Raynox HDP-2800ES High Definition 0.28x Diagonal Fisheye Conversion Lens

I purchased this lens to use with my Konica Minolta Z2, which takes 52mm accessories. The lens comes with 37mm & 43mm adapters. The lens has 52mm threads, but according to Raynox, can’t be used on cameras with 52mm filter threads without their plastic Raynox RA5252B spacer adapter (sold separately & which I couldn’t find). I called Raynox customer service and they found me a metal Fotodiox 52-52mm spacer adapter on Amazon which works fine. The specs say that to give full frame results the lens must be used on a camera with 26mm equivalent focal length. My Z2 is only 38mm. I ordered it because my friend's older model HDP-2800E produced full frame results with my camera. It only had one very small vignette on the top right corner because my sensor is not perfectly centered.The newer model is sharper, but with the spacer has more vignetting with my camera. I cropped the vignetting off. I only had to crop off 13.5% of the pixels so still got good quality. My old Z1 was 3.2MP. My Z2 is 4 MP & is 3.35MP after cropping.I discovered that I do not need to use the spacer with my camera and that without it the lens is full frame, covering about 160 degrees, almost the same coverage as my Tokina fisheye for my Canon 70D DSLR has when it is cropped to the 4/3rd format that the Z2 has). Enlargements from my Canon 70D require heavy cropping to fit the paper because the sensor is so rectangular. Enlargements from the Z2s 4/3rd format sensor don't, so the coverage is almost identical for enlargements. The Z3 & later models have a wider lens than my Z2 has, so on them coverage would be virtually identical for enlargements, pretty good for a conversion lens.Often there is sky in the top right corner, which is easy to clone out. I clone it out and the image ends up completely full frame. The edges & corners improved greatly without the spacer. It had chromatic aberration in the corners & edges in some shots, with the spacer installed. This lens is a nice addition to my other lenses for my Z2. The lens is very well made. My only issue is that the supplied rear cap only fits onto their 37mm adapter ring. If you use another size adapter ring you have to replace it with the 37mm adapter to put the rear cap on. Since my camera uses 52mm accessories, I removed the 37mm adapter & rear cap and I use the bottom part of a 52mm stack cap set as a rear cap. If they had supplied a 52mm cap it could be used with any camera. You would just have to remove whatever adapter you use and cap the lens with the 52mm cap since the lens itself has 52mm threads. If you have a camera that takes 37mm accessories, what they supply is great, just leave the 37mm adapter on all the time & cap it with the cap they supply. Not so great if you use a different size accessory ring. I am including pictures I took with this lens & my Z2 after cropping to remove the vignetting. For one picture I added an additional picture after I removed the barrel distortion. The snow picture was taken without the spacer, after I discovered it was not needed. It gives you a good idea of what this lens can do at full frame.

This is great for those shot you need to get all the action in a tight spot like the Drummer in a rock Band. Very nice lens. No Fuzzy edges just clear clean and very wide. Make it look funny by putting it up to your face. It is the missing shot you always need for s Music Video. Get creative and have the option to show your talents. Works perfect without an adapter on the Sony AX-33 4K UHD video Camera....

Good Procuct
