Unfortunately, there is a circular focusing ring in the lens assembly that can get jammed by dust, lint, sand, etc. You can try to blow it out and free it up, however, this requires partial disassembly of the unit. I would take it in to a camera repair shop, and see what they would charge to just check it out, then go from there.
You can gently try to bump the camcorder, in hopes of freeing up the lens, but other than that, it will have to be taken apart.
There are videos on YouTube that show how to do a lot of things, if you go look around there. You may not find your exact model, but you will find a similar item.
Good luck, thanks for using FixYa, and hope this helps.

How to connect vivitar wide angle lens and telephoto to canon t2i


make sure the vivtar lens is "58mm" diameter (shoutstate this near the fron of the vivtar lens) then it should be a question of screwing the lens on top of the other lens. not the best way of getting wide angle shots as the 18-55 is pretty soft in focusing already and adding another inferior lens will make it look poor. if you don't want to buy a lens i would suggest investing in a tripod and take multiple shots with the 18-55 and stitch them together with a photo editing tool like photoshop

I have a vivitar video recorder model no 840 xhd. can you tell me what memory card to get for it. the hand book says I need a standard SD card upto 32GB.but most card have other numbers or letters after...


It can use MMC cards or SD cards or SDHC cards up to 8GB in size.

SD cards top out at 2GB. 4GB and larger cards are technically SDHC (Secure Digital High Capacity) cards.

Purchase Zoom Lenses


Canon currently makes super Telephoto lenses from 300mm to 800mm and a number of zoom Telephoto lenses from 28-300 to 100-400. You can also special order a 1200mm lens from Canon at a cost of $99k! (There are only about 20 such lenses made so far.)

You can also get a 1.4 or 2x teleconverter to further increase the power of a telephoto lens. However, the cameras are unable to auto-focus when the minimum f-stop exceeds f/8, which can happen when you use one (or both) of the teleconverters on these longer lenses, so you have to manually focus the lens.

You can also get telephoto lenses from other manufacturers such as Tamron and Sigma that are built to work with Canon cameras. However, the Canon lenses are generally regarded as the best quality.

Conversion lenses & filters


These screw on the front of the plastic lens adapter and adjust the focal length. On the side of the adapter lenses it will quote the ratio. My wide angle says 0.66x so just multiply the range of focal lengths by this figure and you will see that it adjusts the camera zoom accordingly - making the image wider and probably also increasing the depth of field (what is in focus). Similarly a 1.5 tele will inrease the range of focal lengths to make the lens "longer" eg higher magnification , useful for astro photography - shots of the moon and terrestrial long distance work but detracting from the depth of field, eg the range of distance over which objects are in focus will be reduced.

The wide angle will allow you to come in close and get WIDE objects fully in-frame- hence "wide angle", while the telephoto will give you better overall maginification of the image but will probably increase the MINIMUM focal length - eg you may not be able to focus on objects closer than >2m (instead of ~1).

The screw-on adapter lenses I found were cheap in a Jessops sale use a 52mm thread, while the S5500 provides a 55mm internal thread. I use an appropriate 55mm to 52mm step down ring adapter. There is slight vignetting (shading around the edge of an image) at certain combinations of zoom, but generally these are very useful accessories.

As these are adapter lenses on the front of an already powerful 10x zoom that must be optically compromised at the price of this camera, there maybe some colour fringeing around bright images. If you want a better solution you really need to get a DSLR. Overall a good solution for the price.

How do I know what size lenses to look for?


Hi rlopez117,

Congratulations on the aquisition of such a great vintage camera!

Pentax cameras use a mount known as M42. This means it is a 42 millimeter diamater. You may also find this referred to as the Pentax mount, as Pentax (Asahi Optical) made this popular in the United States. With any camera, any lens you purchase should match the mount of the camera in order to be used together.

Thank you,
Jason,
Go Ahead. Use Us.

Losing focus


Usually this is a back focus problem; also called a flange back adjustment.  If the back focus adjustment is possible on this camera, zoom out wide - open iris all the way - and adjust focus and lock position.

Red eye


RED EYE is caused by the sudden flash from your camera and the eyes reflex reaction to the sudden light. So what the red eye reduction does is to double flash to counter the reaction. You can try adding an external light source to to your subject. in addition to the following procedures for your camera in the manual, the indicator location on page 64 Flash On Flash Off Red-eye reduction C REC modes on page 52, Snapshot; pg 64, have the flash fire automatically when required (Auto Flash) * Turn off the flash ... recording with flash, reducing the chance of red-eye in the image (Red- eye reduction) In this case, the flash fires automatically; Also, be aware of the following: The approximate effective range of the flash is shown below. Wide Angle Optical Zoom: Approximately 0.4 to 2.9 meters (1.3´ to 9.5´) (ISO Sensitivity: Auto) Telephoto Optical Zoom: Approximately 0.4 to 1.6 meters (1.3´ to 5.2´) (ISO Sensitivity: Auto) * Depends on zoom factor

S70 Macro Focus Problem?


The macro is good at 4cm at wide angle, 8inches at full telephoto(different distances for any focal length in between). I read that someplace in the manual, I believe.
