dolina Offline Upload & Sell: Off p.1 #1 · 1D Mark IV in a Polo Game EXIF First time to own a 1-series body and first time to shoot sports with it. I was expecting more in focus keepers among the 160 shtos I made. I guess I either need to reread the manual or use the camera more. Feb 07, 2010 at 11:46 AM

Fish On Offline Upload & Sell: On p.1 #2 · 1D Mark IV in a Polo Game Very nice colors and sharp but why so slow of a shutter speed. You can see some motion blur from the mallet of the player on the left. Feb 07, 2010 at 03:43 PM

wyofizz Offline Upload & Sell: Off p.1 #3 · 1D Mark IV in a Polo Game Are the horses bred to be that skinny/thin? Feb 07, 2010 at 06:22 PM

dolina Offline Upload & Sell: Off p.1 #4 · 1D Mark IV in a Polo Game I was on Av (Aperture Priority) & AutoISO. EXIF I am unsure if the horses bred that way. The Philippines is a tropical country so too much animal fat may be a bad thing? Feb 08, 2010 at 03:24 AM

James Broome Offline Upload & Sell: Off p.1 #5 · 1D Mark IV in a Polo Game Nice work, but I too am confused with the selection of shutter speed/ISO. The motion blur *sometimes* helps photographs convey a sense of motion, but for something like this, I think the motion is inherent in the subject matter and doesn't need to be visible. To each his own, though. I probably would have moved up to 400 ISO so as to allow for a faster shutter speed. Feb 08, 2010 at 04:41 AM

Tom D Offline Upload & Sell: On p.1 #6 · 1D Mark IV in a Polo Game The statement you're making in your first post and the blurred horse legs in your second post lead me to believe that you're mistaking (unwanted) motion blur for an out-of-focus situation. I'm sure someone here will tell me I'm wrong, but 'Auto ISO' doesn't sound like too good of a thing, unless the shooting conditions call for it. I'm a little surprised, as the equipment lineup you have in your profile would normally tell us that you're already aware of how ISO affects your shutter speed. Not to mention, you're shooting with a giant focal length. Take it out of Auto and manually pump that ISO up until you get a shutter speed that freezes the action (if that's what you're really looking for), and you'll have more 'in focus keepers'. My apologies if you already got this figured out... Feb 08, 2010 at 05:10 AM

Rags Hef Offline Upload & Sell: On p.1 #7 · 1D Mark IV in a Polo Game I think #1 is spot on. The mallet may be blur because of dof. #2 SS is too slow, to stop the hooves you need at least SS1000 The horses are a special breed, called polo ponies. They're smallish and can stop/turn on a dime. They are aggressive and push other ponies/riders off the ball. here The games are real fun to watch. I use SS priority, auto iso, look at the link & you be the judge to see if I'm doing it right Rags Feb 08, 2010 at 05:21 AM

My apologies if you already got this figured out... lol sorry for the confusion but the photos I posted above do not have AF problems. I was referring to the photos I have deleted. I'll try to post some problem shots with the AF points highlighted in DPP. Auto ISO is a new thing to me as the 40D & 5D Mark II implementation were not as good as those of the 7D & 1D Mark IV. Actually the implementation of the 40D & 5D Mark II are "OK" but I didn't bother learning about exposure compensation with Auto ISO under Av. I was hoping for the very obvious and very helpful application of Auto ISO in Manual Mode. But I feel that the Auto ISO implementation of Canon is still imperfect when it comes to Manual+Auto ISO. I say this as as I can specify shutter, aperture, exposure meter but NOT exposure compensation. Feb 08, 2010 at 07:06 AM

Tom D Offline Upload & Sell: On p.1 #9 · 1D Mark IV in a Polo Game Sorry for the confusion, dolina. I concluded from your second shot that the oof hooves might be what you were talking about. So, I'm now concluding that your motion blur was intentional... like I said, while it seemed logical to me (based on the aspects of your post) that you might be mistaking the problem, it made absolutely no sense in light of the sweet equipment stash that you own. I'm envious. Looks like I need to read about auto-ISO, since I can't wrap my head around the advantage of giving up control of that to the camera. I'm sure it'll be an 'ah-hah' moment...

dolina Offline Upload & Sell: Off p.1 #10 · 1D Mark IV in a Polo Game EXIF EXIF Tom, I know where you are coming from not wanting to relinquish control to the body. Given that we are spending thousands of dollars for higher-end gear to make our life easier it would make sense to fully utilize what we have paid for. In the past I used to preselect the aperture/shutter and ISO then let the camera decide on the shutter/aperture. But now you can preselect the aperture and shutter then let the camera decide how sensitive the sensor will be. Now that I understand and can relate the metering modes to the frame I am shooting and how much compensation that is ideal to a scene I then became more confident with Auto ISO. Nikon has had it for a long time and to my knowledge they implemented it better. Canon is laggard in this regard. Feb 08, 2010 at 04:04 PM

Rags Hef Offline Upload & Sell: On p.1 #11 · 1D Mark IV in a Polo Game I have nikon stuff. I find it difficult to set iso when you're in the middle of the field and you point into the sun & in front of the sun, as your subject moves past you. Even exposure is tough. I don't mind giving the cam control when it's impossible for me to do it & get the shot Rags Feb 08, 2010 at 08:38 PM

Tom D Offline Upload & Sell: On p.1 #12 · 1D Mark IV in a Polo Game Okay, T think I'm getting it, Paolo. Still, it's not making sense to me that you would use in either Av or Tv mode, as it would leave two variables for the camera to decide on. How would it know what you're looking for in the situation where, for instance, you're in Av mode, want a shallow DOF, but also need to freeze the action with an adequate shutter speed? Seems as though your results would be all over the map-- a slow shutter and low ISO on one shot, and the opposite on another (all giving you the same exposure), unless there is some other kind of input you can dial in to narrow that down. Auto ISO seems to only make sense if you're in manual. Or am I wrong? Thanks for the clarifications, and I think we're gonna get shut down soon for this topic Btw, nice shots you're posting-- the detail is awesome on that Mk4... and Rags, I agree-- that radical swing in exposure is a pain when it forces you to make big changes to your ISO in a hurry (then back again)...

Oh the Tv/Av plus AutoISO didn't make sense to me either that's why I never used it on the 40D and 5D2. But I tried it recently and it appears the body has a limit how slow the shutter speed will be before lowering it any further. It would first increase the ISO sensitivity and if it hits a wall slows down the shutter. Like if I had a 40D with a 24mm lens set at f/1.4 in a dark room. The 40D will hit ISO 800 then start slowing down the shutter to 1/25. If it isn't lit enough it slows it down further to "0.3 or longer. Same thing with the 5D2 it would hit ISO 3200 then slow down until 1/25 and if it isnt lit enough to something slower. As for minimum/maximum shutter speed I believe there is a safety limit within the Custom Functions of your body that allows this. If you want to pre-set the shutter in Av you go Manual + AutoISO. My problem with AutoISO under Manual mode is that the 5D2 and 40D are set to ISO 400 for AutoISO. It honestly makes no sense to me that they pre set the AutoISO to 400. Shouldn't it be from 100-800 or 100-3200? In the 7D and 1D4 it has a more proper implementation but unfortunately it has no exposure compensation so if you decide to have a bias of -1/3 or 1/3 you cannot do this with the current bodies. Maybe the 550D has the proper implementation. If Canon's smart they would implement exposure compensation in AutoISO under Manual in the next firmware.I like pre selecting the shutter & aperture whenever I shoot and would prefer the camera to adjust for me the ISO based on my preferred metering mode and exposure compensation bias. For the polo game I was located at the south goal post. The sun was located at the south west point. Sweet light, sweet light indeed from 411pm to 505pm Feb 09, 2010 at 02:47 AM

ishootsports3 Offline Upload & Sell: Off p.1 #15 · 1D Mark IV in a Polo Game I think they look solid, i agree with what has been said about SS and that more iso would not hurt at all considering what that body seems capable of(my d3 lives in the 800-3200 range) but i have to say, why would anyone play polo on a horse? i mean bike polo clearly is the better form of the game Feb 10, 2010 at 06:52 PM

jcmedeiros Offline Upload & Sell: On p.1 #16 · 1D Mark IV in a Polo Game I think instead of Auto ISO I would use CF I 8-3 (Safety shift ISO) when shooting TV/AV. It has never let me down with the Mk III when shooting field sports that require stop action and I expect the same from my Mk IV. Feb 11, 2010 at 12:56 AM

Polo ponies aren't 'ponies' in the usual sense of the word; they're full sized horses. They're a 'type' rather than a 'breed'. In the US, the better ones are often crosses between Thoroughbreds and Quarter Horses. They need to be extremely fast and agile to be competetitive. They''ll beat any car in acceleration from zero to 40 MPH. Nothing wrong with the physiques of the horses in the pictures - they're very fit and healthy guys. Paulo, Nice shots. I find polo a real challenge to shoot. I've only shot a few games and I got a lot less keepers than I do with football or hockey. The play is very fast! There's no polo in my area until the spring, but I'll definitely try again - It's a fun sport to watch, and a great place to work on improving my skills in tracking fast action. I don't find a bit of motion blur all that objectionable, so long as the horse's head and the player's face are sharp. That said, I usually try 1/800 or shorter. At 1/800, I often get some motion blur on the end of the player's mallet, and on the horses hooves. I find I need to go to 1/1600 to freeze the action as much as I want. Al Feb 12, 2010 at 10:19 AM
