Why do you bring up the subject of shooting at 6 seconds for a full rotation with a 400mm lens?
If youÂ´re willing to look at it closely: i didnÂ´t relate it with a 400mm lens at all. That would be complete nonsense - you should know that.
No-one. Anywhere. Has suggested to do this.
Right - thatÂ´s why i didnÂ´t relate to it anywhere.
Why - for the third time - are you trying to imply that speed modes (regardless of which head is being talked about) are of no use because of the fact that at their fastest setting they're not suitable for use with long lenses? It's as ridiculous an argument as saying that there's no point in having a car that can go faster than 3 miles an hour because that's the fastest speed you can use when parallel parking it.
It is nothing short of willful and deliberate obfuscation. Pure and simple.
"Ridiculous" seems to be your understanding of what i write, to be honest . .
IÂ´m not used to reproduce data-sheets or take a calculator but like to tell about real use of my own. Usually there are - surprise, surprise - differences . . .
I tested several speed-modes for some months. Did you do that also for such a long period - and are you in a situation to give judgements about how it works in situations? LetÂ´s hear about it - and letÂ´s see examples which are really good! I clearly wrote that my (!) finding was a realistic use with 35mm@1/500. Using f8 i canÂ´t do that really often in our region without cranking up the ISO to a level i donÂ´t like to do.
Using an 85mm - where it starts (!) making real sense in my eyes in terms of saving time - is nearly impossible to do in our region. ItÂ´s not bright enough.
I ALWAYS stated that speed mode needs VERY bright light. IÂ´m NOT against speed-mode basically!! ItÂ´s a questioun of where you really can use it.
A very important point - the most importan point in my eyes: waiting for the most bright light to use a speed-mode means to not shoot when the light is GOOD - but when it BRIGHT.
Being an advertising photographer used to highstndards iÂ´m used to shoot when the light is most DELICATE - not when it is most BRIGHT.
Because of all that findings in real use and preferring high aesthetical standards i came to the conclusion i stated.
No problem if your standards are different.
i think are more important in real life - i mean: looking into the whole stuff more carefully . . .
is certainly sage advice.
Onto practical matters -
Because iÂ´m rather quality- than speed-oriented i abandoned the speed mode on my head-version of JosefÂ´s. The sensors which prevent exposures at even slightest shaking
This is a very useful feature to have.
Out of interest, what's the quickest time between shots that Josef's head can manage with a 5kg (1d4+400/2.8 II) load?
I didnÂ´t count it - itÂ´s of no interest for me. It works great and i can work with it as it is. But i will take measures for you if you want. Besides: i guess thatÂ´s a question you should ask Josef.
I really donÂ´t understand the haunting for speed. "Speedy" things very often mean excessive editing afterwards.
Did you ever stand in a construction-site shooting a 700Mpx-sphere where everything is in movement?
Using a speed-mode doesnÂ´t save you any time at all! What really helps you is to be able to break the sequence any time you need to and proceed from the same position. This way you can avoid badly wrong positions of cranes and so on.
Josef implemented a fuction that lets you stop where you want and go back one (or more) frame to do the shot again when the movement is gone and proceed shooting - to the next stop or to the end. THATÂ´S a useful feature in real life and for real working - because this is written to the xml and so
you donÂ´t have problems later importing the shots.
Really: speed-mode gives you a pain in the *** in such a situation . . .
It isnÂ´t "speedy" at all spending hours and hours afterwards for editing doubles or missing objects.
Calculating is one thing - practical experience is another thing.
In a high-res pano you can see a stitch-error of some few pixels by zooming in @100% - right?
Using a high-res camera . . and then giving away a part of the resolution for even the slightest pixel-movement . . do you think THAT is clever?
Do you think itÂ´s as sharp as it could be at 100% compared to your cameraÂ´s capabilities?
I donÂ´t think itÂ´s really clever. This is why i refuse shooting with continuously spinning heads and "speed-modes". I KNOW the results - i donÂ´t need calculating here . .
People sometimes have - we read it here several times
- funny imaginations about "wonderful" speed-modes. They seem to solve nearly any problem in just the fraction of time than doing it manually. And these imaginations usually get encouraged by the manufacturers of gadgets. ThatÂ´s ok - they want to sell products. But the clients sometimes donÂ´t know what theyÂ´re gonna buy before they use the gadget in their own real world. You wouldnÂ´t find any limitations of usability in data-sheets . . at least if youÂ´re not very experienced in reading them and understand what it REALLY means what you read . .
I guess everybody made such an experience at least once with one or the other device. I definitely donÂ´t relate that to a dedicated manufacturer!!
