• astrophotography. I want to know that the focal length is to determine the field of vision?

  I'm interested in astrophotography.  I want to buy a camera for my telescope.  You can find the field of vision, if you know the focal length of the telescope.  But what is the focal length of a camera with a fixed lens?  If I have a 50 mm lens, is the focal distance 50 mm? or do you need to know the distance from the camera of body image sensor and add it to the lens focal length?  Thanks in advance...

  If you have a 50mm... lens focal length.  The focal length is the distance between the end of the lens and the image plane.  If you look at a digital SLR, there is a symbol on the body (usually the top of the body and often near the viewfinder) that looks like a small circle with a line through IT... which line marks the position of the focal plane inside the camera.

  There is a friction more... If you have a 'simple' goal, it would be the focal length.  Many modern lenses are technically able to be physically shorter than the focal length they provide... because of the types of 'glass' and the configuration of optics.  So the focal length is based on how long a simple goal should be to provide that same value (even if you were to physically measure it and not get this value.)

  All telescopes list their focal lengths, but also among the specs of the telescope focal reports.  I have a refractor of 540mm with an opening of 101mm... so it is 'roughly' f/5.4 scope.  I have also a larger 14 "SCT with a focal length of 3556mm and it is a stretch of f/10.

  The distance "flange to focal plane" on a camera Canon is 44 mm... in the grand scheme of things with a telescope, it will not substantially change the focal length of the image.

  Depending on the scope, you can use either a "focal reducer" or a "barlow" to decrease or increase the focal length.

  One last thing... many designs of 'Newtonian' type telescope is problematic for astrophotography.  This is because most of the glasses and catadioptric telescopes are designed with the intention that a person would use a diagonal of 90º with their eyepiece.  "The diagonal has a tendency to add"roughly"2" to the overal of the focal path length.  If you are using a camera you take this "diagonal" and simply attach the camera for a shot "straight through".  So even if you have lost the focal length 2 ", created by the diagonal... the camera adds"roughly"the same amount of back in.

  BUT... When you use a Newtonian telescope of reflector design, the eyepiece is near the front and there is no "diagonal" in use.  This means that when you add a camera, focal length gets longer, it would be with an eyepiece.    Pull door-eyepiece tube has some development trips... but because the camera is the longest focal length, you end up having to run the focuser completely 'in' to shorten the length of the focal length to put the image in focus.  And that's where you are having problems... very often on a Newtonian telescope, you exceed the limit of traction of focuser (you can't shorten the development any more that you have) and the image was just starting to focus... but it's still pretty fuzzy.

  This problem not to poison all the reflectors of knighting... some can accommodate cameras and still come to focus.  You really check the specific scope.

• Bad focal length

  Why the metadata display my focal length of my Fujifilm X 20 7.5 mm whereas it should be 28mm

  Because it's the right focal length, the lens on the 2/3 X 20 is zoom 4 x 7.1 - 28, 4 mm, equivalent to 28-112 mm on a 35 mm format

  My X100T has a focal length of 23mm, equivalent to 35mm on a 35mm format

  What you see is the reported correct focal length, not the 35 mm equivalent.

• Is there a way to manually opening of entry and/or the focal length of the lens corrections profile?

  This feature would be very useful for those moments when we shoot with manual glass or use adapters manual or really all cases where metadata is missing or damaged. It is to the correct lens distortions at a specific focal length in the case of the zooms. And manually impute the aperture value would determine how much vignetting correction and chromatic aberration correction is required.

  
  

  Thank you!
  

  This facility is not as much as I know sorry.

• The lateset, 2015.5 edition, does not transfer data from the metadata, only the focal length objective. Disappointment when you want to know what that lens you used. (It allows to rename the files but after you create a second copy. "It's an improvement.)

• calculate the field of vision or the focal length of harvest

  Is there a way to do this or a plugin that someone knows?

  (If you have a shot at a 14mm but you crop to the center of it, it would be good to know what is equal to the equivalent focal length of culture)

  Set the Info Overlay to show the new cropped dimensions. In the case the simplest where the aspect ratio of the culture is the same original image, divide one side original by the culture to get the crop factor. If the original is from a full camera frame, the equivalent of 35 mm. long focal length times the crop factor. If the camera has a sensor that is less than 24 x 36 mm, the total of crop factor is crop factor of the camera times the factor of culture "in LR. So, if you have a Canon 7 d, which has a sensor 5184 x 3456 pixels and a factor of 1.6 harvest and crop you the image to 2592 x 1728, the crop factor resulting is 3.2 and your 14 mm lens. will take the field of VISION of a 44.8 mm lens. on a 35 mm camera.. If the harvest of LR has an aspect ratio different that the original, the equivalence is, of course, different for the height and width.

• [Beginner] How you view focal length of 35mm EQ. ?

  How yo view focal length in 35mm equivalent?

  I found a plugin which sorts the photos in eq. 35mm, but I'm looking for a medium/plug-in that displays focal length in eq. 35 mm in the info of the loop.

  Any other editor of PP I have used in the past were less than LR, but always had the ability to view the focal length in 35mm. I wonder why LR, a far superior tool, is lacking in this Department. Since I still have to learn photography and use the 2 systems of interchangeable lens camera with factors of different cultures and although two compact cameras, through my pictures with the focal length in mind really allows me to get a better understanding of the perspective.

  This plugin can do what you want, but read on:

  http://regex.info/blog/Lightroom-goodies/focal-length-sort

  More than 35 years ago, I bought my first 35 mm SLR film camera and a bunch of privileged (i.e. objectives to single focal length) lenses. I walked with three 3 boxes, each fitted with one (1) 'main' focal lens and a camera with three or more lens bag. Fortunately, the equipment of series Olympus OM I used was extremely, compact and light weight, even by today's standards.

  With ranges of today zoom lens you can cover most tire using only two lenses.

  To "learn the purpose" why not create a spreadsheet containing a list of focal lengths of 35mm (14mm, 16mm, 17mm, 24mm, 28mm, 35mm, etc.) and add a column for each camera with its equivalent focal length model.

  You can then create a group of collections of LR based on the length focus groups for purposes of comparison:

  1.x Crop camera 1 1.x Crop camera 35mm 2

  super wide 14-20mm

  width 21mm - 35 mm

  normal 36mm - 69 mm

  70-299mm telephoto

  Super Telephoto 300mm and more

  Add images from one camera at a time by using the sort column filter bar "Lens" and your impression dandy new handy focal distance calculator spreadsheet.

  It will give you a much better appreciation of what your current hardware can and cannot do. And despite what says Web Weaver, you will never be able to take a picture like that with a 50mm lens:

  

• Interpretation of focal lengths specified

  Are specified for the real EFS lenses focal focal lengths or have they been adjusted to be equivalent 35mm?  For example, if an EF lens with a range of specified the 18-55mm lens is mounted on an EOS 70 d which has a 22.5 x 15mm sensor, angle of somewhat wide to telephoto, or makes the angle range very wide barely more standard.

  I had assumed that the listed focal lengths are true, but then I noticed Cannon describing a marked 50mm as a 'standard' lens, which would be the case for 35mm film, but not for a 22mm sensor.

  (Sorry to ask such a basic question.  I'm new to DSLR).

  -Ehz

  The focal length of the lens are real focal lengths.  They are the same regardless of the EF or EF - S.  Put on a crop sensor will reduce the field of VISION.  The 18-55 on a 70 d will include so something like would make him a 24-70 on a 35mm camera (technically, it would be like 28-88).

• Script to focal length metadata function

• Missing EXIF focal length

  I'm having this problem in versions 3 and 4. I have a Canon 40 d and all my photos that I edit in LR (uncropped) lack the focal length in the EXIF data.

  This does not happen with Canon DPP. LR will be the focal length in library view, but when he converted to JPG format and then displayed in ZoomBrowser or whatever this piece of program data is missing.

  Windows 7 SP1 x 64, x 64 LR, "reduced data embded" is unchecked as well.

  I'm doing something wrong?

  I can see what you have noticed for a JPG exported from a CR2 from a 5 d Mk II. BUT:

  The focal length is present in the Exif tag, but Canon ZoomBrowser or DPP will not show it. Try using the Windows Photo Viewer and check the properties, you will see the focal length there (as in other programs like IrfanView, ExifTool, etc.). Same distance from the subject (what is no longer displayed in LR3.6 or 4.0) is included in the format of JPEG Exif.

• Qosmio F20: Bad sound using the MSN Messenger & video transmission

  Hi all

  I recently bought a laptop Qosmio F20, who is currently connected to the Internet via a router/modem WiFi Netgear (DG834v2).
  I tried to use MSN messenger v7.5 (7.5.0311 and 7.5.0324) with a webcam Creative NX () to make a video call.
  But the sound of the person I'm talking to is so distorted, it is impossible to have a conversation (I tried with several of my friends, who all have good sound on their end).
  However, if I have an audio only (no video) conversation, I have a perfect sound.
  Despite my best efforts (update drivers, reinstall messenger, windows firewall ok for messenger etc...) I've had no chance of finding the problem so far. If anyone has any suggestions I would be very grateful.

  Thanks in advance.
  François

  Hello

  You suggested that the sound working properly without the video connection.
  In my opinion, it happens because of the webcam. Maybe the software has a bad influence on the sound.
  This is not a product of Toshiba, and Toshiba is not responsible for any 3rd party device.
  I recommend you to check the site of the manufacture of cam. Maybe you will find the solution.

• Satellite L20-214 - isolate bad sectors on the HARD drive?

  Dear Sir

  My laptop fell off my table leading to serious hard drive problems. The hard drive now has some bad sectors that can be repaired with the chkdsk command. I managed to get my data on an external hard drive. Despite the bad sectors, I can reinstall it however from the recovery cd. Starting after that time consuming (1.5 hours) and after starting Windows I get the error messages from programs that cannot be started. It's the same thing after each reinstall. My guess is that the recovery disk writes data on the same spot every time both on bad sectors.

  I was wondering if theres a way to fix or even isolate bad sectors on the disk, so I can continue to use my laptop.

  Your help is very appreciated.

  Hello

  You can try HDD Regenerator 1.61 (HDD Regenerator is a unique program for regeneration of physically damaged hard disk drives. It does not hide bad sectors, it really restores them).
  However, the best way is to buy a new hard drive :)

• Satellite P10-304: bad sectors on the disk - how to fix?

  My drive HARD drive bad sectors developed and replacement needs, does anyone know how to do this?

  Hello

  I found these tips how to disable the Norto Go Back tool.
  You can uninstall it from your computer, disable GoBack to your laptop press 'space' GoBack screen button and select the option "disable" GoBack.

  Follow these steps:
  1. reboot your computer.
  2. when the Norton GoBack splash screen appears, press the SPACEBAR.
  3. in the Norton GoBack boot menu, click on disable.
  A message informs you that disable Norton GoBack erases history and you will not be able to run the hard drive or hard disk restore advanced restore until Norton GoBack is turned back on.
  4. click on Yes.
  5. click on continue.
  Your computer restarts automatically, and Norton GoBack is off
  After restarting the laptop, I recommend once again using the following key: CTRL + ALT + G.
  Immediately press on and hold the keys Ctrl + Alt + G after restarting the laptop you. A message you giving the possibility to force the removal of GoBack master boot record. Press F to force the removal of GoBack master boot record.

  If failure of keys Ctrl + Alt + G in the first time then try this again for three or four times until you get the prompt to remove the master boot record of GoBack.
  Finally, restart the computer.

  To fix bad sectors on the HARD drive, you could boot from the XP CD to use the console of "repair".
  And then use the CHKDSK /p command to repair the bad sectors.

  Good luck
