Hi guys,

I have just bought my first ever DLSR and been practicing with it since day 1 of its birth. Most of the time i am not satisfied with the pictures taken. I know there's a lot to consider for such results like more practice, more research and studies, better equipments, etc.

I've been doing my research and i noted one of the consideration to improve shots is to identify you lens sweet spot. So how do u exactly identify such?

please help.

it is usually 2-3 light stops down

put your cam on a tripod, shoot at different aperture. Crop 100% and see which is the sharpest

Yes basically your aperture controlls the light stop

Example Lens biggest aperture = 2.8. 2/3 light stop downs means 5.6/8.0 respectively

...
so basically, the most important thing to consider for sweet spots is the aperture?
No. Obviously the centre of your image will be the "sweet spot" compared to the corners...

On most lenses (most good lenses anyways) however, the corners can be just as sharp as the centre at ~ f/8 provided that everything is in focus.

Its more beneficial for you to find out what is it exactly that you are not satisfied with and how you can improve on it. For all you know, your problem might not even be related to the lenses you use. A sweet spot can only be a guide and it means absolutely nothing if the aperture that gives you the sweetest spot is not the aperture you want to use for taking photos. Choosing the right aperture for your photos is more than just identifying the sweet spot.

The least of your worries is equipment nor a lens' 'sweet spot' at the moment.

Assuming no prior foundation nor experience, your best bet in improving in photography is the learn about LIGHT, then EXPOSURE and finally 'HOW A DSLR WORKS'.

I dont think sweet spots are the problems ....

Personally in order of importance ...
1. Exposure - ISO / shutter speed / aperture
2. How a dSLR works
3. Composition
4. Composition
5. Composition
6-10. Composition .....

Why not post some pictures and describe what you are not satisfied with ??? :D

Keep shooting !!!

a sweet spot's (or rather its size) is more important on the club-face of a golf club.

u'd probably shoot at all different apertures and compare 100% and see which appears sharper (but with the know how not to confuse shallow depth of field of large aperture vs deeper dof with smaller apertures ). But as many others mentioned, it is an exercise of futility when most of us shoot according to what aperture we need. Oftentimes, the widest available aperture might not be the technical optimum, but it might be what is necessary for the shot.

Usually 2 full-stops down from ur max aperture size. Shoot more and with practice it will be more of an instinct thing.. :)

The sweet spot... Is using the right aperture for the job :p

Its no use if you find out your lens' "sweet spot" is at f/8 and you insist on using it when when you should really be using for a particular shot is a larger aperture for a narrower depth of focus.

One of the fastest way to improve is to get critique on your photos which forumers here have plenty to dispense so start posting up and you'll see improvements fast.
