Super wide Zoom and Super telephoto Zoom for 6D without vignette effect

I have a Canon 6D Full frame camera. And I just bought the 24- 70 L II USM lens. 
To complete my kit, I'm looking to invest a super wide zoom ( as low as 10 going uptil 22/ 24 mm) and super telephoto above 70 mm going uptil 300 mm (both preferably L series USM, with wide openings along the full focal range) 
Before I make the purchases I want to be sure which lenses do NOT have the problem of vignetting AT ALL. 
I am okay with barell distorition on the wide. But vignetting is something I want to totally avoid. 
All you experienced folks out there, please guide me. Would also appreciate any links to lists that enumerate the same. 
Alternatively I am also open to using prime lenses, but they are really low on my preference. 
Appreciate your time and response. 

In most software that allows you to add in some vignetting, you can also subtract it.  
Some apps have lens profiles so they know how much vignetting occurs with that specific lens and at various focal lengths.
But you can also do this manually.  In astro imaging we calls these images "flats".  The purpose of a "flat" is to determine how much vignetting there is in an image so that we can correctly adjust for it using a program like Photoshop.  
To create a "flat" you would cover the lens with a piece of white translucent fabric.  Put some light on the fabric so that the fabric itself is evenly lit.  This means the view through the camera is basically just an all-white field with no contrast or features.   Then take a photo (it doesn't matter that the camera cannot focus on the fabric.)
What you'll get is an all-white image typically brighter in center and dimmer toward the edges but the image can be used to measure the lens' specific vignetting (and in the case of a zoom that level of vignetting would vary by focal length.)  The image can be used as a reference image with software to completely eliminate vignetting.
A photographer would normally not go to such extremes to get a perfectly flat field (lighting wise), but astro-imagers have to do this as a matter of routine.

  • HT201673 I would like to use cellular data for internet and my home network for printing, without having to cycle wireless on and off every time I print

    the only internet connection I have at my home is a cellular  connection. It is very unproductive having to turn wifi on to print and then back off to reconnect to cell service. Looking for options. I own a linksys e2500 router that I currently network through, but it has no internet connection, as no home internet available in my area.

    You can have a go using a wireless bridge.. eg the airport express will do this.. you can join it to the iphone wireless running as a hotspot.. and then plugged into the TC wan port.. the TC has to be setup in router mode.. so this is going to give you double NAT errors.. and of course errors for all the time the hotspot is turned off.. but it can work. However you might find it requires you to manually connect up each time.. If you are really going to try and do this you will manage it.. but how fiddly it becomes might put you off after a week.
    You will chew up your 5GB very fast using any streaming media even radio. So be very careful to track the usage.
    Apple should have built in the TC the ability to plug in a wireless 3G modem.. via the USB but Apple have ceased to do adventurous stuff.
    If you give up the TC as main router there are plenty of better products on the market that will handle multiple wan connections.. !!

  • My plugins (inserts) are showing a strike-through them and all get is a track without any effects on it. How do restore the remove the strike-through of the plugin?

    I completed a projected which I saved and closed. Afterward I reopened it to make some changes but found that all the plugins (inserts) in all the tracks had strike-through signs on them and when i tried to play the project all I got was sound without any effects. How can I fix this issue?

    That would indicate that the plugin or plugins in question.. are no longer available... for some reason..
    Did you change Logic's start up mode from 32 to 64 bit after you last saved that song? (and the plugins you were using were 32bit only versions)
    Have you checked the AU Plugin Manager to make sure those plugins are still available?
    Were the plugins used,  demo versions that have now expired or become disabled for whatever reason?

  • Can we zoom and use value pairs for the axis?

    Hi!
    I am utilizing visual C++ 6.0 and Component works for my current project where we are displaying some electrical faults on the CWGraph class in log scale. The X Axis is in duration format, i.e. ms, sec, min, day etc. and I am utilizing value pairs to properly display the labels values in the X axis. I set the major and minor unit interval values to zero and added value pairs for the X axis values 1 ms, 10ms, 100 ms ...1 day, etc. ( I looked at the answers to the previously posted questions for this!!). Hence I can show the values in log scale for the x axis succesfully. However, after adding the value paires, the two axis zoom option, track mode = ZoomrectXY doesnot work and I cannot zoom when I display the graph. If t
    he value pairs are removed and use normal scaling, the zooming comes back. Is there a workaround to this problem.
    I would greatly appreciate your help!!
    Asaf

    Bilal,
    Since I am using my custom x axis labels as value pairs, I need to check the auto-scaling false, otherwise the log values for the x axis and value pair labels mix and do not look good on the graph. Below are the settings I used for graph:
    Axes->X Axis->Scale Style->Auto Scale: Unchecked
    Axes->X Axis->Scale Style->Minimum : 0
    Axes->X Axis->Scale Style->Maximum : 1e+009
    Axes->X Axis->Scale Style->Log : Checked
    Axes->X Axis->Scale Style->Inverted : Unchecked
    Axes->Y Axis->Scale Style->Auto Scale: Checked
    Axes->Y Axis->Scale Style->Log : Unchecked
    Axes->Y Axis->Scale Style->Inverted : Checked
    Ticks->X Axis->Tick Spacing->Major : 0
    Ticks->X Axis->Tick Spacing->Minor : 0
    Ticks->X Axis->Tick Spacing->Base : 0 ( All grayed out)
    Ticks
    ->Y Axis->Tick Spacing : Automatic
    The other settings are assigned default values.
    Hence, as I mentioned before the X Axis values are assigned as 1 sec, 10 sec, 1min, 10 min, 1 h ..etc.
    and all on log scale. I need to utilize value pairs for this I think. Since I do not want the auto scale values, I uncheck it. You mentioned by unchecking auto scale, one will not be able to zoom. If so, is there another approach to display the graph as I want and zoom at the same time?
    Thanks,
    Asaf

  • I have created a newsletter in indesign cs4 how can I set zooms for each article for the user

    I have created a e-newsletter in Indesign. I have successfuly saved it as a SWF then as a PDF from acrobat.
    The problem is that when the user zooms in the resolution is not good.
    How can I let the user zoom in to read each article. Would I create buttons with zoom settings for each article. If this is the case do I do it in Indesign or Flash and can I still save it as a PDF file and it will keep the interactivity?
    I would greatly appreciate any help with this issue. It is driving me mad trying to get the information I need.
    Thank you

    Hi Bob
    Dont know what you mean by deleting my signature in the forum. Sorry its my
    first time using a forum.
    So just to confirm if I want a user to zoom in on an article I can't do it
    in Indesign or Flash.
    cheers

  • How do you set the zoom level to Inherit Zoom for all bookmarks in a pdf?

    How do you set the zoom level to Inherit Zoom for all bookmarks in a pdf?

    beatngu13
    I made an account just to "like" your comment and say that you are a god among men.
    I've been searching for hours about how to make the zoom level persistent throughout following links in various PDF's I have, and most sources were saying to just buy acrobat pro and edit the bookmarks manually with it.
    I saw that it was possible to write an application to change the property, and considered doing it after the only pre-existing custom application I could find was asking for $50.
    Thanks to you, I no longer have to worry about re-zooming every time I click a bookmark, and I'm not out $50 or the time it would take to code an app myself!
    From the bottom of my heart, thank you!

  • Any chance someone could make a Safari Extension similar to Facebook Photo Zoom for eBay?

    Any chance someone could make a Safari Extension similar to Facebook Photo Zoom for eBay?
    >> It would be a great help while browsing, Thanks!

    It's not the router.
    I have several pre-Intel Macs with 10.4.11 and most were fairly fast machines in their day. We also have 50MBps cable internet. All our G-series Macs are "dial-up sluggish" with anything on the web regardless of browser, yet running a download speed test shows they a connecting at a fast rate.
    Watch the browser status bar during page loads--I think there is a clue there. All the bacjground ad sharing and tracking stuff---google analytics is a heavy hitter--are apparently not optimized for the G-series and much of what you are waiting on is that type of third-party dreck phoning home. You can't fix it--web developers embed this stuff. Money, ya know!
    The browser TenFour Fox tend to stall less than Safari or FireFox on the older Macs. It somehow tricks websites to seeing it as an Intel Mac version of FireFox. Still not blazing fast but a big improvment.

  • Zoom for 8520 Curve

    Hi,
    Seem to be having problems getting a zoom lenz for a 8520 Curve blackberry, the one with lenz on corner of phone.
    Is there such a product? - I have found an ebay item (6x Zoom Lenz and Tripod) but seller can not tell me if it will fit the CURVE version and it does not look like it will.
    Some info on a lenz zoom for this blackberry model would be cool!

    no takers?

  • My iPhone 5s text zooms for no reason ?

    My new 5s enlarges/zooms for no reason. It happens now and then, and I have to force it off - thats even hard sometimes as to get to swipe it to turn it off - but when I do get it off - then reboot, it goes back to normal size. Is this familiar to anyone else ?? any suggestions welcome, thanks.

    have you enabled the parallax efect? turn it off try that
    turn off by going to Settings → General → Accessibility → Reduce Motion → and turning ON the Reduce Motion switch.
    also there is a zoom option in accessibility disable it if enabled

  • How do I change the default zoom for New Tab only?

    The New Tab zoom in Firefox 33 is too high to see all 12 of my thumbnails. I changed it using ctrl- but the next time I opened a New Tab, the zoom was back at 100%. How do I change the default zoom for New Tab only?

  • Fill screen with zoom for small photo sizes (as in slideshow)?

    Front facing iPhone 4S camera sized photos are too small in iPhoto. Is it possible to set a default to fill screen with zoom for all photo sizes (as in slideshow)? Seems like the old iPhoto worked like this.

    That's what I was afraid of!  I wish it would still scale photos to fill the window also if they're smaller  than the window size (not just 100%), like it used to in older versions of iPhoto. Especially irritating, since the problem photos are from an Apple product, the front facing camera of the iPhone4s.  I already added my complaint to "feedback".
    Thanks anyway.

  • Which telephoto lens for the 70D

    I have a Canon 70D and am interested in a telephoto lens for it. I own an EF18-135 IS, an EF 55-250 IS USM and recently purchased a new EF 70-200 F4 L USM (non IS, that was a mistake). I am thinking about getting the new EF 100-400 L IS II USM but I'm not sure if, for the money, it may be smarter to get the EF 70-200 F2.8 L IS USM and put a 2X extender on it thinking that way I can take the extender off and have a top of the line 70-200. I realize it would be F5.6 at 400mm but so would the new 100-400 and it will never be an F2.8. Any thoughts on the subject would be appreciated, just remember I'm a newbie. Thanks

    I wouldn't recommend anyone buy the old 100-400 at anything close to the regular list price until we know a lot more about the new version AFTER it's been in use by the general population. That said I'll add that it took me a long time to adjust to using a push / pull zoom but once I did I can easily say that helps me get better results. By using it vs a twist to zoom lens my hand is at the front of the lens right where the hood mounts giving me a more stable hold (support) than if that hand was near the back of it. The new lens will be even heavier so you'll need to find a way to hold it, twist it & control it's weight.
    Because I shoot fast paced action at slower shutter speeds lens IQ isn't as important as my panning skills so I really find it hard to believe I'd see a noticeable improvement to what I shoot but many others probably will see a difference. I bought my 100-400 in late 06 or early 07 & it still delivers nice sharp images & is one of the 2 lenses I shoot a lot.
