Inspecting Vintage Lenses


what’s up everybody today we’re going to
be inspecting lenses to make sure we get the best bang for our buck ok just like any other used item lenses
come in all different kinds of condition and today i want to go over a few things
that you can look for when you’re out buying lenses to make sure you don’t get
stuck with a lemon now a lot of you guys know I buy a lot
of my lenses from the thrift store and some of the things that I look for I
look for those front and rear caps and a UV filter too if it’s got a UV filter
and those caps that’s a really good sign that the owner was taking care of the
lens at least enough to have the caps and a UV filter i never go shopping
without my phone i bring my phone for both to check use prices and because
it’s my flashlight now after getting that initial look if it’s still
something that you’re interested in buying your gonna want to get your hands
on it and you’re gonna want to test out that focusing ring take it through its
entire range make sure there’s no sticking points and it’s not gritty and
also test out the aperture ring make sure there’s no skipping going on and
you want to see those blades open and close now some mounts won’t allow you
to do this the canon FD mount requires the lens to be mounted to the camera for
the blades to open and close so if you’re out looking for FD lenses you’re
going to want to have either an adapter or a camera that you can mount that to open and close the blades ok now i want to look at some of the
common issues some of these lenses have and they’re not always apparent from
afar you’re gonna have to get closer and
you’re gonna have to have a light with you so always go shopping with a
flashlight now this canon FD lens looks pretty good
from this range but when we go in a little bit closer you’ll notice that
this one has been infected with fungus and this fungus is on the front element
but it can be anywhere in the lens and it doesn’t always look the same this one
looks kind of like a spiderweb but it’s definitely something you’ll need a
flashlight for your gonna want to keep an eye out for now this next lens i
bought off of ebay it’s the Yashica 135 2.8 and the seller had described as
perfect and then I got it home and took a closer look at it was loaded with
Haze and how he’s affects your picture is it just makes it look really cloudy
you lose the detail here’s a quick side-by-side comparison
now almost all these lenses suffering from some sort of internal dust and I’ve
got these two konica 40 1.8 one of them is clean one of them is really dirty and dusty on
the inside and here’s a shot of the clean one and then here’s a shot of the
dirty one just something you want to keep an eye out ror. Now like i said earlier
gonna want to make sure those aperture blades open and close and this is the
reason they can have oil all over them that can make them stick this lens was
initially stuck wide open and I eventually got it to close down and I
saw boil all over these blades now I looked at some of the common problems
these lenses have but there’s all sorts of other issues that can come up and I
would say just be smart take your flashlight take some way to compare use
prices to make sure you can’t get that lens cheaper online in better condition
and that always like to leave it was a little betta fish bokeh unfortunately

  1. Great info and images there. Well done. Do you know what haze is? I haven't run into that one yet. I just figured it was a form of fungus.

  2. Great video! Very useful information I did not know about.
    Is there a way to fix any of those issues or is a lens in that condition unusable?
    Thanks for sharing

  3. Another great video. Dust should be the least of a used buyers' worry, that is unless there is so much that the veil of dust is visible in bright (not flashlight) light.

  4. Adapted Alpha , dont you have an official facebook page to follow, and a newyear wish for2017, please let us see you shopping in a thrift store, not to learn about its name and location. just to follow your shopping and hunting down an item, in my city i hardly can find anything at all, not even bad copies…im curios to see the amount and varialtions of vintage lenses to pick from,,,, and please keep them videos coming, the are my favorites

  5. Thanks for this and other great videos! I'm just getting into trying vintage lens on my a6000, so thanks again for having videos of many of the lenses I want to try!

  6. For the canon fd use a key to push the little pin on back side and move the switch to the L position so that you can control the aperture manually

  7. Hey man, recently i just bought SMC takumar 50mm f1.7, and im confused with the adapter i Will be using, i know its Pentax to Nikon, but There is to type adapter that has very difference prices, one that can do infinity focus, and the other does not, the price differences ia almost 20 Bucks, so i want to ask which Will be better for street photography?

  8. Can you do a tutorial of how to clean them? i mean if you find a very good deal and we can clean it ourselves maybe its worth it
