Canon vs. Nikon - Great You Tube Video

It's called focus breathing. Basically with some lenses, the closer you get to your subject it will give you less magnification. So a 200mm lens at close focusing distance might only give you a 150mm.
Here is a better explanation.

From what I understand, every zoom lens has a 'breathing' rating. These are hard to find for any specific lens. By breathing, it means simply that even though the lens is rated at say between 70-200 mm, it really only has a breathing zoom of up to 130 mm. Thus, the 200 mm lens is really only a 70 - 130 zoom lens. It doesn't probably help much, but that's pretty much the best for now of how to describe the effect.
I don't believe everything he had to say. He said only nikkor's af-s 50mm f/1.8 lens would AF on fx Nikon's and cost more than canon's 50mm lens. Is there a FX Nikon that doesn't have a built in focus motor to use the Nikkor AF 50mm f/1.8 d lens costing only about a $100 same as the Canon lens he was talking a about?
Not that any of this matters much to me. I'm not interested in switching brands! Lol

Very interesting comparison and balanced.
The thing that surprises me is that he is very critical of the Nikon 70-200 mm lens both version 1 and II.
I thought this lens was deemed to be one of the "holy trinity" of Nikon pro zoom lenses, it certainly carries a premium price tag ?
Do people that have this lens see the same issues i.e. significant breathing and loss of sharpness at the 200mm setting?

I did go through the Nikon-Canon Super telephoto comparison on DXO, and the Canon ones where marginally ahead from IQ point of view, but are way more expensive. That was before Nikon started using Fluorite elements to reduce the weight and enhance IQ.
All in all lenses from both the brands are near enough each other. If one is ahead today the other jumps ahead tomorrow, so in long term none is ahead. Where Nikon is scoring is in their High MP sensors - 24 and 36, while Canon is stuck to 22MP sensors. That gives the Nikon users some cropping opportunities the Canon users lack.

No Regrets with my VRII version. So what if I only get 130mm at 5 ft? At that close, I'm probably taking a portrait and 130mm is perfect. It's like the lens knows what I really need.

That's the way I see it too, Jim. If you need more than that, say for wildlife....then get a 400-500 mm lens. Not sure what the breathing effect would be on those, though....I'd be too busy looking in my wallet to give it any consideration!

That guy creeps me out for some reason.
Lol uh oh! Now you did it! Saying such bad words! You need to wash your mouth out with soap! Lol
He didn't mean it everybody! No need to get out the tar and feathers! He just has a moment of insanity, nothing serious! He'll be a alright again soon! It must have been the heat! Lol

I agree, he does come across a bit weird personality-wise.
Yeah I found him a bit odd first couple of times I saw him but stopped noticing after a while and thinks he makes some good videos. I was interested in his comments about Canon's 400mm 5.6 lens. If Nikon did have an equivalent that's what I'd be looking at. Currently weighing up a 300mm with 1.4X teleconverter.
Are you set on using a Prime or have you considered the AFS 80-400mm f/4.5 - f/5.6 ED VR
It gives you the f/5.6 @ 400mm and gets good reviews.
That's another one I'm considering. More recently I heard a few negative reviews of it, although some of the results I've seen on here are excellent. Either will be a long way off as I'm saving for a trip to Aus next year. A D7100 is likely to be my next major purchase, as this will be a step up in IQ and open up some cheaper non AF-S lenses as options. My aim is to have a set up which is capable of taking extremely sharp and clean wildlife images. I've spent a life time hunting so I know I can get close to critters, therefore 400mm should be plenty of reach.
