IS off or on?

Another which is better.  Look at these.

_DX_1435.jpg_DX_1437.jpg

 

Now a 200% crop of each.

Both shots are made with the Canon EF 300mm f/4L IS USM Lens.  One shot has the IS on and a UV filter.  The other has no filter and IS turned off.  Worse case to best case? No right or wrong just a curious example.

A lot less stuff for 2018 but still a lot of Canon stuff. Along with, a lot of other stuff.

Re: IS off or on?

Without knowing the exposure settings, this is an exercise in futility.

Actually, we learned our lesson from your previous demonstration. I just wanted to point that out to you.

 

It has also been pointed out to you several times that some combinations of camera and lens have the smarts to automatically disable IS when the combo senses that it is mounted on a tripod. Despite posting a link to the Canon article, you still refuse to accept that behavior as fact.

On that note, I wish to offer my congratulations. You have demonstrated that there is no difference, probably because the gear you used has the smarts to automatically disable IS.

Well wrong again as usual my friend.  The IS was working just fine.  Admit the fact you can not tell the difference as is most always the result when believing in all you read instead of actual hands on testing.  Some do, some watch!

 

Again let me ask humbly, "You know the "ignore" feature is a often missed and little used feature of this board.  Why don't you try it?"


I suggest that you practice what you preach.

 

[EDIT] BTW, you proved my point. You think the IS is active, when it is not.

You are right, my friend.  When I don't respond to your, let's say, less than accurate replies it is because I didn't see them. Ignoring you by me accomplished the same end. 

Bye!

I thought the second picture was a little sharper. Am I the only one who sees a difference?

I don't see the originals of two of Ernie's posts that Waddizzle quoted. Did the moderator give them the hook or something?

I did not see a difference, nor did i look for one.  The 5 MB file size limit degrades the images to the point of “why bother.” Besides, one shot used IS and a UV filter, and one shot used neither IS nor UV filter.

So, if you perceive a difference in the images, then what would you say caused the differences?  IS or UV?  Not enough info, IMHO.  Never mind the fact that the file size limit degrades the images to the point that any critical comparison becomes moot.

Robert,

"I don't see the originals of two of Ernie's posts that Waddizzle quoted"

 

I put the him in the 'ignore catagory' so perhaps that is why they don't show up.  If he ever offered anything constructive I would like to converse with him.  But he doesn't.  One of us has to tke the high road.

Robert,

I did not intend for this to be the defacto practice.  It is merely to show that the IS on or off, the filter or no, is not a game changer like some want you to believe.

Is there any difference, of course there is, but how much is the question.

 

I have taken literally thousands of pictures since I retired and have come to some interesting conclusions.  One thing I have found for certain is , you probably don't know all you think you do.  And, if all you do is sit behind the keyboard you never will learn.

A lot less stuff for 2018 but still a lot of Canon stuff. Along with, a lot of other stuff.
