What do you mean?
shutter speed of 125 ish does not guarantee anything except that the shutter will fire off at a speed of 1/125th of a second. ;-)
he means shooting wide open on primes can still give you sharp images.
almost a must at some weddings as the lighting is terrible.
Thank you. I think my biggest problem is the lack of practice. I'm in school, but honestly I don't know if the teachers are all on the same page, but when I ask them questions they either say one thing or another, never an accurate yes or no. I guess they want me to figure it by actually practicing and using my gear.
I thought I had all my technical aspect covered, but we learn as we go.
Posting an image at 800 pixels wide is not a ood way to find focus issues.
Post either a full resolution image somewhere with a link to it or post a 100% crop.
AND post the EXIF
Just gotta shoot and practice as ya said. Only way to get better. If it were simply to do what teacher A said...then you succeed...everyone would do it. Take the learned stuff, mix with the practice and 5K shots later ya might get it figured out. lol. shoot shoot shoot....apply different techniques and settings...and you'll learn more than any teacher can tell you.
get a tripod
set your camera apereture priority f22 (or as small as your lens will go)
set your camera on timer delay so theres no vibration from shutter press
set your camera on mirror up so theres no
set iso to 100 or 200
use manually focus to
now take a picture of a row of beer bottles or something you can stand in a long line. shoot down the line and manually focus in the middle
now do the same for all apertures back to f1.4 in 1 ev stops
check your photos. youll now see quite clearly how sharp the lens can be at what apereture
youll have no
vibrations to interfere
btw i do this whenever i get a new lens to play with
and/or try using autofocus on a discrete item halfway down the row and see if the camera is focusing correctly.
Af-a has nothing to do with the focus points though - that was my point. Af-a switches between af-s or af-c. You can set the camera to af-s but you still have to choose single-point AF or auto-area af. So af-s isn't necessarily synonymous with single point focus.
The shutter speed is fairly decent but with a shallow depth of field (like you get using wide open apertures) the slightest movements can throw off the focus. So many people have issues with blurry/out of focus shots when they get their first fast prime lens. Being able to get a sharp in focus shot with wide open apertures is a skill so it takes some practice.
You do know we are and have been saying the same thing right? I am well aware of what af-a and af-c etc do. You missed my point in how I think of things as they relate to each other, and at this point it really doesn't matter. AF-S is easier to type that Single Point AF. As I said, I relate them to be used in conjunction as using AF-A really is silly to me anyway...and using Multi-Point AF is on AF-S is silly to me...so I'll agree to a newb who can't read my mind, I might have confused them. To everyone else..I'm sure they understood my meaning, however you are the only one who decided to try to educate me on what I already know. thanks.
I guess to avoid silly rebuttle of saying the same things with different verbiage I will spell out everything should I chose to reply to a post.
You mean an EXPERIENCED photographer, that has experience and knowledge in HOW TO shoot wide open???? Stop obfuscating the issue!
