Nikon 300 - Hood Repair

->> Quick question for anyone who may have experienced this. I noticed that the hood for my 300 f2.8 was loose, even after tightening screw. I checked the hood and all the studs are intact. I put the hood on and tighten the screw completely but the hood is still loose. For the life of me I can't figure out what's missing.
Just wanted to see if anyone had any suggestions before I end up sending it in for repairs.
Thanks. |

->> you know, neither Nikon or Canon has come up with a decent way to hold those hoods on... and it is always an expensive fix. Next time one breaks, and it is only a matter of time, I'm just gonna go out and buy one of these:

I used to use a rubber plumbing gasket, but that is a problem getting on and off for travel etc. |

->> Steve WHICH 300??
One some hoods there is a small cup or bearing that is held on to the tightening screw with an even smaller (eyeglass) screw. If that cup or bearing has fallen off there will be too much play between the hood and the lens barrel even when tightened all the way.
I'll have to dig to find the mechanical drawings that Nikon sent me way back when. |

| ->> The hood could also be bent. If it is no longer perfectly round it will not fit correctly. |

| ->> Steve, Check what Eric mentioned. It also may be the Base Plate threads are striped. That is the piece the tightening screw theads into.It is a very simple fix to replace the Base Plate and tightening screw.Call Nikon Parts in El Segundo and order the parts. I just did this on a 400/2.8 AFS II and it takes about 15 minutes to do. |

| ->> IF you need a temp hood, use a CD case, cut off top end, with black gaffer tape all the way round, inside and out. Fits perfectly to a Nikon 300. |

->> I had the same issue with a Nikon 300 2.8 and ended up having to buy a new hood and they are not cheap. And why I never put the weight of the lens on the hood by resting the lens upright. Before they had screw-in front lens elements the adhesive of the front element would become loose from excessive exposure to heat build up by letting your long glass stand up right on ie. on pavement. Thus having that element pop out at any given time!
Unless perhaps you're a machinist you could probably fix it yourself unless its warped like Louis says. I could never fix mine. |

->> I bought a 400 two eight without the hood and I use what Joe uses, a heavy thick fifteen dollar plumbing gasket. It works great, but also makes shooting a challenging when it's windy.
Canon wanted over six hundred dollars for the hood, so the Aqua Tech hood is a great product compared to the real deal, but I think it's still over priced.

->> Call Nikon or better yet, your regional NPS rep and tell them you need the hood screw kit.
They will send you a full replacement set with small screws, the large screw and the little washer-like things.
It's a simple pop the old one out and put the new one in and life is good. I've replaced these lots of times.
If you call an NPS rep you will get it for free. If you have to have NPS send it to you it's probably pretty cheap. |

| ->> Thanks. I'll have to check out the "cup" as Eric suggested. The hood isn't bent, there are no studs missing, and the screw isn't stripped. Even with the screw tightened all the way down there's enough play in the hood for it to spin around and given the right angle, fall off. Seriously, how much engineering does it take to make a lens hood? That's definitely the one thing Canon did get right. |

| ->> I have heard so many complaints about people stripping the hood attachment screw. It seems the design Nikon is using now is pretty good and much better than what they have used in the past. I have no experience with Canon. I've fixed a few Nikon hood screws myself, it's not very difficult. The thing I noticed after using so many pool lenses is a lot of idiots crank that screw down to the point where it is almost impossible to remove, even when storing the lens with the hood inverted. It becomes a bad spiral: Dummy 1 cranks the screw down a few times, now the thing won't stay on unless you tweak the crap out of it so Dummies 2,3 and 4 have to over tighten it, now it needs to be cranked even tighter, then all of a sudden the screw is stripped and no one knows how it happened. After seeing that so many times I wanted to figure out a way to get the hood to stay tight without cranking the screw down like a retarded gorilla on steroids. I put a rubber band in the channel where the hood posts and retention screw connect to the lens on my personal 300 as soon as I took it out of the box. I've never had a problem with the hood not being tight enough and I've never had to turn into the Hulk to keep the thing on or remove it. "What do you do if something happens to the rubber band?" you ask. I put blue rubber bands on all my lenses as a way to identify them as mine, so I always have at least 3 spares if I'm out with the 300. I hope this little piece of preventative information helps. |

| ->> I had this same problem so I talked with a friend at NPS. I was told that there is a know problem with the threads stripping out. I ordered the replacement knurled knob and screws. It was simple to repair and I actually got two sets right from the start. A suggestion - use some lock tight or some nail polish to keep them snug. |

->> I don’t mean to resurrect an old thread but I was quite perplexed today when I ordered two new assemblies for my 400 f/2.8. Two new style base plates (old ones kept stripping as noted above), two new screws and two new thumb knobs for the screws ended up costing a grand total just shy of $200. It's amazing to me that the old screws don't fit into the new baseplates either.
I’m sorry but for six components that all fit together into two hoods I find that quite a bit excessive. |
