Of course manual focus can be achieved on a known moving subject with a known path. Focus tracking deals with subjects that are unexpected, ones for which you by definition cannot pre-focus for.

I think we all know that. nospam is trying to narrow the argument to one he hopes he has a chance of winning. This has already been pointed out to him. It all started when Charles wrote: "SLR with mechanical shutter speed and aperature controls, along with ASA setting (ISO I believe is a newer term.) Match needle metering with option to switch from full screen or spot." .... and nospam replied: "you could have any camera at all and you'd choose one with 50 year old technology???" It never was just about focus tracking. I don't understand why everyone is arguing. Of course manual focus can be achieved on a known moving subject with a known path.

Of course manual focus can be achieved on a known moving subject with a known path. Focus tracking deals with subjects that are unexpected, ones for which you by definition cannot pre-focus for. If someone or something out of the blue comes racing towards you on an erratic path, getting that subject manually in focus is simply a matter of luck.

You hear a plane, you spin around, and you have a very short time to get the shot. It's difficult even with AF. Personally at air shows I don't listen for surprise targets, I acquire the target visually. Then any aircraft making a low pass is usually following a very predictable path, either from left to right, or right to left, right in front of me. With a manual focus camera, I could in days past, pan with the target as it made its pass. Fortunately, these days I am blessed with multi-AF points, 3D-Tracking, continuous AF, and a frame rate of 8 fps. With a fast, low pass I can capture 4 to 6 frames the majority of which would be in focus. https://db.tt/AJjo6VB0 https://db.tt/Lg43IZf9 -- Regards, Savageduck |

wrote: What started all this was you questioning Charles' preference for a camera which leaves all the choosing to the photographer. Charles' preferred camera would make no choices at all. all cameras can do that. just set it to fully manual. done. meanwhile, you get the benefits from a modern camera, including much more accurate shutter/aperture mechanisms, digital imaging, better ergonomics, lighter and smaller body, much better lenses (which won't work on the older bodies), just to name a few. anyway, let's see him track-focus a hockey game. Trying to narrow the argument, eh? nope. Yep. The discussion was not about just track-focusing. yes it was As you wrote (see above) it was about "trying to maintain focus on a moving object without autofocus." human reaction time is simply too slow to maintain focus on a moving subject. the example of pre-focusing to a particular spot proves that. you're not tracking the focus, you're *waiting* for the subject to appear at a known location. try photographing stunt planes, birds in flight, wildlife in their natural habitat, dancers on stage, all moving entirely unpredictably. while you *can* get *some* photos, you won't get anywhere near as many keepers if you let the camera handle the focus. also keep in mind back then, most photographers prefocused in an area and then took a photo when the subject was in that spot. that's not track-focusing. Which is why you don't absolutely have to have track focusing. nobody said you had to have track focus in all situations. for instance, still life photography does not need it. Charles was not crippling his camera by leaving out autofocus. like hell he wasn't. there's a whole world of opportunities not possible without it. |

In article , Tony Cooper
wrote: The more important point is that photographers were able to accomplish things like in-focus shots of rapidly moving objects before autofocus. actually they weren't. Photographers were not able to photograph rapidly moving objects before autofocus? they can't. human reaction time is too slow, which is why they had to resort to techniques such as pre-focus of a specific spot. I grew up in Indianapolis, and attended the Indianapolis 500 mile race many times in the 1950s. Photographers were photographing race cars speeding around the track then. Horse races were photographed then. Track meets were photographed. All kinds of sports photos were taken. situations such as race cars and track meets are on a constrained track where movement can be accurately predicted. try wildlife, birds in flight, stunt planes, dancers on stage, etc., where you don't know what the subject is going to do next. good luck. you might get a few shots but it's a lot harder and you'll miss more than if you had the camera focusing for you. what they were able to do was wait for the subject to be in a particular spot and then take a photo, hoping it will be a good one. Sure...we do that today. Most of my better baseball shots are because I anticipated where the action would be. When I get the ball in the photo when the catcher snags a pop-up or when the ball is just in front of the mitt of the first baseman on a put-out, it isn't because I track the ball. Anticipating the action is what any good sports action photographer does. They don't track. You might follow an eligible receiver in football and hope to get that shot of him catching the ball, but you don't track the ball. You can follow the player with manual focus. bull**** you can. human reaction time is too slow to follow it unless they're moving relatively slowly or laterally where the distance isn't changing much. but hey you know better. nikon and canon should have called you before wasting huge amounts of money developing highly sophisticated autofocus systems that can identify and track moving objects and professional sports photographers should also have called you before wasting their money buying those cameras when manual focus would have sufficed. If you want a photograph of a slide into home plate, you don't track the runner from third. You anticipate by focusing on the catcher before ball is pitched if there's a runner on third. what if something happens elsewhere on the ball field? don't you see how limiting manual focus is? if something happened at a different spot, then they were out of luck. We still are. You don't track a football, baseball, tennis ball or hockey puck. You prepare the shot in anticipation of where the object will be. Sometimes it doesn't work out right. you can't always know where the subject will be. taking photos of rapidly moving subjects with tracking focus is very different and something that was not possible back then. Sometimes I wonder if you ever really photograph anything. You obviously don't understand how action photos are taken if you think tracking is the only way it's possible to get a good photo that involves a rapidly moving person or object. it's not the only way, but it's the most effective way. but again, you know better. go tell nikon and canon, who have developed incredibly capable autofocus systems, that it's not needed. It's easier today to get the ball or the race car in the picture, but it's ignorant to say that photographers weren't able to before autofocus. it's not ignorant at all. it's a limitation of human physiology. human reaction time is too slow to track focus of a moving object. a modern autofocus system can do *much* better than any human ever could. what you're describing is predicting where something will be and pre-focusing. that's very different. |

Particularly when the "photographer" doesn't have to worry about being skillful because of the budget. nonsense. of course they do. Hell, just set the damn thing in video mode @ 60 fps and, like the monkeys, you are bound to find ONE good shot among the thirty thousand or so frames you have captured, eh?!? that won't work for several reasons. |

wrote: Mr Cooper correctly points out the "romance" of using what nospam calls a "50 year old relic", but I respectfully would point out another advantage of the 50 year old relic: it STILL works. so what? modern camera still work. nobody is going to try to use a camera that's broken. that's one of the dumbest reasons *ever*. Every year, Nikon, Canon, and others come up with the latest whizz-bang grand slam super fantastic camera that is supposed to be better than anything from last month. and it generally is better, sometimes by a little and sometimes by a lot. it's called progress. My Canon FX was the flagship camera for Canon from 1964-66, and manufacture continued into 1969 (based on date codes). A five year run of an essentially unchanged camera design- let's see that in this wonderful digital age. (The placement of the serial number was changed in 1968.) that's because there wasn't much innovation back then. why would anyone want to stagnate for 5 years?? technology moves at a very rapid pace and people like you want to squelch it. As for the 'image sensor' in my camera, a very critical part of the imaging chain, it has been updated frequently since 1964- every time the film manufacturers introduce a new film, I get an updated image sensor. and one that is nowhere near as good digital sensors. you're living in the past. |
