martz 0 #1 January 26, 2005 Why don't use a fd lens ? I saw that the best way is to put the lens in manual focus and set the focus at around 3 feets. Why do I need a EF lens if I don't use the autofocus ???=============================== Ourson # 5 impatient de sauter # 1 Quote Share this post Link to post Share on other sites
dragon2 2 #2 January 26, 2005 Because an EF lens also lets your automatic camera take care of the diaphragm/shutterspeed combination. If you use a manual lens (Zenitar for instance or older Canon/Nikon/whatever lenses) you have to set the diaphragm and the shutter speed by yourself. Can be done of course, everybody USED to do it, but if you don't know what you're doing you could end up with bad pics. ciel bleu, Saskia Quote Share this post Link to post Share on other sites
martz 0 #3 January 26, 2005 Ohhhh thanks .. I'm really a newbie with camera ... so I'll stick with EF-AF lens .. Thanks a lot By the way .. setting it to manual focus at 3 feets is correct ?=============================== Ourson # 5 impatient de sauter # 1 Quote Share this post Link to post Share on other sites

The other problem with the FD lenses is that they will not fit on a newer EOS camera, unless you use an adapter. Manual focus at 3 feet is a bit close, I set mine more around 5 or 6 feet, just under infinity. Quote Share this post Link to post Share on other sites

What do you mean with infinity ?? you lock the focus with gaffer tape ??

vdschoor 0 #6 January 26, 2005 QuoteWhat do you mean with infinity ?? you lock the focus with gaffer tape ?? Thanks again You set the focus to a little bit under infinity, look at the attached image for what the infinity symbol looks like. I tape the focus ring with gaffers tape yes. From your questions it sounds like you are very new to this, which is cool.. it's a whole lot of stuff to learn. I would recommend reading the manual of your camera before you start doing stuff, make sure you're totally comfortable with the controls and have at least a basic understanding of what things mean before you jump it.

martz 0 #7 January 26, 2005 oh yes I'm very new to still camera. But it's like everything else ... i'm gonna learn ... And your help is very appreciated I'll look at my lens ... thanks=============================== Ourson # 5 impatient de sauter # 1 Quote Share this post Link to post Share on other sites
bmcd308 0 #8 January 26, 2005 You can still use stop down metering and let the camera pick the shutter speed based on the aperture you pre-select. http://photonotes.org/articles/eos-manual-lenses/#what ---------------------------------- www.jumpelvis.com Quote Share this post Link to post Share on other sites
bmcd308 0 #9 January 26, 2005 http://www.vividlight.com/articles/2314.htm Setting the camera at infinity "wastes" a good bit of depth of field. Pulling the focus closer to the hyperfocal distance gives you a similar level of sharpness at infinity and allows you to achieve sharper images at closer distances.

Like I said in my post, I don't use the infinity setting, but instead my lens is set at a little below infinity.. About 6 / 7 feet out.. For my lens (28 mm) that's a little below the hyperfocal point is what I find from that spreadsheet.. I'll do some more testing with it this week.. thanks for the hint!

blazetailman 0 #11 January 26, 2005 Using aperature priority is a bit sketchy for freefall if the light is starting fall at twilight and if a dark (black ) jumpsuit or whit are in the frame. Setting your camera manually with the sunny daylight rule works best for noraml light conditions. 125th @ f16 for iso 100. or any corrected exposure from this. I'll look for a write up on this. Its a basic rule but works 90% of the time. Here is one that I think explains the rule in abasic manner. I think a lot of photogs make it way too complicated and get too technical with it. http://www.explore-art.com/photography/S/Sunny_f%5E16_rule.html I'll look for another that explains the process in a simpiler manner.www.canopyflightcenter.com www.skydivesac.com www.guanofreefly.com Quote Share this post Link to post Share on other sites

The relationship between plane of sharpest focus and depth of acceptable focus is something that takes lots of new photogs a while to get, and an understanding of hf distance often helps. ---------------------------------- www.jumpelvis.com Quote Share this post Link to post Share on other sites

NOT true, before I bought an Auto focus camera I used an Canon A1 and an AE1 program, BOTH allow you to use either aperture or shutter priority and they both also allow you to go completely auto EXPOSURE, what they don't do is auto FOCUS. Martz would benefit from going to Kodaks' website (or one of the thousands of other very good instruction sites) in the education section and reading up on Hyperfocal distance, and basic photography techniques. As for the 18% grey, shaded green grass does a fair approximationYou are not now, nor will you ever be, good enough to not die in this sport (Sparky) My Life ROCKS! How's yours doing?

NOT true LOL, if you put a manual lens on an automatic body (this is about a Canon EOS I think) it will only work on aperture-priority. This may be because you need an (not-so-smart) adapter to get a zenitar type lens or an FD lens on such a body. ciel bleu, Saskia Quote Share this post Link to post Share on other sites
