I bought two lenses.

1- konica 35/2,8 AR.

2- SMC PENTAX K 28/3,5

They will came the next week, I guess.

The konica is a good lena.

About the smc pentax k 3,5/28 any reference. I found nice images in the net. Your experience? Pros and cons?

I think it is similar to the SMC 28/3.5 M42 mount. A very good lens which works well on my Sony A7.
You will find much feedback on Pentax forum.

Oupps! I check it out. The K mount has 8 elements and the older M42 7 elements.
my opinion is based on the M42. Sorry.

SMC PENTAX K 28/3,5 is one of the best 28mm lenses around. It's rather big and heavy for a slow moderate wide angle. Pentax built it as an ultimate landscape lens rather than a cheap alternative to faster glass (as was the case with SMC Pentax-M 28/2.8 and 28/3.5 variants). If this is the "K" version, you can't go wrong with it.

Note: it's a different (better) lens compared to SMC Takumar 28/3.5. It's also better than the later versions (SMC Pentax-M 28/2.8, 28/3.5, and SMC Pentax-A 28/2.8, although the "A" version comes close in terms of performance).

I have this lens too (SMC Pentax 3.5/2Cool , it`s just WOW, alot of contrast & resolution!
Much better than the SMC Takumar 3.5/28 or the Pentax-M 2.8/28.

There are a couple of reviews here http://erphotoreview.com/wordpress/?p=3039

In my opinion the lens is not bad. But the M 28 2.8 II and A 28 2.8 are sharper at wider apertures. The 3.5 models (K and M) are good at F11 with almost no CA and good contrast and colors. I shot one film with this lens once - awsomness! Great colors and contrast. On digital it is good too but many zoom lenses from nowadays are sharper.

it seems that the Alpa Merfcure 28, identical to one of the Asahi Takumar 28s was accepted as having a fairly flat field and reasonable resolution since it was used in the Alpa repro device.

SMC PENTAX K 28/3,5 ? Best 28mm lens I have ever owned, a true classic. NO corners cut in manufacture. Do not sell unless really desperate.

Pentax F 28mm f2.8 razor sharp wide open and up, beautiful lens but expensive $300 plus.

What is Pentax F ? I cannot find it on Pentax forum. Is it a FF or APS-C lens?

Pentax F are the first line of AF Pentax lenses, they are FF. Pentax lenses made for APS-C are called 'DA'
The F lenses are featured at Pentaxforum: http://www.pentaxforums.com/lensreviews/SMC-Pentax-F-Lenses-c29.html

I took the little Pentax on my morning walk.
The weather was cloudy and dull but the lighting was gentle.
Here are some pics.

Very nice, I picked one up recently and haven't really tried it out properly. I shall certainly do that now. Like 1 small

Thank you David.
This might be only Pentax's second best 28mm lens after the "Hollywood", but I find it to be awesome.
Here is another picture from this morning.

The new Pentax line of FF lenses are marked D-FA here's a link to the lenses. https://www.pentaxforums.com/lenssearch/?format=ff&series%5B%5D=D+FA


The F lenses SMC Pentax-F

First generation autofocus lenses
Sub-categhory: F* (professional)
Image format covered: 24 x 36 mm
Suitable for APS-C digital sensor format and 24 x 36 mm "full frame" format
Autofocus with screw drive system
Aperture ring
Automatic aperture setting is available*
In production: No

Lenses in this series work just like FA lenses.

The F series consisted of 20 lenses is now fully discontinued.

The F series also includes 3 "star" lenses that employ the finest of Pentax optical and mechanical engineering.

*Exceptions: The smc PENTAX-F Soft 85mm F2.8 and smc PENTAX-F Soft 28mm F2.8 lenses have no "A" setting on the aperture ring. Hence they work like smc PENTAX-M lenses with respect to exposure; they are still autofocus. The "A" setting has been removed because the degree of image softness is controlled by the aperture ring and it would be meaningless to let the camera decide the setting.

A, F, FA and D FA lenses work on all Pentax bayonet cameras ever produced. Exceptions: 1) A lenses do not work on the MZ-60/ZX-60, 2) the D FA 100mm F2.8 WR and newer D FA lenses have no aperture ring which restricts their use on some film cameras.

FA J, DA and DA L lenses only work on cameras which can control the aperture (since these lenses have no aperture ring). DA lenses should only be used on cameras with an APS-C sized sensor (16 x 24 mm) with the exception of the DA*200mm F2.8, DA*300mm F4, and DA 560mm F5.6, which can also be used on 24 x 36mm full-frame cameras.

DA lenses having the KAF4 mount only works on cameras which can control the aperture electronically (K-50, K-S1, K-3 and newer).

M and K lenses work on all cameras except the MZ/ZX-30, MZ/ZX-50 and MZ/ZX-6. They work with limitations on the *ist film camera. They work with stop-down metering on the *ist D series and K series digital SLRs provided that a custom function is set appropriately.

This old F lens will work perfect with your APS-C format.

That is a Takumar-f Cheaper version of the F line without SMC coating or the Pentax brand name. To call these lenses takumar causes confusion to this day especially with People looking for a 135mm F2.5 Takumar :p.

I have Both the S-M-C Takumar 28mm F3.5 Pentax-m 28mm F3.5 and the Pentax-a 28mm F2.8. I like the Pentax-m best of those three.

Yes, Pentax can be a bit of a terminology maze sometimes.
And just to be clear - none of your lenses nor the one above are the SMC Pentax (K) 28mm f3.5
Good old Pentax - making things difficult Smile

It's just an example, but in any case that lens works fine for a cheap find. They can be had for 20.00 on eBay, plenty of samples out there from this lens and at 20.00 dollars it's a keeper.
