SX50 exif data
Mar 4, 2016 15:02:00 #
A question for the Canon SX50 experts:
I realize that the SX50 has the full frame DSLR equivalent focal lengths on the lens, but if I don't look at the point of shooting and am looking at the exif data after the fact, I'm looking at a focal length that represents what I believe to be the distance from lens to sensor. I've been told that the SX50 has a crop factor of 5.58. If so, am I correct in assuming that to get roughly the DSLR full frame equivalent that I would multiply the exif data focal length by 5.58?

Yes, but:
The math results in an equivalent angle of view as full frame, not focal length.

O.K. So the focal length equivalents marked on the lens are then indicative of ....? The selling point appears to be that the lens ranges from an equivalent of 24mm to 1200mm. I know I'm missing something here, but what?

you might want to rethink that statement.

Would you care to elaborate?

Linda was just reminding you/us that the crop factor is just a crop...thus ....angle of view modification.....or also known as digital zoom factor.
This does not negate the fact that the SX50 still has a optical zoom factor of 50 and that the optics in the lens are pretty damned good ! :XD:

Crop factor has to be one of the cruelest jokes on photographers by the manufacturers.
Everyone has to come to their own understanding of it.
Yes, multiply the actual focal length by the crop factor to get the focal length of the lens you would need with a 35mm full frame camera to get a similar view in the picture.

you may find this of use in getting from focal length to angle of view:

There are all kinds of technical stuff behind this crop factor business... For all practical purposes, you can regard them as focal length. I didn't know the crop factor of the SX50, but you are safe in regarding it as 'effective 1200'.
Heck of a lens, too! Mine has been relegated to '2nd-backup' status for quite a while, but I am trying to get used to it again prior to an upcoming trip back to the UK in May. No way I am lumping my other gear on and off all those planes...

Thanks. Linda's comments along with oldtigger's chart have helped to clarify the situation. Sometimes semantics in this wonderful field of endeavor really cloud rather than clarify important concepts.

Thank you. That is exactly the confirmation that I was hoping for.

Yes, it's currently my backup camera and will probably remain relegated to that position, but it has some very impressive capabilities. And in the hands of someone like LindafromMaine the results are outstanding.
