Stiff focus may be relieved by adding a tiny drop of Nyoil to the helicoid with an insulin syringe and working it in very well. If necessary add a second and work it in very well. Do NOT over do it!

I learned this from a camera repairman friend.

Hi,

the 25-50mm is too big for my taste. there was one being sold really cheap yesterday, i was tempted but I skipped.

The 25-50mm is larger but it really is a serious lens, another class completely in terms of sharpness and APO-like lack of CA

A few walk around from the 28-50 - mainly snapshots around Vancouver

             That's why I am staying with Tamron 20-40 - flared, too, but AF is dead-end, with better contrast/color ratio, than any of them above. So far I am OK, but, if any needs, I'll go for the new Tamron 15-30. Good luck!  LZ

the pictures look more than acceptable for what i intend to use it for :o :o :o

be careful with injecting stuff into the helicoids as this will react with the grease and there is a huge likelihood that the grease will harden after a period of time.  ::)
these lenses end up cheap on yahoo auctions and find their way to my collection ::)

the 20-40 tamron is legendary.

So there is a 28-50, a 25-50, and a 28-45??

All of them exist.

The first wide-angle zoom was the 28-45/4.5, later to be refined as the 25-50/4. The 28-50/3.5 is the youngest of them, made to provide a cheaper and smaller alternative.

Richard,

I'll toss out the AF 28-70/3.5-4.5D Nikkor as an alternative to the original lens in question. It has one hybrid aspheric element. It's quite well made as compared to many AF lenses. It has quite reasonable flare and ghost for it's era with 8 elements in 7 groups. It's decent wide open and very nice one stop down. It's small and unobtrusive. I use it with a Nikon HN-3 hood and no filter for protection. I use a Tupperware #G tumbler cap on the HN-3.  I own two of them. The first cost $84.00 USD from KEH.com.

Best,

Dave

I own a 25-50/4.0 AIS and like the lens very much. The only down side is the 90 degree throw on the focus ring. The 25-50/4.0 AI has the same short throw which makes manual focusing more difficult.

My previous film-era wide-angle zooms were the manual focus 25-50mm f/4 and the autofocus 20-35 f/2.8.  The former was a joy to use with film but is quite large and heavy.  The latter is better as an autofocus lens, and it's quite poor in the outer reaches of a photo when shot at f/2.8.

While I've been using only digital for the past 5 years, I've kept my old film cameras and lenses and I still expect to use them once in a while.  While I haven't actually done this yet ::), I went ahead and bought a copy of the Nikkor 28-50 f/3.5 for its small size and decent photographic quality, with the expectation that it could be a reasonable walkabout lens.  I could always throw in my Series E 100mm f/2.8 for a very small and lightweight kit.

I went ahead and did some casual test shots - nothing rigorous, all handheld.  I didn't alter colors or saturation directly, but revised exposure, contrast, and highlights as needed to avoid or minimize clipping.  All photos are modestly sharpened.  As always, any negative results may be due to sample variation or user error. 

I found infinity to be quite soft, especially at the wide end.  I'll have to return to that with a tripod and live view and see what I can find out.  This might be sample variation or even wear and tear; my copy has the stiff zoom action others have mentioned.  F/3.5 is not that sharp, but then these were handheld shots on a D7200, with focusing done via the focus dot.  Your results may vary.  One of these days I need to get a Df or Df2.  ;)

Flowers in macro mode.  These flowers always give me fits as the red channel blows out so massively it's hard to fix without serious underexposure.  So please tolerate my processing in which I tried to tame the raging histogram.

Nice!
I saw a sample and it was as sharp as I wanted wide-open. unfortunately, I wasnt in the mood to throw ¥7,500 away for that at that moment. I may get back to it as I recognise that it is an exceptional copy despite the dusts inside. Ric.

Quite a nice little lens if you can live with the limited zoom range - I tend to think of it as a flexible 35!
Just don't point it into the sun - lots of coloured blobs all over your image!
