Looking through the regular lens, everything seems unclear, ie out of focus. Is that because of the curve of the lens? The bifocal part is fine.

Belinda, I use these in a manufacturing environment and have had no issues with blurring. The main part of the safety glasses are just ANSI spec safety plastic. The only lens part is the bifocal. If you are seeing blurry you may need prescription safety glasses?

The depth of field for focus on this lens is quite short. You need to put on the lens and then focus by hand.

Maybe due to focal length they are classifying it as fixed zoom but I would disregard. Focal length is equivalent to 45mm on FX.

Hey Aaron, common mistake. What you need to do is set the actual aperture on the lens ring to 22 and the lock it on that value so that the little red line aligns with the 22. This happens because you are using an older non focusing lens on a newer body. Problem solved. Have fun, that is a fantastic lens.

Like the rest of the comments, you are right, it will become a 48mm lens, pretty close to what you see is what you get through the viewer. I did notice the lens it has a unique sound when it is focusing. it is pretty cool. I been using this lens for a while now, and it took me a little to get use to it. (I normally shoot with a 18- 200 zoom) so moving forward and backward to get the shot took some getting use to.

I assume you've tried auto focus at different legnths. If unsuccessful you definitely need to return the lens. Sorry to hear about your troubles.

Hello Patty, Honestly I dont know. It might have to do with the total focal lenght, I ran into a problem with attaching a reducer then the diagonal then the bifocal then the eyepiece, and i could not focus properly. You best bet is to call Celestron on Monday, sorry I could not help more, Jim

It's a great lens if you can get it to work without any issues. Please make sure that the lens focuses currently.

The image should not be blurry. Have you checked to make sure there is nothing on the viewfinder area...there is a red dial that can change the focus but i wouldn't think it would be blurry even if that was off slightly.

Parallax is not adjustable so depending on the target distance, the focus may be a little fuzzy.

you have focal/focus point,which is what it says.depth of focus is what you can use for average focal/focus. too little makes it hard to stay in focus,too much is all blur.

It is a noisy lens, but so is the 50mm f/1.4. When back focusing it sounds a bit like a small electric toy car (it doesn't have an ring ultrasonic motor) and when locking focus there is a small click like sound. That's perfectly normal.

When we first got ours we had the same problem with clarity and had searched all through the menu options with the blurry image trying to find it. The plastic part around the lens is what you use to focus the image. The first time it felt like that wouldn't move but if you keep at it gently it will work and then you won't have any problems moving forward. Once you fix the clarity you can read the menu better to adjust the image size. Good luck.

It's probably going to be an alignment issue. You need to be sure the chip is perfectly centered over the eye. Make sure there isn't any dust or dirt on the lens or chip itself.

You will need to find the sweet spot for straight lines (by tilting) in your composition. Sounds like your Sigma worked the same way.Fisheyes are like that :)

I suppose it has nothing to do with the cameras and all to do with that particular lens. For the price of the 50mm 1.4G plus it being a prime lens I figured it would focus super quick. It's funny that you bring up the 35mm 2.0 D lens having problems. I own that lens also and mine focuses just fine and much faster than the 50mm 1.4G. I'd love to hear what you find out from Nikon about this problem.
