Hi,

Any experiences...And sample pictures with Pentax DSLR ?

Worth of 200€ (used M42 version) ? (my another alternative is Sigma 10-20mm, but its price is 500€ here in Finland)
Thank you for help !

It will give you a small clip (black area) in each corner, plus a lot of distortion. I have not used the Peleng, but I suspect that you will get better image quality from the Zenitar 16 mm F2.8 fisheye. I believe it can be bought in the U.S. for about $150, and that will be in K-mount. You can probably order it from Russia in K-mount for even less. It has a little distortion, but less on APS-C than in 35 mm. The Zenitar is quite a sharp lens, and many people here like it.

Here are some comparison shots I made a couple of years ago of the Peleng 8mm and Zenitar 16mm fisheyes vs. the Pentax DA 12-24mm zoom and DA 14mm prime rectilinear lenses on my *ist-D:

As you can see, the Peleng shows significant falloff of IQ near the edges of the image circle and it's not the sharpest of these lenses. Performance wide open is somewhat poorer than at f5.6, which I used for these shots. However, it's still the widest solution for use on Pentax digital as far as I know.

What struck me from Jim Kings nice examples was how well the 16Z did alongside some pretty fine lenses. I love my Z, and think most that have them feel the same.

...now I have much better opinion what kind of images these lenses can produce, thank you a lot for help !

Hi,

When I looked your sample pictures, I noticed that Zenitar can produce almost as wide pictures than Pentax 12-24mm at 12mm - and when corrected with PTlens, then about as wide view than Pentax 14mm lens...Is that correct although Zenitar is "16mm" lens ?

Does zenitar 16mm for PK mount support pentax "A" mode ?

I'm afraid not.

Okey - BTW, what you think about M42 ver. of that lens ? There is one used Zenitar 16mm M42 ver. for 180€ in local camera shop. Is PK ver. much better choice for Pentax user ?

I bought the M42 version from choice long before I had a Pentax dSLR, I currently use it on both Pentax and Olympus cameras and before that on a Sigma :-)

One thing though, it has no A/M switch so you need to modify it slightly so that it stops down manually when you turn the aperture ring. This is a very common modification to allow use with adaptors on various cameras so it may have already been done.

I find it very convenient to use in Av mode, it works well.

Hi there!

I was using Peleng half a year ago with my *ist DS. Nice shuts! On the film camera you gets 100% fish eye. Because of the crop factor 1,5 you will not get the same results. For the same results you would need 5,3mm/3,5-16. According to the instructions of my friend who owns it the sharp pictures are got with very closed aperture. I have been using it by taking pictures of Cessnas and Partenavia interriers.

Best regards

Franci
 
I really don't think so - it depends on the crop you make on the Zenitar image, I think.

What you say about these two lenses if we talking about only 16mm wide angle performance ?

I just wondering is there any point to buy fully manual 16mm lens for 180€, if I can get used Pentax DA 16-45/4 lens for 250€....;-) I already have sigma 17-70, but sometimes I hope slightly wider angle.

Any thoughts ?

If I had the Sigma 17-70 and needed something wider I'd buy either the Pentax DA14/2.8 (despite the criticisms you may read, it is an excellent lens IMO) or the Pentax DA12-24/4. Getting the DA16-45 would not offer enough FOV increase to do you much good, and that lens just duplicates the range you already have with the Sigma. Get something that is significantly wider!

All this presumes that you don't want the Zenitar 16 FE. If you don't mind manual focusing and exposure, are willing to defish images in software, and don't want to spend a lot of money, it's a fun way to get into wide angle.

In case you haven't seen it, here is a very useful chart showing the FOV of various lenses on a Pentax DSLR, created by Richard Day a couple of years ago: http://forums.dpreview.com/forums/read.asp?forum=1036&message=16090350

I think this shows why going from a 17mm to a 16mm focal length doesn't gain you nearly as much as a DA14 or a DA12-24.

Yes...perhaps I need start to save money more...lol.

One alternative could be also Sigma 10-20mm.

Getting the DA16-45

manual focusing and exposure are OK, if FOV is something like with 14mm lens and IQ "good enough"...

are willing to defish images

But can I get any wider images with zenitar than with DA 16-45/4 lens ?
