Do these lenses have adjustable f-stops, and automated exposure control?

It was a OK camera, however the E500 is a better one. I upgraded my to E510 the semi-professional and still have it and have not changed it for the purposes. However, if you want a beginners SLR then get the E300.

I am not sure. When I use these filters I use manual focus. I am usually stacking these or combining them with an extension tube or two so I will set up the subject and move the camera back and forth to focus and then use manual focus to fine tune the image. The extension tubes disconnect the mechanism of the lens so no autofocus is available. Putting these filters on is similar to using a polar or UV filter. The mechanical connection is not affected. These will open up a new world of photography for you. Have fun.

No auto focus control, even if you're using lenses with AF. (At least for the canon lens mount, though I expect all the mounts are like this). Also, iris/exposure control is limited on some lenses. Check their website to see what works.

These tubes have no internal adjustments or circuitry or anything like that. Once you put them on you have to set the camera to be completely manual, both mode and focus. I use these on a D100 and it fusses about settings until I set everything on manual and then it works.

Yes it does. There is a tab for manual or automatic focus. Also, when the lens auto focuses you can rotate the dial and alter the focus point.

I also took a good look at the controls, and see no evidence of aperture/f-stop controls. As has been mentioned by others, you can adjust ISO and EV. If your goal is to change the depth of field, that's not very useful. The only options I can think of are to try the Background Defocus mode, or use software after the fact to change your depth of field. I don't currently have Photoshop, but I'd imagine it does a fine job of defocus. I do sometimes use Pixlr Express on Android. It does a nice job with background blur, very adjustable. Good luck!

Yes there is a AE-L/AF-L button you can access with your thumb. It has two wheels to change you F-stop and shutter speeds too.

Yes of course! You just may need to convert (mentally) from T stops to F stops. Buy from OpticsDeals!

You can manually adjust the aperture or allow the camera to set the f stop. As far as auto focus the lens does have a motor

Yes. There is an adjustment next to the viewfinder that allows for fine tuning of the focus.

Hello Kathryn, yes this extension tube supports automatic features. focus and aperture can be controlled through the camera.

no, but changing your F-stop will give you the vignette effect. These rings are a really useful tool for closeups and macro/micro photography.

Yes it does. That is the purpose of the 1.4 f-stop to let in the maximum amount of light. When shooting in a low light situation where flash is not an option this is the lens of choice.

Yes. The "M" setting on the dial allows you to set ISO, aperture, shutter, etc. manually.

Yep. Manual aperture and focus. Some vignetting and hard to correct distortion but performs great for the price. The 16mm is designed for smaller sensors but the 14mm is the one you want.

No, the lenses are not motorized and must be manually turned for the proper focus.

No, aperture is controlled manually. FD lens cannot be controlled automatically.
