Question about Chinon lens

[alelinuxbsd]

I would like known if is a good productor and if their lens are equiparable to Pentax.
Eventually you could said wich lens avoid and wich lens are good.

Also I would like known if Chinon lens are good regarding flare.

Thanks.

Some of the fixed focal lengths are very good indeed, although they seem to me not so well made as Pentax lenses - and usually larger in size for similar types. In UK at least they are still not expensive to buy.

Which version of 135 mm do you have?

Could you post some significant shoot at maximum aperture?

How to behave towards the flare?

[martinsmith99]

I have the 200mm F3.5 which is very good at F5.6 and smaller. Not bad wide open. I found it to be sharper than the 200mm S-M-C Tak with better saturation and no problems with CA or flare. The 200mm 3.3 is a stinker though so avoid!

There are multiple versions of chinon lenses. Auto chinons are single coated. I have a set myself: http://www.flickr.com/photos/10403737@N03/3761447285/
These are nice lenses. I find their build quality to be only slightly less than pentax aside from chinon's weaker aperture mechanism. As far as flare, they have never really presented a problem. I'm a bit obsessive over proper hoods however. So there is always one on my lenses.

There are multi-coated versions as well. They are marked as such. It is probably hard to say who would win in a flare-off but most likely a S-M-C or SMC pentax would take the cake. I can't really comment on their quality. Above average would be my guess.

Maybe my mistake as well. I assumed the post was asking about m42. But maybe K? Most of chinon's lenses were adapted to both. Some were not, like the pancake. They should be identical otherwise though.

[alelinuxbsd]

For the moment I see K bayonet, however perhaps i think len are the same.

[themoleman342]

I don't have any pictures in my profile from the chinons.

In M42 mount I found the 28mm soft at the edges and the 135mm very good, although prone to a bit of CA.

[alelinuxbsd]

Is the CA simple to correct on postwork or not?

So is it good even wide-open?

Please could you send some shoot (especially wide-open)?

Here are a few from the desk top. Auto Chinon 135mm f/2.8

All samples shot at 2.8

This lens gets progressively sharper as you stop down. I think this lens performs well above average.

Which camera and Iso do you use for the example?
Is the 135mm f/2.8 or the f/3.5?

Very interesting the shoot on the Mandarin Duck because is against the sun but i don't see CA where is present only a little on the head of the gull.

Perhaps have you use a Pentax k20d? But which iso?
Some outdoor shoot in critical light with detailed subject?

How many blades are the 2.8 and the 3.5?

Also, in generale, why is so difficult found information about chinon lens?

[alelinuxbsd]

themoleman342 has had problem with the aperture on their older single coated lens now is the situation better?

Eventually could you send some shoot (2.8 or maximum 3.5) for test specifically regarding the flare?

[ManualFocus-G]

Part of the fun of older lenses is that they are really cheap to buy, and if you're not happy with them you can sell them on for usually the same amount or even more. Maybe you should try a few

[spiralcity]

[alelinuxbsd]

Nice.

I'm your opposite when i go to an event in general is an indoor event or night event so the wide open is a necessity.

Unfortunately often the strobes are positioned very bad so the presence of an eventual len hood don't help much.

What price is good for buy a Chinon?

[ManualFocus-G]

Mate

Seriously they are like £10-£15, really cheap. Just go and try one

[spiralcity]

[alelinuxbsd]

I bought the Auto Chinon Multi-coated 135mm F2.8 PK.
When it arrive I will do some shoot (don't test shoot but real shoot).

Note:
This is my first full-manual lens but probably don't the last ...
Yes before I bought even a 50 mm but was an A series so it is partially
automatic.

[ManualFocus-G]

[alelinuxbsd]

Sure.

Note:
Obviously the 50 mm that i referred was a Pentax series A
to avoid misunderstandings.
