			<description><![CDATA[Yeah, I'll hunt around a bit. At least the lenses are cheap, if I'm debating over 2, both of which are £5 I may just get both of them, one can be a spare if I don't use it much.

So is there any real reason why a lot of animators seem to use Nikkor? Do they give higher quality, or is it just because they're a bigger company? Seems a lot of brickfilmers go for Nikkor to me.]]></description>

			<description><![CDATA[Just to be sure: don't stare yourself blind on the "Pentacon" brand. There are lot's of other brands from that era that offer similar quality M42 lenses. Alternatively, you could try the Nikkor lenses but these are a lot more expensive than the less popular brands, plus, you'll need a more expensive adapter...]]></description>

			<description><![CDATA[I've got a 29/2.8, a 50/1.8 and a 35-70 zoom lens. Plus, of course the macro rings and an adapter.
I use the 29 for about 75% of the shots, the 50 for 20% and the 35-70 for the rest. So you should be covered with a 29mm and a 50mm...]]></description>

			<description><![CDATA[[quote=boardron]Basically, the light flicker is caused by the canon lens.
- the aperture opens to get max light onto the sensor, 
- just before the actual picture is taken, the aperture closes to the set value,
- after the picture is taken, the aperture opens up again.
So each picture, the aperture closes to the set value, but unfortunately, it does so a little bit differently each time: sometimes the aperture is a little bigger (more light) sometimes a little smaller (less light). Ergo: light flicker! Makes sense?
Solution: use lenses that keep the aperture REALLY fixed. For OBD (see sig) I use 40 to 50 year old manual lenses: pentacon with an M42 mount and an adapter. These are not terribly expenive where i live... I got 3 lenses plus adapter for under 80 euros.
I got this information from the DragonFrame site...[/quote]
Yeah that matches up with what I read on SMP, even though I do use dragon. What lenses to you use? I've wanted to get some old M42 lenses for a while, but I'm not sure what the best ones are. I see a lot of old lenses for old pentax cameras (I actually have one) in charity shops, but they are made to fit the pentax k series, so it may be hard to get an adaptor. I'll look out for M42 lenses at boot fairs when they start again, I'd just like to have an idea what to look out for. 35mm and 50mm are good animation lenses I think, right? Thats what mobiledeli uses I think, with close focus adaptors (which I've got).

And thanks too ANP, although I think that if that was the problem I would have had this problem for ages, I've used the same lights now for years.

Thanks for the help everyone :)]]></description>

			<description><![CDATA[I found that sometimes, lights you may have a slight flicker. But the flicker is so fast that you can't really see it. But if you take several pictures with a short exposure, you notice a flicker due to the pictures being taken at slightly different times in the light source's flicker cycle.

The solution to this problem is simply give the camera a longer exposure, which kinda generalizes it so you can't see it.

That happened to my while filming I Am The Darkness, since the string lights I have apparently have a super quick flicker, so I put the exposure to something that was a second or more, and it stopped.
:)

However, if that's not your problem, I'm not really sure. :P
(Could be worth a try)]]></description>

			<description><![CDATA[I too have a Canon 550D and use the lens you are using. I have virtually no light flicker. I make sure I'm on manual mode, I turn off auto lighting optimizer, turn the lenses' IS (Image stabilization) off, set a custom white balance, and then make sure to activate the shutter a good distance away from the set and return to the same general position each time I take a shot. Wearing dark clothing can help as well. 

Occasionally I will have some light flicker (sometimes its cause I just lightly bumped a lamp just a tiny bit. This can affect it.) When I do have flicker, I go in and adjust the brightness of the problem frames individually until they are in line with my other ones. This actually works quite well and does not take too long depending on what software you use. Hope some of this helps! Let me know if you have any questions. :)]]></description>

			<description><![CDATA[I tried that, no luck. I read on stop motion pro that the lens can cause flicker, if its digital it won't stop down to the same aperture each time, meaning the amount of light being captured will vary, apparently. I'm using my old camcorder for now, I'll try to get an old lens for my next film.
Thanks anyway. :)]]></description>

			<description><![CDATA[Hi! I had the same problem recently with my Canon EOS 60D with the same lens you have. Well, as far as I am concerned I had to film a scene with no lot of light, with dim light. After my first test, I could see some light flickering. So I tried a longer shutter speed and reduce the aperture to keep the same exposure I would, and it was better like this. I don't know for your scene it can work but you can try!]]></description>

			<description><![CDATA[Hello everyone, haven't been here much but I'm still making animations, and I am currently working on one for school.

Its a plasticene film a bit like Morph, and I really want to get going with filming this but I'm having some problems with my camera.
The main problem I have is light flicker, I'm animating at 24fps, have all my camera's settings on manual (and I mean ALL of them) and there is virtually no light from outside coming in. I need to have this done in a week's time, so I'm a bit annoyed this is happening, anyone got any ideas? I'd be really really appreciative! :)
I'd also really appreciate if someone could tell me the settings they use (what aperture, shutter speed and iso). What's best?

By the way I'm using a Canon EOS 550D with the 18-55mm lens.
Thanks.]]></description>
