I'm not much given to laying down the law or to providing rules about photography or anyone else but I'm going to tell you now that if you want to take super sharp photos you're going to have to do something about your selection of lenses.
I'm going to start with a piece of clear advice.

It's this: Lenses are more foremost than cameras. Yes, it's true, Lenses are more foremost than cameras. A camera is just a light tight box attached to a lens.

This means that if you want to take super sharp photos you must have lenses that you can rely on to make this happen.
Now, if you want to choose your lenses you're going to have to take inescapable factors into account.
Are you going to choose a lens which has a camera constantly attached to it? Are you going to choose a lens or lenses where you can attach different lenses to a camera? - these are interchangeable lenses. Are you going to choose lenses with a fixed focal length, sometimes called prime lenses? or are you going to choose zoom lenses?
Just in case you're not clear what these terms mean, a fixed focal length or prime lens has just one focal length: 28mm for a wide angle, 50mm for a standard, 100mm or more for a telephoto and so on.
A zoom lens of procedure is very favorable because it makes up a holder which can include different focal lengths so you can buy a lens which can go, for example from 28mm to 200mm.
Now, before I go any additional I'm going to tell you that it is possible to buy zoom lenses that can help you to take super sharp photos.
But and there is a but, it is likely that such lenses will be very high-priced and rather heavy. There are some exceptions but you need to choose carefully. So, let's have a look at some of the things we'll have to think about.
First of all every lens has a maximum aperture.
So called wide aperture lenses have a lot of glass and a maximum aperture of somewhere colse to f2. There are some reasons for preferring lenses with a wide aperture:
They allow more light in - this means that you can take sharp pictures when the lighting levels are low.
It's much easier to focus with a wide aperture lens.
Auto focus systems work good and if you focus manually you can see more clearly.
Wide aperture lenses give you much more operate over depth of field (Dof).
Dof is very shallow at wide apertures and this can be vital for some pictures - portraits for example where you want the background out of focus.
So, is it good to choose prime lenses or zoom lenses? Let's have a look at zoom lenses first. Zoom lenses are very convenient. And they have some clear advantages. From my point of view the main advantages are:
You don't have to turn your lens so often.
This means that when the elephant charges towards you, you won't have to fumble colse to choosing a different lens and you'll get less dust on your sensor if you don't turn your lenses much.
The other advantage is that you can frame your photo in many different ways from the same spot.
This can be a big help sometimes but I have a special accessory - it's called a leg. Often the best arrival to changing your composition is to walk. And there's a problem: The more favorable and flexible a zoom lens is, the harder it is to get a good quality, wide aperture lens which you can afford and carry.
Many favorite zoom lenses marketed as super zooms and most of the kit lenses supplied with many cameras are perfectly favorable for casual use but they are not going to give you super sharp pictures.
I'm saddened when people have spent a lot of money on buying a capable camera and then use a less than top ability lens.
So, if you want to buy a zoom lens and you want to take super sharp photos, look for a zoom lens with a constant wide aperture and a moderate zoom range. Like many photographers I use a zoom for my walkabout lens - a lens I can take with me to the mountains and fields, a casual stroll and use for many types of photos. I commonly use my full frame Canon 5D Mark 11 and for this I have a Tamron 28-75mm Sp zoom lens. This is a fine lens - especially when price is a consideration. However, if you're interested in super sharp photos, it's worth having a look at prime lenses.
Prime lenses have a lot going for them:
They're easier to fabricate and simpler to fabricate than zoom lenses.
Wide apertures come as standard.
They are less likely to show distortion.
Now you can pay the proverbial arm and a leg for wide aperture prime lenses as well as zoom lenses, so where are the bargains? First of all, every camera maker has a appropriate lens - that is a lens of colse to 50mm focal length. These have been colse to for a long time and the ability is good.
One example in the Canon range is the Canon 50 mm f1.8 often mentioned as the best bang for your buck - but there's a downside. The construction is, well a kind word is cheap - it's plastic almost everywhere. The focussing is pretty old style and the hand-operated focussing ring is skimpy.
But the glass is top notch and this lens with its wide aperture is well up to the appropriate of my full frame Dslr and is a great portrait lens with a crop sensor camera. And it's very light so you can carry it all day long and if an emergency should happen you can replace it for about 0.00.
Using a appropriate lens makes you take a disciplined arrival and you can use it in many different situations - especially if you're willing to use your legs.
Another way to be sure of getting super sharp optics is to choose a macro lens.
Macro lenses are specially corrected to take 1:1 size pictures of objects such as coins or insects. But they make super sharp general purpose lenses. I used the Tamron 90mm in my film days and now use the Canon f2.8 100mm Macro lens. Macro lenses are not the cheapest but they do supply great value for money and extra versatility. A word of warning: check that the lens certainly is a macro lens. Some fellowships use the word macro loosely to mean half size or even just fairly close focussing.
So let's just say it again, lenses are more foremost than cameras. And if you want super sharp pictures choose a fixed focal length prime lens or a zoom lens with a moderate zoom range, a constant wide aperture and good glass.
Just to clear up one point - what happens if you want to buy a lens with the camera attached?
My personal notion is that the marketing gurus tend to emphasize the cameras rather than the lenses. Also, modern digital cameras are made by former camera makers like Canon and Nikon and the new kids on the block like Sony and Panasonic who have great expertise in electronics. Some manufacturers like Sigma and Fuji yield cameras with special wide aperture high ability wide angle prime lenses. There's one other point, some of the new fellowships have teamed up with predominant lens makers: Sony with Zeiss, Panasonic with Leica and I've seen Hp cameras sporting Pentax lenses. This can be a help as these predominant lens makers won't put their name to poor lenses.
Also, read the reviews and forget the bits about the megapixels and zoom range and combine on the comments on lens quality. I like to check dpreviews and the pages from photographer Bob Atkins to get some good guidance on lens quality.
Just to desist my guidance at this point: Once you have chosen a super sharp lens, it's vital to know how to use it.
Yes, using your lenses properly can make all the difference. That's in my next installment - "Using Lenses".
