Folding optic lenses are the type of lenses that fold back into the digital camera's structure. These lenses are great to keep things very compact but don't let you use converters that go on top of the lense to get a dissimilar look and feel to the picture.

Fixed Zoom Lenses don't retract, but they can magnify something by up to 18 times its primary size. Business photographers use these types of lenses often. This type of lens is great for a serious amateur photographer.

Fixed Focal Lenses do not have an optic zoom feature, but they normally have a digital zoom feature. The best part about these lenses is they have easy settings and are great for taking wide angle shots as well as pictures of landscapes.

Retractable Zoom lenses are what you find in most of today's newer compact cameras. They retract into the cameras frame so that you can't damage the lens if you were to pack your camera nearby for travel. The settings and switches on this type of lens are very minuscule as well.

Interchangeable lenses are the grand daddy of them all. Any serious photographer will use these type of lenses as they save you money because you can buy dissimilar lenses and not dissimilar cameras to get a desired effect.

Buy Your First Canon Digital Slr Lens - 4 Questions to Ask Before Buying

Decisions, decisions! Which Canon Digital Slr lens should you buy?

[b]Lens[/b]

It was probably a explore and decision process just to decide on the right Canon Eos camera, right? But now you are faced with a huge sea of lenses, both by Canon and by third party manufacturers.

So which one do you choose?

Of course, you could just pick up the package deal that includes what is know as a kit lens. And there are even packages that consist of two or three kit lenses that cover a wide spectrum of focal lengths. Then there would be no decision.

However, if you are a discerning shopper, you will want to get the best Canon camera lens possible for your money.

Some new digital Slr owners agonize over this decision for days, weeks, and months. In fact, there is a posted question on one of the camera forums that is over two years old, and the traditional poster has not yet made up his mind. Now that is a bit extreme.

But the truth is, you want to make sure you get a lens that will serve your photography needs with the best capability photos possible.

This brings up the question, "Why not just get the kit lens?" The acknowledge is a easy one. While the kit lens is enough as a beginner Canon camera lens, it is not the best lens they make. Its purpose is to get a lens on that camera so you can get started taking pictures right out of the box. Many buyers opt to get just the camera body and buy the lens or lenses for their camera separately.

Here are some questions that will help you narrow the field.

1. What is your budget?

This may just be the only question you have to answer. If your funds only includes the camera and a kit lens, then you are done. If, however, there is some money allocated for a lens, you can think about the remaining questions. A dinky funds of 0 or less will put you in one area, whereas 00 will give you much more flexibility in your final decision.

2. What type of photos will you be taking the majority of the time?

You probably have a preference as to the types of images you prefer to capture. After all, most folks do not buy a digital Slr camera as their first camera. If you take lots of snapshots of family and friends or vacation photos, possibly the focal range of 18-70mm (or something within those parameters) will be perfect. But if nature, sports, or portraits are your popular types of images, the ranges you reconsider are going to be much different.

3. Will you be buying more than one lens for this new Canon Digital Slr camera?

Buying more than one Dslr lens is surely the second reason why most photographers move into Digital Slr photography, the first reason being their desire to get a more sophisticated camera. If you funds allows for another lens or two, then the first lens selection can focus more on getting the best image in the 17-75mm range. Your second lens should be one of the 70-200mm or 70-300mm lenses.

4. Which Canon Eos camera did you buy (or will you be buying)?

This is an foremost question that may eliminate a few lenses from your consideration. If you buy one of the entry to mid level digital Slrs, you can buy practically any Canon Ef lens or third party lenses made for Canon. If, on the other hand, you buy a more professional "full frame" camera, you can not get any of the lenses that are designated at Ef-S lenses, as they are for only the crop frame models such as the Rebel series.

The decision to move to a Dslr camera is an enthralling one, but it is not without its explore and challenges. You surely need to do your homework before manufacture this buying decision.

#2 Digital Camera mend problem - Broken Lens

We live in a throw-away society, it's a simple fact. You buy that brand new fancy digital camera with all the bells and whistles for 0, and in 6 months to 1 year it's worth maybe half that, and then the unthinkable happens: you drop it and it breaks. The Lcd is cracked, or the lens is jammed; what do you do?

[b]Lens[/b]

You can get digital camera repair for a lot of money, or if you shop nearby you can get find affordable digital camera repair on the internet! Gotta love the internet!

There are options, there are all the time alternatives to every problem. Honest! Yes, it may cost 0 to fix your camera, and yes you can buy that camera in the bubble pack on the shelf at W**l M**t (they don't pay my bills... I don't advertise their name, sorry) for less than 0, but what kind of ability do you genuinely expect from a 0 camera? Not very good ability I hope, because you're not going to get it.

Ok, digital camera lens repair is as common as Lcd repair, but it's #2 on my list because it's harder to repair a digital camera lens and there are so many different types of lens problems whereas a broken Lcd is a broken Lcd no matter how you look at it.

- Do not leave the batteries in your camera in the camera bag. The power button can be pressed accidentally causing the lens to expand and get jammed because it cannot open properly inside the bag. - Try not to drop the camera with the lens extended. - Don't ever pull or twist on a lens that is not working 100% properly, you will just break it.

I would have to write a book to fully expound lens problems fully (hmm.. Maybe a good idea!) so I will try and keep it simple and informative.

The lens is made up of many different parts... Let's start with the several pieces of glass referred to as the lens elements. The outer lens element is prone to being scratched and scuffed, and usually has a extra coating on it that you Do Not want to clean off with isopropyl alcohol (rubbing alcohol), or Windex or something similar. It's not the end of the world, and don't worry about it if it's missing. Just keep the lens clean (why are there fingerprints on your lens anyway??) and scratch free.

The inner-most lens element is responsible for the fine focus and resides directly in front of the Ccd. When you press the shutter button half way down to focus, this part moves forwards and backwards till it's in the accurate position and your image is in focus. You won't be messing with this part of the lens... Unless you feel like removing the lens from the camera and then tearing down the lens to get at it's 'guts'. It's kinda fun the first time, but uh... I wish you luck getting it back together properly. The tearing apart stuff is fun, the putting it back together is a drag!

The lens has two small motors with their own gears that join together to the two main parts of the lens. The larger motor drives the lens barrel in and out when zooming. The smaller motor drives the fine focus element mentioned above and controls the focus. If you get One Grain of sand in these gears, they will jam and the lens will "error out" as we like to say. Open it up and clean it out if you like, but it's not easy. Typically the main motor of the lens has 5-6 different gears that must be set and aligned properly to function. But hey, your lens is already jammed, why not see how it works, right?

Then there is the Ccd, "charge-coupled device" which translates the light that enters the lens into a digital signal that the camera can record.

There was a very large Ccd recall for Sony camera lens repair over the past few years that covers many manufacturers and not just Sony, as Sony provided the Ccds to many others for their cameras. The defective Ccd's cause the camera to take solid black photos, or purple/pink "dripping paint" photos, or they have repeating white horizontal or verticle lines on the images. If your camera does this, call the constructor and tell them you want a repair under the Ccd recall no matter how old your camera is! If it's on the list, you might get your camera repaired for free.

Got spots on your images that get bigger and smaller as you zoom in and out? Most likely there is a spec of dust on your Ccd. You will need to take off the lens and then take off the Ccd from the back of the lens and clean it off. Don't lose the gasket that goes nearby the Ccd, don't get any other dirt inside the lens and don't leave any fingerprints! Tall order I know, sorry, I'm demanding. =)

Let's see... What else? Your lens is part way out, stuck at an angle because the camera was dropped while turned on. Now please read that carefully; the lens must be stuck part way out or all the way out, and one section of the lens Must be stuck at an angle. The lens must not move freely at all for this section to apply, and you may consequent this advice At Your Own Risk. The following repair trick works, but I am not responsible for your actions or anyone you do to your camera.

Ok, it's stuck at an angle and you want to try and repair your camera lens yourself. No problem.

Hold the camera with the angled part of the lens resting against the edge of a table, and the rest of the camera hanging over the side. Do not place the camera facing down with the "Canon Zoom Lens..." chrome ring section flat on the table. The rounded edge of the lens must be what makes palpate here. Now... Here is the tricky part... Press the angled part of the lens back into alignment by pushing down on the lens on the edge of the table. Put your fingers on the Lens below the angled part to withhold it and press firmly but still gently (how do I do that? I don't know.. You just do it) and the lens will whether Pop!! back into place and work perfectly or it won't budge and no harm will be done, -Or- one of the "guide pins" that run inside a small track in the lens barrel will break off and you have just destroyed the lens.

I told you it was at your own risk!! Camera repair is fun... Right?

Ok, how are we feeling about lenses? I think we have covered most of the basic problems, and potential solutions. If you want to buy a lens for your camera there are several ways to do it which comprise calling the manufacturer; but they will want 5+ for the lens, guaranteed.

Do a Google hunt for "digital camera parts" and you will see at #1 the only site that has affordable digital camera repair and Diy parts.
