Aloha, please pardon my ignorance, will you tell me which lens would give a sharper picture. (1) kit lens EFS 18-55 1.35-5.6 IS 11 or EF 28-80 1.35-5.6? both are wide but the 28-80 I think is better for portraits. What are your thoughts? God bless Ed

It depends on how you plan on using them. What are going to be photographing?

anything and everything not far away. I tried the Blood moon the other night! Sunday I will photograph a 55th wedding anniversary party.

so neither would be sharper than the other
I'm sorry that I didn't address that question. I believe the 28-80 would produce sharper images if you hold the camera steady.

Ed, if any of the party is indoors, it's not gonna matter which lens you use, but you are going to desperately need to use flash!! ;-)

Because if you shoot a party between f5.6 to f8 (most lenses "sweet spots" when it comes to sharpness ), you'll get better exposures and faster shutter speeds in better light, typically to be had outdoors. If not, use a flash for sure, and you'll be glad you did. And by the way, the 28-80 might be sharper on a crop-sensor body. :thumbup: :-D

Also an external flash will give you superior results than a camera's internal flash.

What? Why would the sharpness of a lens be dependent on the subject?

If you do not use a flash in that environment, you will need to increase ISO and slow down your shutter speed to capture enough light for a useable shot. That will affect sharpness. Using a flash you can have a much faster shutter speed, freeze the action and reduce blur caused by vibration.

If a subject is stationary (like with a landscape), you can use a longer shutter speed and a smaller aperture. This gives you 1) more light with no motion while the shutter is open and 2) a greater depth of field, meaning that your subject is more likely to be in focus. If the subject is moving (like at a party), you need a faster shutter speed or subject motion will cause blur, you may also use a larger aperture to get more light, but the depth of field will be more shallow and your subject less likely to be in focus depending on your ability to either manually focus or to target your subject with auto focus.

Back to your question. If you are on a cropped sensor, the 18-55 will probably be better at a party, since you can get to a wider angle for the indoor shots, if you are on a full frame the 28-80 will be Ok indoors, but given the lenses you put forth, my guess is that you are on a cropped sensor. The 28-80 would be better for the moon since you can zoom a lot further. Neither lens is “great” optically, and wide open use (at 3.5 ) should probably be avoided since neither lens is very good wide open. You might want to stay above 4. Indoors you might want to shoot the 18-55 no shorter than 20mm and the 28-80 no shorter than 30. For the moon pull the 28-80 in a bit (maybe 70ish instead of 80) since the quality reportedly drops off at the long end.
