Tracking with SL2 and suggestions to shoot Karate games.
« on: March 14, 2018, 11:55:41 PM »
Hi,
I am going to shoot some pics during karate games for friend. I did took some pictures before in similar circumstances once with 70d and 80d.  I used Tv mode with auto ISO using 70D. I think, I used M mode with auto ISO using 80D. I can stop down lens by 1/3 stop with M mode instead of wide open ( as in TV mode) which helps with IQ. 

My best pics are  with 70d and Canon 85mm. Unfortunately, I do not have 85mm anymore.  I have SL2 now. My existing lens are Canon 50mm, Sigma 17-50mm and 105mm. I used Servo mode with Auto all focus points.  with SL2, I might not be able to use similar AF modes. Any suggestions to shoot moving subjects with SL2 and how to cope with just 9 AF points.  I can shoot in M mode using EC with auto ISO. That will help me to adjust exposure with white back ground. My both Sigma lens are calibrated with SL2. Hopefully, there wont be any focusing issues.

I use live view with my SL2 whenever I can.  Lots and lots of AF points and tracking is good, but not great.  Lack of light can be a issue with a crop camera.

Maybe I am wrong because I do not know karate sports exactly: I think you have very fast situations and some motionless situations while both "fighters" are going through the next steps. Her two ideas:

ADD: Just seen that Mt. Spokane made a similar proposal:
Do you have tried DPAF with tracking for your purpose? In Macro photography it is a true gem when a plant is shaking in the wind. If DPAF with tracking is predictive (I think it is) it can do the math to extrapolate the motion of the subject in focus until the shutter is activated. And shaking plants in macro at f/5.6 are a true challenge because of the very thin DOF.

Manual pre-focus could be an option if you can extrapolate where the actors are when you want the shot. The screen of the SL2 is very good for manual focusing (for a screen without microprism or split image indicator) - if you have contrasty subjects and enough light. But I had 20 years of MF experience before I bought my first AF camera in 2005, so maybe a lot of neurons in my brain are trained good enough.
Most used tools: EOS 200D + EF-S 60mm + 4.0 / 70-200 IS AND/OR EOS 5D i  + 4.0 70-200 IS + 2.8 100 Macro

Thanks for the information. I never used servo tracking with live view. I will check the manual for settings. I might need to buy backup battery a well. There will be a good light for the eye. But fast shutter speeds is going to be a problem with crop.  With fast shutter speed (1/800) and f/2, iso's are around 3200. I no longer have 85mm. I end up using Sigma 105mm f2.8 lens.  With live view, light is going to be a problem.

I can buy one back up battery for SL2 and try Live view tracking. It is going to be very casual photography with kids participating. I just need to get some photos during action and award presentations.
If I am going to use VF, Is it good idea to just use center point and fallow players. With 105mm, I can fill in players inside the frame.  With all points auto servo mode, not sure if SL2 can handle like 70d/80d who has lot of AF points. I have nifty fifly (older one without stm), which is also slow focusing.

Which 50mm do you have?  1.8, 1.4?  I would be tempted to say to use that, and if you are a little further away, just crop later.  But the light advantage will give you shorter shutter speeds which may be crucial in fast moving action.  (If you are really far away from the action, then the 50 won't work obviously.)

Unless they use spot lights, I would assume that lighting will be very even and you could probably get away with just using M mode.  Take some test shots, and when you are happy with the exposure, leave it there.  I would use the highest ISO you are willing to use with the SL2.  Probably around 1600 or 3200.  Then go from there with the lens wide open or one stop down if you want to bump the lens' performance.

Now you just have to worry about AF.  I'm not that familiar with the SL2 and I see others made good recommendations, so I'll leave it at that.

Live view does not affect the light situation, its the lens and the camera body.  It cost less to upgrade cameras than to get a expensive ultra fast lens.  The SL2 can do ISO 3200 pretty well, but DR can be a issue, you need accurate exposure.  With a FF body, ISO 3200 is a breeze.

I have old nifty fifty (f1.8 ) with plastic mount. I think, its AF is worse than Sigma. My options are using Sigma 17-50mm and 105mm. Sigma 17-50mm is pretty good wide open at 50mm. I can use them both wide open (50mm and 105mm). I will be very close to action. 50mm is enough with crop and I can use 17mm for taking presentation pictures. I got them calibrated from Sigma recently. I am also checking for used Canon 85mm 1.8.

I will be using veryr high iso (3200 or 6400) in order to use high SS. How does view finder shooting compare with live view. Not sure if i can select AF point other than center point. Or I can just use all 9 AF points with Servo tracking and see how it works. I need to look for used 6D to upgrade camera and need lens like 24-105mm and 85mm prime. I will planning to play around with SL2 little bit over weekend and see how it goes.

Not owning one, what does Sport method utilize? Is it Servo tracking and Program Mode in Jpeg?

Hi Ritholtz.
I don’t know the 6D but looking at the specs it only has 11 af points, and no dual pixel live view, it looks a lot like out of the frying pan and into the fire!
As for the rest of the camera I’m sure it is a vast improvement over the SL2.

Cheers, Graham.

6d will help me with high ISO.  Not sure about tracking improvement over 6d2. You are right about sl2 live view tracking capabilities. I checked DPR review. They also mentioned about using live view tracking using live+face tracking option instead of view finder tracking. But in my little experience with  SL2, view finder shooting is instantaneous and quick over live view.

I guess sport mode push up shutter speeds compared to normal auto mode. SL2 has auto iso in M mode. I can use M mode and have control over shutter, aperture and EC.

DPR suggested to use live view during servo tracking. Then what is the point of buying DSLR. Servo tracking suppose to be strengths of DSLR. If we are going to use live view with DSLR, I should be buying one of M.

Hi ritholtz.
To be fair you ask how to use the gear you have to the best effect, you get a suggestion and query it, would it have been more relevant to suggest you get a 7DII or 1DxII instead? No as that won’t help you track with an SL2 whereas using live view might!
