Lenses / Re: how to get 300 2.8

I understand your points.

Besides me, there are few more of us out there call it as "compression". (@ 6:03 to 6:05)

And that makes it correct? I don't see the smug satisfaction in refusing education and reveling in repeating inaccurate statements from self taught YouTube experts. But hey, have at it.........

I appreciated your attempt to correct my word. If you and the world both understand the term compression in photography, then why are we having this discussion?

Sorry OP for Hijacking your thread..........I'm done.

Because "Lens compression is a bullshit term used by people who don't know what they are talking about to describe a phenomena that visual artists have well understood for hundreds of years and is universally called perspective."

Just like so many memes, if it isn't corrected by anybody then the true learners can't learn. Understanding and controlling perspective is unutterably more important than thinking focal length changes anything, besides, you even introduced dof into the confusion that has become "lens compression".

I am not being elitist or pedantic here, I am just pointing out a commonly (and increasingly so) held misconception, I even posted two illustrative images to demonstrate how wrong the saying is.

Again, if you want to wallow in your own ignorance then have at it, but don't think you are doing those trying to learn any justice.

The human eye cannot tell the difference above about 24 fps, so a refresh threshold of about 42 ms is enough.
Not quite.  Cinema film shot at 24fps appears fluid to the human eye because it's projected at 48fps with each image shown twice -- as distinct from 48fps like Peter Jackson uses with a full 48 images.  If it was actually run at 24fps, you'd have a splitting headache.  Some projectors run at 72 images per second.

Carry on.

Regardless, your ability to see flicker isn't really related to your ability to track high speed subjects in the presence of lag.
No argument.  The effectiveness of a display is affected by refresh rate, input lag, and change response time.  The last is where an OLED EFV would have no issues.  The first two can cause problems.  The likely issue with any EFV would be input lag, if it's not sufficiently low.  Given that the data has to be encoded, moved, and redisplayed, the electronics would need to be very, very fast.

I pre-ordered a 7Dm2 several days ago, first one to order at our local camera store. It will be used with a Sigma 5-500 OS. The current 7D will then be used with a Canon 18-200 IS. My wife will continue to use her 70D with Canon 100-400 IS. In general, all the foregoing discussion doesn't reach to any features that will affect our bird photography. The higher frame rate is a compelling reason for me to upgrade. If other results equal or exceed my current 7D, all will be well.

EOS Bodies - For Stills / Re: Already bashing the 7d MkII because of the Samsung NXI?

The Samsung does 420MP/Sec.

The Samsung is also saving 12-bit files during continuous shooting vs. the full 14-bits in single shot mode.

So what?

You keep telling us that DR (and by extension 12bits vs 14bits) isn't important except to a small number of people so therefore this difference that you've highlighted is also relatively unimportant. Or do you wish to become one of your own DRones and insist that the extra bit-depth and thus DR is all of a sudden important?

As exciting as I was about the 7D MK II I'm probably going to pass on it for now as well as the 70D.
I rented a canon 1.4x III extender this weekend and I was amazed of the performance with my 5D MK III and 70-200 f/2.8 II. 
I'm still interested in something for video and use the glass I currently own. Time will tell what I choose. Thanks everyone for your suggestions.

+1 for the 16-35 f4. Picked one up when I went full frame. Really interested in the 15-30 hope it'll be a great astro lens :)

Hope you have some 3stop ND on hand for outdoor.

Back when I thought I had a deal done for an 85L we had a discussion about shooting the 85L in daylight and how you need a 3 stop nd... and I had one in my cart... for about 6 months until I had the lens in hand.  Then I ordered it. 

I bought a step down ring a while back because I got it for free, so I picked up a B&W 77mm 3 stop nd... so I can use it on my other lenses if I decide to...

Today when it was sunny I was still getting 1/2500 of a second, so without the nd filter, it would have been 1/20000... which I'm pretty sure exceeds factory specs. 

Tomorrow I'm taking my daughter's softball team photos... so I'm hoping for clouds, but I don't think that is going to happen until the games start...
