Question about Cameras

1 Answer

I have a 1 year old Tamron 18-250mm lens attached to Canon eos 400d. Have been using with no problems untial last few days. The auto focus only works intermittently - causing me to miss several shots. If I twist the manual focus ring a couple of times - this restarts the auto focus for several shots but I then might have to repeat process later.

Try cleaning the contacts on the camera body and lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

Have a two month old 18-270 Tamron lens. Used it a


If it's only two months old then it's still under the manufacturer's warranty so send it back to Tamron. I can't tell you where to send it as you haven't said which country you're in. Tamron value their reputation and usually provide excellent after-sales care.

If you're in the UK you additionally have Sale of Goods Act protection for up to six years in England and Wales and five years in Scotland. Either way, the Act allows you to demand a full refund or replacement from the retailer; I'd suggest a refund as bad lenses often come in batches and a different supplier is less likely to have one from the same production batch.

Note that any attempt to fix the lens other than by normal use of the lens and camera controls may completely remove your warranty benefits or consumer protection.

Sometimes when i'm taking picture my flash wont stop blinking for a few seconds.


The 400D uses flash assisted focusing. In low light conditions the auto focus cannot get a focus lock so it pops the flash a few times so the lens has a chance to focus. You will notice this will go away when in the manual focus mode (the switch on the side of the lens).

The only way around this problem (as people in a photo think the photo has already been taken and looks away when the camera actually takes the picture) is to use a hotshoe mounted TTL Canon Speedlight (430ex or 580ex) which use an infra-red focussing beam.

I want purchase a zoom lens 55-250,70-300,75-300 for my Canon EOS 400D camera what is the price range?


If you are talking about canon only (not sigma/ tamron etc) lenses then there are many different variations of the above lenses ranging from a few hundred to over a thousand UK pounds ( I dont know your currency/country) If you are looking at the budget market then the best value of the 3 mentioned id the 55-250 by canon which has good optical quality and built in IS (Image stabilistaion) and is remarkable value for a CANON branded lens

Other option in the price range would be the 75-300 mk III but it is non IS but does give you a longer reach.

Contact Canon - some makes of lens which are not Canon are not electronically compatible for various reasons, and can actually damage the camera. So, get using the phone and check if it is compatible before doing anything else - but personally, I would not use the lens until I find out

Attaching it to a Canon EOS 400D REBEL XTI


Totally different lens mounts, you might be able to get an adapter ring, but it wont function amazingly. Honestly, you're better off just selling this lens and buying a Canon 70-300 instead.

Tamron lens for Xti?


if it is an auto focus lens that works on one eos camera, it should work on almost all of them. the only known exception is that some high end extenders will not fit the eos1dmarkII as it protrudes into the opening too far.
but a good rule is that if it fits without any obstruction issues, it should work. try cleaning contacts on the lens and camera body. if that doesn't fix it, talk to Tamron. you can use it manually, but will not be as easy and you would get less predictable results.

my suggestion is to always go with lens from camera maker.

sounds like there is an issue with the tamron lens. not the camera.
good luck

AF 70-300 causes error 99 in my Canon 300D


This is usually a torn flexible circuit or binding aperture in the lens. It'll have to go to a repair shop for replacement. About a $80 job.
