Blurry pictures of Canon 70-300 mm IS USM

Recently, I bought a new 70-300 IS of Canon (not the white L). I was clicking famingoes and other waders. Used servo focus and another shot in with a wide aperture aperture priority mode. I was not too impressed by its 300 especially sharpness. Sharpness that I get with my 18-135 STM is much better compared to the 300 especially when cropped. Given that the investment is already made and I can't redeem another lens, also what is the best way out. How can I improve sharpness. What telephoto lens gives the best sharpness. I should send him for a check. It is under warranty. What could be the best option if I were to sell it buy a new one.

After that I got problems, I read on the net that the sharpness of this lens is not good at all. I wonder why Canon always sell or not done something about it. It doesn't have a reputation to save.

I take it as a given that you cannot return a new lens for where you bought it.  What is the number of complete, exact model for the lens that you are talking about?

What camera do you use with the lens?  Some devices have AFMA, Auto Focus Micro adjustment.  Zooms were long to sacrifice the image quality for the convenience of multiple focal lengths, but they got a lot better over the years, especially in the medium price range.

Several zooms perform better and worse, to certain ranges of their focal lengths.  It is not uncommon that telephoto zooms to, suffer a decline in the quality of the image at the upper end of their range of zoom.  However, you may see pictures of the development.

If you take pictures handheld, try taking some of a sturdy tripod, just to see if the camera shake is what you see.  Additionally, make sure that the Image stabilization is turned on when handheld using it and do not move the appliance too fast.

[EDIT]  Can post you a picture of the sample?

  • Discussion questions with rebel eos of cannon during the action of street shootings? Why are my blurry pictures?

    In situations on a tripod or in most other situations my camera and objectives seem to focus well. In a stable situation where the subject does not have many, I simply turn the wheel around the focal point I want the camera to focus on my photos are usually good, but I found that I love street photography and capture people who do things. Sometimes, they are moving toward or away from me. .. I use a wide-angle F2.8 and generally have no worries to keep larger than the focal length shutter speed... I keep the camera autofocus and AWB... So why are both my photos blurry... I don't have time to every shot to lift the unit and turn the wheel to emphasize a particular point if I usually leave a central development... What should I do to get my shots in short without looking through the viewfinder with each stroke?

    Note that the update "AI Servo" difference in mode of development of "One Shot" in terms of what it does when you press the shutter button.

    In "One Shot" mode, the device uses "Focus priority".  This means that the camera will NOT take a hit if the lens is in auto-focus mode until it can confirm that he was able to focus on the selected AF point (or on a Focus point if you let point AF Auto selection) in brief: realize the development is more important than shooting at the precise moment when you press the button.  That's why "focus priority".

    In "AI Servo" mode, the device uses "release priority".  This means that when you press the shutter button completely, the device will take the shot immediately and it will do so if he had time to reach the focus... or not.    In short: capture the shot at the precise moment when you press the shutter button is more important to achieve focus.   That's why "release priority".

    If you quickly press the shutter button to take a picture, the camera will shoot first and development worry later.  You half - press the shutter to allow the device to reach to the point before you fully - press the key.

  • Cannot download pictures from canon SD850 digital camera to the computer it copies all files

    How can I download just the picture of this camera I want for my PC, without having to download all the photos from the camera. Must be a simple step, but I can't find it. I find myself with plenty of copies of each photo, because it downloads all the pictures every time. I have Windows 7, with the Canon camera software and Photo of Windows software on my PC.

    Thank you, Dennis

    Seasons Greetings Dennis...

    I guess when you connect your camera you get the "autoplay" dialog box offers you different choices?

    You need to select 'Open folder to view files' then simply highlight the one you want to copy - click on copy and paste in the desired location.

    If you don't get the dialog box, then go to the 'computer' and the cannon should be there. Once again use 'open folder' and continue as above.

    If that don't get you on track give us one!

  • Webcam on Satellite L655 shows a very blurry picture

    Hi guys

    I bought Toshiba Satellite L655-158 last Sunday. Just checked the webcam. Used via Skype and everyone complains about the quality of the image. I tried to use an another older Dell laptop on the same internet connection (because I know that could have been because of the internet connection speed), but the picture quality on this one was very good.

    I'm tempted to return the laptop but I thought I'll check if there is a solution available on this forum.
    Thank you

  • iPhone 6 more takes the blurry picture is long distance

    Someone at - it a similar problem as mine?

    My iPhone more than 6 can take clear picture "close-up", but not "long distance". I can't take pictures of the beautiful views, or part of the pictures.

    I am sure that the camera lens is clean and I also re - start my phone before, but nothing has worked.

    This phone is out of warranty Apple 1 year, and I don't know how much it costs to fix this

    I don't physically drop or damage this phone, and why it will happen. Is this some sort of defective product?

  • The design of electronic signature in Illustrator and Dreamweaver but get blurry pictures?

    I am currently designing an email signature using Illustrator and Dreamweaver. I designed the signature with dimensions of 220px 600px, it uses a logo file linked, some layers of text and a few png society accreditation. When I look on the screen is fine, but as soon as I slice it and try and "save for web" the images are blurry, even with a maximum size of file in JPEG at 100%.

    Does anyone have advice? most of the forums say just to play with the percentage of quality until you get a balance between file size and image quality, but poor of mine 100%.

    Under preferences PS > leaders & units, you can change the new settings predefined document from 72 DPI to 300ppi.  First of all, I have all projects on a very large, high resolution canvas.   I can always down-scale images without much trouble, but enlargement of the artifacts of causes (blur).

    Save for the (former) Web feature IMO was poor both compression and optimization.   I was never completely satisfied.  It is good to see that PS is finally taking steps to get away.

    For the vector shapes and text, file > export as > SVG produces the highest quality and you can cut SVG without loss of many details.

    For images raster, file > export as > PNG or JPG seems to work well if your images are of sufficient size (total pixels).

  • Why are my blurry pictures?

    A time to return my camera was not made well autofocusing. I sent it in for repair. I have not used much lately. I also have some flash photos of my granddaughter last weekend and they are not to the point. What would be the most likely cause of them not being is not in focus. Any help would be appreciated.

    Thank you

    Check that the AF / MF switch on the lens is set to AF. I've been known to switch to MF while installing a lens every so often.  Also according to the objective, some have remote control switches and again I she had set out for many & tried something close to forget to change the position of the switch.

    Hello jscharmann,

    Thanks for choosing Microsoft answers Forum!

    I would check my transitions and effects because one of the consequences is that you can image blur.

  • blurry photos and no savings

    Just today, I find that I take pictures and I can see them in the lower left corner, I can look at the photo - but it is blurry - and it does not save to camera roll. Front and rear camera. Each edition or the share option is grayed out. I rebooted with no luck.

    Hello

    Although you have described a problem with photos taken with both cameras, note that there is an iSight (rear camera) program alternative for iPhone 6 Plus.

    Subject to the terms of the program, if the rear camera on your iPhone is the production of blurry pictures and is located in the eligible number, Apple will replace the iSight camera, for free.
