How do I manually set focal length?

I have a 9mm BCL on the camera and I want anti-shake to work. The lens booklet says to "set focal distance to 9mm". I think they mean "focal length".

SOURCE: If you zoom to less than 12x

The macro setting on the fz series allows you to get within a couple of centimeters of the subject and obtain focus. That is pretty close. That is too close. The camera will throw a shadow. You need some room. Most high zoom cameras (notably Olympus) have macro capabilty throughout the zoom which not only increases the magnification but also allows you (requires you) to put some distance between the lens and the subject. The panasonic fz series is different. They do not have macroability at zooms greater than 2x-3x. Beyond that there is no increase in magnification. Why? I dont know. Maybe this feature was designed on a Monday. Fortunately this can all be rectified with the use of a closeup lens. Now the fz series will react like most other high zoom cameras and do it well. The Olympus b-macro is such a lens. There are many others

SOURCE: AF problem with Quantaray 2X adapter

I believe a tele will not work with auto focus when the lens is f4 or larger at the smallest end.

SOURCE: SB-600 Power Zoom stuck at 14mm

I struggled with this one but then, on the basis that if all else fails read the manual I found the answer. It's soooo simple. The wide-flash adapter is set. That's the little pull-out screen at the top of the flash which folds down over the flash-head. If it's pulled forward it activates the wide angle setting automatically. Push it back in and you'll be fine. tony k

How do I zoom in and out on a photo?


This camera has a 9mm lens, and while shooting, you can't zoom. For that you need a zoom lens. You can buy one from Samsung.
I checked the manual, and it also does not show how to zoom in on a picture when it is on the display. So I guess, you should view it on a computer, or tablet ant use the picture viewer on that device to zoom in.
Be aware you have a great camera and the result with a prime (one focal length) is superior to the results make with a zoom lens.
But if you don't like to move around, to farm the picture, a zoom lens can be convenient.

What does 35-88mm mean in feet? This is a telephoto lens on a Nikon F50 SLR. Thank you. Amadeus


35mm is about 0.115 feet (a bit under an inch and a half). 88mm is about .289 feet (a bit under three and a half inches). They refer to the minimum and maximum focal lengths of the zoom lens. They have nothing to do with the distance from the camera to the subject.

The focal length of a lens is a measure of an optical quantity. It may or may not have anything to do with the physical length of the lens.

How do you take a pic with the Nikon d60 where the background is blurred?


You're trying for what's called a narrow depth of field. DoF is controlled by three factors: distance from camera to subject, lens focal length, and lens aperture. The closer the camera is to the subject, the narrower the DoF. The longer the lens focal length, the narrower the DoF. The larger the lens aperture, the narrower the DoF.

Get as close to the subject as practical, and use as long a focal length as practical. I realize these two aims conflict with each other. For portraits, you want a focal length in the 50-90mm range and move in to fill the frame.

You want to shoot with as wide an aperture as you can. Unfortunately most lenses are not at their sharpest wide open. Also, the 18-55mm lens doesn't open up all that wide, f/3.5 at 18mm and f/5.6 at 55mm. To get the widest aperture, you can shoot in the P or A modes. If you don't want to leave the point&shoot modes, try using the Portrait mode.

Since you're not paying for film, I suggest you experiment with the different settings and shooting setups, moving closer and farther from the subject, using different focal lengths, and using different apertures, and see what results you get.

I want to take a picture that is focused on the subject, while everything else in the picture is blurry


What you want is a limited depth of field. There are three factors that control the depth of field: subject distance, lens focal length, and lens aperture. The greater the distance, the wider the DoF. The shorter the lens, the greater the DoF. The smaller the aperture, the greater the DoF.

One problem with compact cameras is that they have very small sensors. This means that they have short lenses. And short lenses mean they have wide depth of field. This is often an advantage, in that more of the scene is in focus. Unfortunately, this works against you when you don't want a wide DoF.

At the short end, the S2's lens focal length is 6mm. This will put just about everything in focus. Even at the other end, the focal length is 72mm. With a 35mm film camera, most portrait photographers use lenses at least 85mm in focal length in an attempt to minimize DoF to draw attention to the face and blur the background.

Unfortunately, the best you'll be able to do is to set the camera to the portrait mode, get as close to the subject as possible, and zoom in as much as possible. I realize the last two conflict with each other, you'll just have to find the proper balance for whatever you're photographing.

Sigma 70-300mm lens defaults to manual focus


It will default to manual through the viewing screen. It will only work on automatic, using the viewfinder. Make sure you also set the focal length (lens to shutter distance). You might also have a mf / af switch on the lens. This also only works through the viewfinder.

I am trying to take pictures of pennies and I can't get the camera to focus and get a clear picture. Do you have any ideas?


All cameras have a minimum focal length. That is the minimum distance they have to be from an object in order to focus clearly. If you have a digital camera with changeable lenses, that minimum focal length is determined by the lens and how it is constructed. If you have a fixed lens digital camera then the manual should tell you what the minimum focal length is.

One other thing to keep in mind is that on most fixed lens digital cameras, there is what is called a macro setting. If you switch to macro mode, it will allow you to get closer to the object and still get a good focus. Your manual should tell you how to turn on that mode.

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.

Trouble focusing with sigma 70-300 DL macro super lens


It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.

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.
