Opteka 6.5mm f/3.5 overview

  • 1Description

Offering a truly expansive 180° angle of view, the 6.5mm f/3.5 Circular Fisheye Lens from Opteka is designed for DX-format Nikon F-mount DSLRs, and provides a 9.75mm equivalent focal length. The unique fisheye design produces exaggerated, distorted perspectives, which can be creatively used in conjunction with the short 11.8" minimum focusing distance. One aspherical element is featured in the optical design to limit spherical aberrations and a multi-layer lens coating has been applied to lessen lens flare and ghosting. Additionally, a removable petal-shaped lens hood is also included for further flare reduction and protection to the front element.

This 6.5mm f/3.5 circular fisheye lens is designed for DX-format Nikon F-mount DSLRs, where it provides a 9.75mm equivalent focal length.
Extremely broad 180° angle of view produces an exaggerated perspective and creative distortion.
One aspherical element is utilized to reduce spherical aberrations and maintain consistent illumination and sharpness from edge to edge.
Removable petal-shaped lens hood and multi-layer lens coating reduces flare and ghosting for increased contrast and color fidelity when working in strong lighting conditions.
Manual focus design and a minimum focusing distance of 11.8" pairs with the expansive fisheye field of view for generating unique perspectives with immense depth of field.
Aluminum-alloy lens mount offers a rigid interface between the lens and camera.

    Opteka 6.5mm f/3.5 reviews

    6.5mm f/3.5 Circular Fisheye Lens for Nikon F is rated 4.6 out of 5 by 23.
    Rated 5 out of 5 by from Best Fish-Eye lens for someone on a budget! The lens is crisp sharp. The colors are very good. On a cropped sensor, 6.5 = 9.75mm approx but on a full frame sensor you will get a circular pic at 6.5mm. So I think, a partially Go-Proish distortion just adds glitter to the gold that this lens delivers. If you don't like that you can always correct that in Photoshop. It is a fully manual lens. Set your camera in manual mode and you are good to go. Set focus to infinity and f/8-f/11. Everything will be in focus crisp and sharp.� �I didn't find worthy to spend about 6X price of Opteka on sigma for not-much-different outcome. ...& mind you Opteka=Rokinon=Samyang. Choose the one you like.

    Rated 5 out of 5 by from Great value for the money I bought this lens for astrophotography on full framt'e sensor cameras - Nikon D800 and Sony A7. �I wanted the circular effect so I needed a detachable lens hood - this lens is designed for APC sensors but works on full frame sensors giving a circular effect with the lens hood detached. �I did some test shots just to get used to the lens and found good performance in terms of sharpness - some CA at the circular edge but not relevant for my use. �Fully manual but that's fine - you don't need autofocus with a fisheye lens. �Great value for a niche application lens.

    Rated 4 out of 5 by from At first I was not sure I made a good decision.. I bought this lens to take on a work / vacation near the beach. I have always thought fisheye photos were cool. B H photo has an awesome video about fisheyes with the photographer - I think his name is Gene Ho. Anyway..Igor the lens on sale and I thought it would be a great way to start. YouTube has a ton of videos on using it. It is totally manual. I have a Nikon d7200. Sometimes the light meter works and sometimes it doesn't - not sure on that. I have gotten some really cool photos- I set focus at infinity and keep aperture at 5.6. I do feel I need to look at the lcd to figure out what's going on. All and all I really like it. Totally worth the 120 for a fun photography outing!!

    Rated 5 out of 5 by from Great quality vs price Just great. I was looking for an eyefish for my Nikon 3200, and all lens were above 250 euros. This one, had a very nice price. how could it be 150 dollares? I went searching in internet, and got some nice feedback. I bought it in B&H, (nice store!!), and i am very happy. For the price you cannot have a better lens. Maybe above 250 (or more) you can have a better lens... but quality vs price... oh boy it is good. I had now over 50 shoots with it, and i like the results. It's a manual lens. The F is manual, the focus is manual, i can't use fash, but i am happy. Focus is a bit hard to learn on this lens. You move the focus ring and you can't see much difference, you have to test it a lot to lear how to use it, but for the price, yes it's good. Go for it!!

    Rated 5 out of 5 by from Value for money! I have bought this lens for landscape & astro. So far I have done landscapes, and I thoroughly enjoy this. Later this month I'll try it for astro. I am using it on Nikon D750 in Dx mode. Negligible but manageable chromatic aberrations.

    Rated 5 out of 5 by from Great! I'm new with fisheyes, but It's a fun lens, and I'm exploring ways to give one scene different looks

    Rated 5 out of 5 by from 6.5mm manual fisheye lens If you enjoy all manual operations you will love this lens I use it on my nikon D3200.

    Rated 5 out of 5 by from Border line Crazy! Run!! Don't walk!!! Need it!!!! Mine is sharp! Sharp as a tack! You don't think so, take a look at the bull in the glasses picture. Steady your hands if need be. ALL OF THESES PICTURES WERE TAKEN HAND HELD. Some I'm leaning against the glass. Tripod if it counts. I set distance ring to 2 feet because that is how far away I was from the glasses. For things farther than 10 feet away, set focus to infinity (as far out as it will go...10 feet) Set aperture� to 11, 16, or 22 for things 10 feet or farther away and 22 for landscape to get the majority of things in focus. Close focus you must follow your ring: 1.2 feet to 10 feet. Know the distance and set it. Things should be in focus. FULL MANUAL operation. Set shutter speed high enough to avoid blur if hand held. A complete dream to use. I do this professionally. I bought this to do close quarters like bathrooms for real estate sales. You must center things if you want art displayed to be semi proportionate and vertical. I certainly can get a lot more in the picture with this lens. Mine is tight, but fits snug on my d7200. The tulip lens hood needs to be on to have the lens cap(cover) fit right. Squeeze the rings on the lens cap(cover) and line one of those up with the WHITE DOT at the end of the lens and it will stay attached. Great idea to cut a circle sized piece of cloth to set over the lens when I put the lens cap(cover) on so not to scratch the lens head. This you can do. For this price, I don't have any problem doing that. I constantly use that cloth periodically throughout my shoots as the lens collects (attracts) dust or you will be spending far more time in photoshop than you had planned. Regardless, this lens has added a whole new dimension to my life. I love the fact that it is 6.5mm and not 8mm. I looked at pictures taken with them and I wanted MORE of a dramatic affect and I got one!!! Wouldn't get rid of it for anything! Sky's the limit here!!
