My terrible Canon 50mm/EF1.4 first experiense

Confused at why one would be shooting at TV? Try AV.

For fast action?

I highly recommend "understanding exposure" by Bryan Peterson if you believe that Tv is the way to get the highest shutter speeds...

Learn to shoot on MANUAL MODE

It's a question.

Also, why is Tv an included function in even professional cameras?

Let's be honest.

The more you write, the more I'm convinced someone just needs to step up and buy you a copy of understanding exposure, it's clear you don't get it...

For once Kanye has a point. TV is there for when you need a certain shutter speed in changing light and don't have time to adjust aperture in between shots.

I guess lots of people now rely on using auto ISO in M and specify the TV and AV.

What's the problem with using TV for fast action?

If you want the fastest possible shutter speed, you set your aperture to wide open and the maximum iso you find acceptable and you'll get the fastest possible shutter speed for the light. However, if instead you shoot in Tv and the light increases, the camera will stop your aperture down because of the increasing shutter speed and you'll be left with less than the maximum possible shutter speed. Tv is there for when you want a specific shutter speed, not the fastest shutter speed.

In AV mode, I can set the aperture on my zeiss lenses with the optix chipset, which automatically sets the shutter speed.

In TV mode, the aperture I click will set the shutter speed

The TV mode is substantially darker for manual lenses without programming the real aperture
My guess is that the TV mode sets a quicker shutter speed

When I shoot action, I don't want the shutter changing around on me, it's a guarantee that many shots will have blur. I will either shoot Tv with auto-ISO and EC pushed a bit to the right (or a specific ISO that will cause the aperture to go wide open if I care about that), or shoot in M to lock in both shutter and aperture, with auto-ISO. Av is the last mode I would select for things like basketball, hockey, etc.

I shoot at 1/1250 or 1/1600, at a high ISO like 6400. The aperture rarely goes over f4.

I agree. Tv for me has been for when I want a specific shutter speed for the right amount of blur for a type of shot, like 1/125 sec. when panning on something quick for example. If I want the fastest possible shutter-speed I use Av and set my min-shutter speed to it's max limit, which on the 6D is 1/250 sec. I think. M would be my second choice... but I rarely shoot anything that's moving fast.

So you're agreeing with me that you aren't shooting as fast as possible then? I'm not really sure what I'm not really sure what the take away from your post is suppose to be...

When do you need to shoot as fast as possible? What exactly are you shooting that you want as fast a shutter as possible? My point is that if you want to shoot at fast shutter speeds, you probably should know what limit you need, and work with that in Tv mode, otherwise you will have your ISO set higher than you really need and would be sacrificing ISO IQ. I am not really sure what you are saying. You said "why shoot Tv when shooting action, try Av". You gave no other parameters, and given what I shoot, that is the worst mode out of Tv, Av and M.

In any case, you may choose Av for that mode, but that is neither the best mode for all action shooting, nor are you going to convince everyone of that.

Has nothing to do with the lens...
