lens only works in the house
Aug 25, 2015 21:26:43 #
this is the only lens that I had trouble with. All my others work fine. I will try the web search and see what I come up with. Thanks for the suggestion.

the same thing happens when I try the manual focus. I tried all over outside when the sun was shinning. tried shutting in the shadows, in the bright lite, with the flash and without the flash. I did get it to take a shot at only around 6 ft looking one way on my deck but not the other way. The deck is somewhat shaded. I just went out now to try it. It is 8:30pm and dusky. the flash went up and it worked every time. Must not like the lite. It must be a part time lens. I will keep investigating. I just thought maybe someone had a quick fix. But I know about quick fixes. they are hardly ever there. lol

Have you tried removing the lens and stopping it down manually?I have a cannon Rebel xti and got a quantaray 75-300 mm lens. When I try to use it outside it says to put in new batteries. I tried this, put the lens on and off, cleaned the connections. I tried it in the house and it works there. I tried to change the settings on my camera, but that didn't seem to make a difference either. My daughter in law tried it in her camera and it doesn't accept it either. I thought it was supposed to be compatible, but maybe not. Any ideas????

"Quantaray lenses are relabeled lenses from other manufactuerers (mainly Sigma iirc). In your case, the lens is not compatible with digital EOS cameras, and eventually it's not compatible with the latest film EOS that came out as well.
The problem is usually an errormessage as soon as you want to stop down ... when you use the DOF button, or when you press the shutter button.
Sigma did rechip some of their lenses (the newer lenses have loadable firmware). Depending on the lens, Sigma might (or might not) be able to rechip the lens." This is from 2007
So your in a bit of a bind here, canon lens are controlled by an electronic interface, with coded signals coming from the camera and coded response codes being returned from the lens.
As said in some film "what we have here is a failure to communicate".
Trouble is canon doesn't just give away the protocol (language words used) for it's camera to lens communications. So third party lens manufacturers reverse engineer it. They essentially monitor the signals and timings and get their lenses to mimic the canon ones.
However protocols tend to evolve and extend so you have version 1. version 2. ect.
Canon probably has an identifying code on it's lenses so the camera knows which protocol to use. keeping older canon lenses in use.
For third party manufacturers, when new models of canon bodies come out they need to release upgraded firmware in order for the lens to work correctly on the newer bodies.
Quantaray don't make lenses, they rebadge third party lenses. This means you need to figure out who the third party is probably tamron or sigma and find out if you can get the firmware updated or the chip replaced.
I don't know the lens but if it has an aperture ring then you may be able to use the lens manually. Perhaps via a teleconverter which will keep the camera happy, without confusing the lens. If i mount a pentax lens on a canon there is a chip on the adapter which tells the camera its a f1.4 50mm lens and the body works with the lens. You might be able to get one of these chips and fit it to your lens. An adapter wouldn't work because it would put the lens out of registration distance and it wouldn't focus to infinity.
I'd try the teleconverter route first see if you can work with it that way.
Alternatively you could use the lens on m43 camera's it would attach via an adapter, these camera's will work with no detected lens attached and have a short registration distance so will happily work away manually.
Other than that, the lens would be junk to you but to owners of older canon film camera's the lens would be good also to m43 owners sony owners who would be using it via an adapter.
It might be ok as a macro lens with some cheap extension tubes.

Canon users can explain the details better than I can, but, unless the lens is very old, its natural state unmounted should de wide open. There should be some sort of device that allows you to physically stop down the lens. When mounted, you view at full aperture and your lens stops down to the preset aperture just before the shutter fires. If this device is not working, all of your pictures will be shot at the widest aperture. Some cameras will not allow the shutter to operate if the lens does not stop down. Indoors, you may be shooting wide open anyway, which will not affect the shutter safety lock.

Sound like you're in a quandary with that Quantaray. :D
If anything, I would expect the opposite - wanting batteries inside the house because of lower ambient light. Try using it inside pointed at a brightly-lit area. Has this ever worked outside?

You must always shoot with wide open aperture at all focal lengths. I had the same problem with a Sigma lens. Set the camera to manual mode or aperture priority and adjust shutter speed accordingly. Hope this helps.

I noticed that you have a Quantaray lens. I have two of them. I am sorry for you.

Ok, I'm going to be a little harsh here. You don't know what exif is. You don't know what "stopping down manually" means. I suggest you learn to use your camera before you start investing in a bunch of fancy extras. All you are doing is frustrating yourself.

Food for thought, check on canon site and see if there is firmware update or if you have the most current.
if you have the most current, you may want to try to reflash the camera again in case there is a corrupt bit.

Try turning Auto Focus off and shoot manually. Does it work outdoors then? The whole situation sound absurd but there is something odd about that lens (likely the contacts on the lens or firmware in the lens). It makes no sense. Yes, repost your photo(s), check "(store original)".

One possibility has to do with the soft shutters:

Try a manual camera and a manual lens. Automatic everything I have no time for. :thumbdown:
