  • Note: Manual Focus/MFPlease note: This is a manual focus lens (no autofocus/no AF)". MUST need to "Set to camera mode to M (Manual)" for use, otherwise it will show the "Lens not attached" error (it will not allow you to press to shutter when in error page". More important, manual lens MUST need to manual turn the "focus ring" on the lens to achieve focus.

  • Upgraded versionUpgraded into an F mount, which can be mounted on Nikon DSLR cameras without connecting the T adapter ring. For those who photograph wildlife or the moon as a hobby, this lens would be a great choice;
  • F Mount CompatibilityCompatible with Nikon D-series DSLR cameras: D850 D810 D810A D800 D800E D780 D750 D700 D610 D600 D500 D300 D300S D200 | D7500 D7200 D7100 D7000 D5600 D5500 D5300 D5200 D5100 D5000 D3500 D3400 D3300 D3200 D3100 D3000 | D100 D90 D80 D70 D70S D60 D50 D40X D40 | D6 D5 D4S D4 D3S D3X D3 D2XS D2X D2H D1X D1H D1;
  • NO electronic contacts and No Autofocus MotorManual lenses lack electronic contacts, so you need to use our lens in Mode M. In the meantime, you must set the ISO/Shutter speed in mode M, otherwise the photo will come out too Bright/Black. On manual lenses, the camera may display F-- because it doesn't have direct access to the aperture value.

This item did not work with my Nikkon D3300. Im not sure why? The package looks like it's from 2000. It was taped closed with scotch tape. There is no doubt this item is used.

    • 4 stars at $54 and understanding what it is
Style: For Nikon F (D-series)
For what it is, a fun lens, it is 4 stars. On an absolute scale is is 1 start. Fringing is awful (that purple you see), hard to use, low quality all around. Pointless tripod mount (it is so light compared to the camera). Terrible bag. But if you have something that'll correct the pictures, patience, an appreciation for fun but low quality lenses, maybe a 100,000 ND filter on a 77mm adapter, you could get sun pictures showing sunspots. Sure I got 1 out of 10 initially of everything I tried, but it was a good test of my tripod. It does help to have a camera with a viewscreen (D750). It is mostly metal and glass. Knowing what to expect going in, and having the tools (tripod, software, sunny day, patient spouse, ND filter (no longer in 77mm, https://www.amazon.com/dp/B0CX1NPSRM, surprisingly good), I'm pretty happy. I could even hand hold (without the neutral density filter of course) and once in a great while get a mostly focused picture of dogs (very thin band in focus, not super sharp, but fun). Will it replace my lovely 70-200 f/4? No way. Will I still get a 150-600 or 150-500 some day? Surely. But those are north of 4 figures and this was $53.60. So 4 stars. ... show more

I was willing to give this lens a shot. Yes, it’s low end and manual focus and slow as a turtle - but I was able to overlook all that. The build quality is okay-ish for the price. The image has (as expected) chromatic aberration. Where it all falls apart, though, is the super cheap and flimsy mount ring that they put on it. It is absolutely terrible. Want to frame a shot on a tripod? Go for it - and then your frame is completely different once the weight of the camera makes the plastic bend. Need to focus? Good luck! You can’t even turn the ring without the picture jumping around wildly. If it had a better (dare I even say metal) mount ring the experience would be loads better - but as is with the one it comes with it’s frustrating at best. I left two stars because I was able to pull some semi-ok pics handheld (with the requisite lack of stellar focus that handheld will get you). The attached photos are using it that way. On a tripod, though, it’s pretty much an exercise in futility. I didn’t even bother including those. ... show more

    • Budget friendly zoom shots, get what you pay for
Style: For Nikon F (D-series)
meh, its okay, pretty grainy photos unless you get pretty close which kind of defeats the purpose. Kind of has a hazy look to it which looks kind of cool sometimes. But its not really desireable. Okay but I usually leave it at home now unless going for gators. also i'm amateur at best, so others might get better photos out of it ... show more

This product is the most budget AND we'll made tele lens. DO NOT BUY IF... 1. You dont know how to manually adjust shutter speed and iso on your camera, because the aperture is tied directly into how far your zooming and it will not work on camera AUTOMATIC modes. But I have snapped some beatifull pictures with it. ... show more
