the box today and it had the same issues of losing focus as you zoom out. The best way to see the shift is if you turn peaking on and line up a few objects on the z-axis. The focus should move to the closer objects as you zoom out (as long as they are not within minimum focus distance). Here's the wacky thing though - I double-checked to make sure I wasn't in auto-focus mode by switching to auto and playing around with focus there. When I switched back to manual, the lens fuctioned just fine (no shift in the focal plane when zooming). There seems to be some kind of calibration that takes place when you switch to AF, grab some focus with the push auto feature, and switch back. Or maybe I'm wrong. But as of right now, the lack of parfocal-ness no longer exists.

I use Canon 5DMk3 for videos in A/F mode. When will Canon come out with a quality STM lens?Tad

When will Canon come out with a quality lens with STM phase focusing for Canon 5DMk3? I shoot mostly videos. in A/F/
The 1.2.1 firmware update didn't do it.
Tad

Yes, sorry. I did realize I didn't specify exactly what I shoot.
I do a lot of car-related things. Car photoshoots, races, etc. I'd like to delve into portraits and such more upcoming too.
The races are easy to do, so long as you have a fast camera and a good lens. Even going from my old Nikon D60 to the faster Canon 60D proved very helpful. I am also pretty good at the focus pan where you move with said object to blur the background.
My real issue with the crop sensor cameras thus far have been the noise levels. I do a lot of shooting in low-light. But I figure a couple proper lenses a good tripod, and some time experimenting could help that.
I do like the idea of the T5i as it's so cheap. At only $600 on the body, that would give me plenty of wiggle room to fund proper lenses. And I suppose that if I went that route, I could always just end up picking up a 7DII as my go-to when released, since the T5i will obviously have it's limitations.
But at the same time, going right for the 70D would also be a solid choice as to it's benefits, larger sizing, etc.
Although I'd love a 6D, it's probably better that I stay away from FF for now until I get steady pay from shoots. I know me, and I'd take myself broke buying proper lenses.
The 60D seems like it's still a good choice, but kinda going backwards from the others. And the 7D, same thing. Although still a great camera, it seems to (at least for me) have the negatives outweigh the positives at it's price point.
So it seems like it's been narrowed down to the T5i and the 70D.
FYI, I don't have a ton up yet as it's been recently created, but feel free to check out my page for a couple references of what I shoot. It's below.
Also, on Instagram, I'm "averagewhiteboy" as well. I have a Flickr Pro account too, but I don't think I've updated it since going Canon.

Is canon EF 24-85mm F3.5-4.5 lens is compatible with canon eos 6D ? is it work fully automatic ?

Yes, that lens will work normally on the EOS 6D with all automatic functions intact. Any Canon lens labeled as "EF" will work on the 6D, but lenses labeled "EF-S" will have strong vignetting (darkening in the corners of the shot).
Actually... "EF-S" lenses will not even mount. There's a lip on full-frame bodies designed to prevent EF-S lenses from being attached. It's not just a question of heavy vignetting and severely degraded image quality at the edges of the frame -- there's a risk of the reflex mirror hitting the rear-most element on an EF-S lens (remember... full frame cameras require physically larger reflex mirrors).
Any "EF" lens can be used. Any "EF-S" lens must not be used (and will not fit). Also, there are a few special purpose lenses such as the MP-E and TS-E lenses which will work with the 6D as well.

Macro lens for Canon 5D Mark iii

I'm taking a Class with NYIP and need to submit a macro photo. Not sure I really want to get into macro so I was hoping for suggestions on cheaper a lens or tubes. Any suggestions?

How much magnification do you need for this project?
Buying a set of extension tubes will cost you less than $100 and allow you to get 1:1 Macro magnification with almost any lens you have now.
Another cheap option is to use a reversing filter ring to mount a 50mm lens backwards onto to any lens you have now.
The cheapest option of all is to just hold the lens backwards against the camera body. I just took this photo of a pencil holding an EF 50mm 1.8 up against the camera body.
