a question for Camera reviewers... ??
May 5, 2019 07:49:15 #
Why do the folks who write "camera" reviews, never use the same lens?
What I mean is, they "want" to be fair, but put a Nikon with a Nikkor 18-55 lens up against a Canon with a Canon 18-55 lens?
If you are reviewing the "cameras" why would you not get; say- 2 each Sigma 50 mm, one to fit Nikon, and one to fit Canon, and then review the cameras?
It seems to me, that mixing the lenses, (Nikkor, and Canon) in with the cameras... would muddy the water.
while they are the same size, 18-55, they're not the same lens, and they will perform differently, as well as the cameras...
if this has been discussed, sorry...

I am not an expert but if I own a Canon camera I want to know how it performs with Canon lenses. Same with other brands. Your logic is sound to me on a scientific basis but perhaps the 2 Sigma lenses might even have variations or might work better with one brand camera over the other due to software differences.
Good question and perhaps the scientists here can answer why.

Not long ago Canon lenses were not compatible with Nikon cameras and vise versa. Some things MAY be different today. Besides, are they reviewing a camera or testing a lense?

What manner of magic do you propose to put the Nikon F-mount lens onto then EOS EF-S mount?
Assuming you've found an 'internet expert' that is presenting a comparison of Nikon DX 18-55 to Canon EF-S 18-55 results, it would be relevant to the discussion that they're comparing sensors of the same size, say both 24MP and consistent camera settings via SOOC JPEG. I would expect the differences to be subtle to non existent in the images, with price and ergonomics being the points of comparative difference.
But then again, it's rare to find a qualified 'expert' to be comparing cameras of different brands, given the multitude of variables. Typically, they'll assess the camera independently or to the prior model of the same series. Is this an imagined issue on your part, or can you link us to an example?

The reviewer can review just one camera and give you opinion about it. He/she doesn't need to review any others. So If he review a Nikon with the Sigma lens he doesn't do Nikon justice because Nikon never intend to design their camera to be used with Sigma lens.
Besides the Sigma lens in EF mount and F mount might not perform equally. Especially AF.

I wouldn't put much worth into an 'expert' who misnames one of the two cameras being compared twice in the first 0:60 of the video ... You can find anything on the internet that supports your point of view, particularity a prejudiced view like this knucklehead .... He is trying to compare features and usability characteristics, where this is a difficult task as the cameras weren't built to a common set of requirements where you might objectively consider who did 'x' requirement better. I stopped listening when he started assessing the motives and brand strategies of the two companies ... He should just go back to his grandma's basement.

just laughing...
of course you are right.... and the really right part about reviews, very often, "a prejudiced view"...
I guess maybe I am bored this morning... time to pack up and go shoot some photos...
maybe I will get a few more opinions...
later for now..

I think that the same argument can be made for reviewing lenses. Specs and features listed side by side are more relevant than actual photos taken. Then there are the more subjective matters like user friendly menus, handling, convenience features like where buttons and switches are located, stuff like that.

These F-Mount to EOS EF-S mount adapaters have been around a while. The newer ones even have focus confirmation.

This is an excellent answer. My preference is to use Canon lenses on Canon Cameras and the same with Nikon. I don't use third party lenses, so when I read a review, I want to know how the camera performs with Canon lenses, not sigma or Tamron, etc.

Amen: I'm too old to worry about such things. My rule is: If it works well I choose it and if NOT , I Loose IT. So many things can go wrong when you mix blended manufactured items together to save a buck and wind up doing the opposite.
