New lenses - pickup evaluation tips

Just arranged to meet up to get the below camera/lenses for $300CAD.

Thanks,

Look for sticky aperture blades, Scratches on the glass, particularly in the rear, Smooth focus ring and zoom ring movement. No haze or fungus on the glass and no oil on the aperture blades.
Bring a camera to test each lens. There's a couple of nice lenses there.
What's the asking price?

That's a very reasonable price if the lenses are in good condition. Take a magnifying glass with you to look inside the lenses for haze, fungus and oil. Make sure you 'flick' the aperture lever a few times to see that the apertures open and close faster than the eye blinks. Sluggish or slow blades are a sign of issues.

Check the rear for dirt and grime around the electrical contacts. Not a big deal but any corrosion could be. A little dust inside the lens is not an issue and normal.

If they look good and test well on your camera, buy the lot.
The 50mm and the 400mm are both nice. The 70-200mm is far to good. The 28-80 is average at best. The 50mm is worth close to $200 as a resale lens by itself. The 400 is around the same.

Oh and a couple other things. Bring a small fashlight to check inside the lenses.
Make sure you bring a digital camera with you to test each lens for auto focus and exposure.

The 70-200mm is far to good.... meaning it's a good lense? I would have thought it's average like the 28-80 since it's a common lense.

Sorry Typo "Fair to Good" better than the 28-80mm IMO

But you can get good use out of all of them.

Thanks again. My only AF lense is the Sigma 17-70 2.8-4.5. I have some other manual focus primes, 50 1.8, 28 2.8, 200 3.5 (crap), and the Pentax-A 35-105 3.5, so this set will fill most of the gaps.

Any guesses as to what's on the front of the 70-200?

Yep, that's the lens, Pentax-F aka Takumar-F (sometimes different labeling). The thing on the front might be some kind of hood. One person on DPR liked the 28-80 quite a bit.

The 50/1.7 is excellent and sharper than the 1.4.

What 200/3.5 do you have that is crap? I have a Vivitar Komine (serial no. starts with 28) that I quite like.

Looks like a rubber pull out hood (collapsed) that is screwed on the front.

The name on the 200mm escapes me. I use it, because it's all I have, but it renders reds horribly and flat pictures. I couldn't find anything on the interwebs about it when I got it, it's a screwmount, I think I found out that they were made for department stores in Montreal or some such thing. It was free, so I didn't complain .

Thanks for the feedback, I'm excited, new toys!!

Good call on the hood, looks like it to me. I'm also in need of a camera bag (currently using a small cooler), so I'm wondering what 'carry case' and 'more stuff' means.

Not getting much work done this aft

Since these are F lenses, also look to see if the plastic next and below the glass distance scale window is properly attached, apparently it sometimes come of.

The F50 f1,7 is amazing, I'm not too sure about the rest, but a 70-200 should be a good lens, I'd think.

Enjoy your new lenses.

Don't you just love it when you snag a deal like this? The extra Sigma lens is Pentax K mount? Is it an older manual focus lens?

I might be interested in the coloured plastic (gels). Care to post some pics of it and the sizes.
