Chromatic Aberrations With Telephoto Lens Add-ons


 
 
I recently bought a Fuji S5200 with some attachments, such as lens filters, tripod, and lens attachments. The attachments mostly work well so far, except that the Opteka 2.2x telephoto lens not only decreases the image sharpness somewhat, but it also makes it very difficult for the camera to focus. What's worse, the lens creates horrible purple fringing. Is there any way to get around these problems or did I just get a bad lens?

Here are some pictures to illustrate my point.

P.S. I find I get higher quality pictures using my camera's 10x zoom and cropping than by using Opteka's 2.2x lens on top of my 10x optical zoom. I also find the the problems worsen when I use the 2.2x Opteka lens and use my in-camera optical zoom as opposed to using the 2.2x lens without using my camera's zoom.

  Another thing: I tried changing the camera's aperture, but that didn't seem to do much.

  I hate to be the bearer of bad news, Ariel, but I don't think there's anything you can do about chromatic aberrations. It's just a fact of life with some digital cameras and lenses.

  That's a shame. Well, thanks for letting me know. Would you or anyone else know of lenses I can get for the S5200 that have better quality? (I *think* 55 and 58 mm threaded lenses would work. I'm pretty sure that 55mm lens filters work with this camera and I have a 55mm to 58 mm converter. Would both lens sizes work?)

  Hi Ariel,
I have the 5200 and bought add on lenses too... Haven't really tried them much but seeing your pics I'm starting to think I won't bother. I think the in-camera 10x zoom does a great job and I guess I'll stick to that.
My add-ons were actually 52 mm even though the camera is 55...
Good luck!

  Diane, are you lenses from Opteka? Maybe you can try them and tell me if they are any good. Or maybe someone else can tell me if another company makes good lenses? Any more help would be great, because even though 10x zoom is really great, I may want more for some kinds of shots. I'd also like to hear about good wide-angle and close-up lenses, because the Opteka lenses are pretty good, but they're not great. Thanks again!

  Ariel, I have the same problem with my Tamron 70-300 zoom and found a procedure for removing it from the photos. It works really well. It is an 8 step process but very quick and easy.

If you have any problem accessing the link, let me know and I will scan the info (I printed it out) and email it to you.

Thanks, Mike. I was able to see the link, and I appreciate it. But that is only for removing purple fringing in photoshop, right? That wouldn't really solve my problem. The lens also makes things very blurry. Let alone the fact that I don't have photoshop! So I appreciate it, but if anyone else has any other ideas or knows of a better lens, please let me know. Thanks!

  You are adding on an external lens element that was not anticipated when the camera's lens was originally designed. There's no way that you'll get the same quality out of it as you would a purpose-built lens.

You can't make a silk purse out of a sow's ear. Enjoy your camera and its lens, and use it as it was intended. If you want more flexibility/capability with good quality, then you'll have to buy a dSLR.

  A dSLR?! I was afraid of that. Well, thanks anyway. I don't think I'm ready for one yet. The wide-angle lens is pretty good, and the camera's 10x zoom is also great. I guess I better return this 2.2x lens, but if ANYONE knows of a good telephoto lens I could get for this camera (for less than $100), please let me know.
Hasta luego.

  Hey Mike, I was just going through this old thread because of another thread I responded to. I checked your link again (this time knowing what the terms mean), and I realized that you can do this much more easily in the Aberrations tab in Helicon Filter.

  Thanks Ariel, I will need to consider getting it for the occasion that I get some CA in a shot.
