I didn’t like the crop factor explanation too much. Sorry! Needs more illustrations, I think.

BTW, I already know what crop factor is… but if I didn’t, I would feel this article is incomplete.

Ok,
I think my earlier question was little confusing.
Here is the simplified question –
“When I look through my view fider(eye peace) do I see the image that is full frame image(i.e. crop factor needs to be applied on it) or it will be the exact image that my DSLR sensor will imprint(i.e. a crop factor is already applied on it)” ?

I understand that crop factor will cut the corners.
Here is my question – when I see through the view finder, do I still see what the lense is seeing or do I see that the sensor is going to imprint ? and I believe these two are still difference as lenses focal length is never changed. right !
Now how do I make sure that I am not losing an object which is near the corner in my view finder having the knowledge that the sensor is going to cut some portion from the corner !!

I love your ability to get right to the point!

You assisted me in figuring out what crop factor means in 2 minutes and I have read several articles on crop factor in the past two years and frustration was the end resuls, I just could not get it!

I choose to learn something new about digital photography each day! Today was a great day!

Simplicity is always best!

Thank you… Thank you

So if I crop out one quarter…or less…of an overall image and enlarghe it to check sharpness, color, etc., have I come close to achieveing the same thing?

I agree with James Tibbel’s comment saying that we are making far to much about it. Amatures probably don’t care and professionals, especially those who migrated from film, already understand the concept although they never called it “crop factor”. When you put a 4×5 back on an 8×10 view camera, or a 120 back on a 4×5, you simply looked at the ground glass and recomposed your picture or changed lenses or both. The manufacturers don’t make things any easier for new photographers by hyping the pixel resolution and burying the actual sensor size.
