Can you not adjust the aperture? Is it always f/2.8? Thanks.

I haven't owned this lens for very long but I've had very good results with it so far. I mainly shoot with automatic settings and the camera adjusts the aperture for each picture of course. It is not always on f/2.8. It varies, depending on the light conditions, etc. if you shoot manually you can keep it on f/2.8 if you want. That is simply the largest aperture setting you can use on this lens. You CAN change it to a smaller aperture if you want.

Of course...2.8 is merely its widest aperature. Goes all the way to F22!:-)

Yes you can adjust the aperture... It goes from f/2.8 to f/22. It's a great piece of glass!

Yes you can adjust the aperture. F/2.8 is the max you can go and it can be constant as you zoom in and out. but you can lower it to say F/8 etc.

Widest aperure is 2.8 but you can go up to F22 depending on your need and composition style.

No, you cannot. F/2.8 is only available for objects that are far enough. For the closest objects (0.38m) it will be F/5.6.

OK it's just a lens and it's fixed at f:8 so unless you're shooting at a very high ISO it's not going to work in low light. Also it's not the clearest lens in the world....

No, the aperture is not locked in other shooting modes. The aperture ring may stay on the f/2.8 position, but the actual aperture will vary according to other settings such as shutter speed and ISO, and the lighting conditions. Try aiming at a bright subject and look for the aperture value that appears on the camera's display.

I am not sure if you are asking how low can you go as in is there lower then 1.8, BUT aperture can go as low as 1.2 which is EXPENSIVE. 1.8 is just fine if you are thinking cost effectiveness.

No, you can,t adjuste it. In fact you will see the photos with the circle frame of the lens with the complete zoom out.

sorry don't rember ever having that problem ?? but i'll look in the manual tomorrow!! doyou have a correct lens on?

The camera controls the aperture, set it at f22 and forget it. Beside why would you not want the camera to control the aperture. If you switch to A or M mode you can set it to whatever stop you need and the camera will close the aperture down to that setting when the shutter is pressed. On some very old nikon cameras you needed to use the apertue ring and set it at the aperture you wanted, but if you where shooting something at f16, the viewfinder was almost black.

Hi Beth, yes, you can change the aperture settings as well as the shutter speed, ISO level and exposure compensation in Manual mode. Thanks_Mitch

It is not hard to use at all. Either with focus-peaking or magnified focus. Besides, it has great depth of field and if you close down to f 8 everything is in focus from a few feet to infinity.As far as aperture, you just adjust diaphragm looking at the meter and will see when it is right in the viewfinder.

Specially, auto focus doesn't work. Always I have to set to f4.5-5.8, otherwise camera doesn't work. It is shOt lens.

The biggest aperture for this is F3.5, which is not that big. But it does give some bokeh effect. Whether it meets your definition of shallow DoF depends on you I guess. U might want to hunt around the web for sample photos?

My answer to this is to set the lens at F8 either with Aperture Priority or Manual Mode. Having the lens wide open at F 4.5 just doesn't give the best results IMO. The results of learning this lesson is in the early results of seeing soft images at the edges of the pictures and loss of sharpness. F8 makes all the difference with this lens at least for me.

This doesn't have adjustable aperture blades. thus the aperture is at max. OM lenses themselves have on-lens adjustable aperture.

You could probably change the ISO/shutter/aperture settings to compensate for low lighting, but I usually set it to Auto mode, and I feel it's not bad. I can still see relatively well although it's rather noisy/fuzzy (it hardly bothers me, but I usually try to avoid low lighting anyways).

I had heard about the focus problems but we have had no problems with it what so ever. At wide open apertures, the depth of field is extremely tight, so I am guessing that some people who have less photographic experience were the ones complaining, because even at those apertures we are producing tack sharp images, on auto-focus or in manual on our Canon cameras, a T5i and a 60D. Sigma has released an updated version of the 50mm in their new "Art" lineup, so if you still have concerns, save up for that one. I've played with it at our local camera store and it is beautiful!

It is not a "fixed" F/2.8. It is a "constant" F/2.8 which does not change when zoom from 24 to 70. It still has the smallest aperture of F/22 that you can use to gain all the DOF you want.
