Tamron-F 28mm F2.8

There are several versions of Tamrons' fixed mount 28mm's. In style and spec the more common ones (pic 1) bear comparison with the adaptall CW28.

M42 is most common, PK and other mounts of the era. Pre-PKA.

Lens Review Date: February 9, 2014 I can recommend this lens: Yes | Price: None indicated | Rating: 9 

Pros: Good Contrast and Pleasant Colors
Sharpness: 9    Aberrations: 8    Bokeh: 7    Handling: 9    Value: 10   

How many versions of the Tamron 28mm f2.8 were there? says 4, maybe 1 or 2 versions becoming the early adaptamatics and there were definitely different formulas and designs

I have the Tamron-F and I have seen the very identical lens without the "F" designation . There are 52mm variations, 58mm variations, and a 62mm version....that 62mm version escapes me

The 28mm f2.8 Tamron-F has a high gloss paint and comes with a square hood, it's really a very beautiful looking lens and it is very well constructed.
Looks precise and feels precise in hand. No doubt Tamron was going for that Leica look and why not? Imitation is the most sincere form of flattery.

The Tamron - F version; (non-adapatamatic, adaptall, and adaptall-2 versions)

It weighs 230 g (8 oz) has 7 elements in 7 groups and was marketed in the late 70's. It's about 2 inches in length and focuses to 10". These have the 52mm threads for filters, I do not recommend using them with a digital camera and have mixed results mostly affecting focus. If anything I relate these F system lenses as the early SP, Tamron made these with a very specific goal in mind and this illustrates it .....

Lens Review Date: September 18, 2012 I can recommend this lens: Yes | Price: $40.00 | Rating: 9 

Pros: Overall sharp, from center to edge, nice colors.
Cons: Manual...?
Sharpness: 9    Aberrations: 9    Bokeh: 8    Handling: 7    Value: 10   

This is a gem, use it on my Canon 5D mark II most of the time.

It's as good as my Canon 24-70 f2.8 L! But much smaller and less bulkier.. and definitely cheaper

Lens Review Date: April 4, 2008 I can recommend this lens: Yes | Price: $20.00 | Rating: 7 

Pros: Low cost Legacy Lens.
Cons: Fairly large. Manual mode.

It's a heavy lens, coming in around 300 grams. The DA 16-45 is 360 grams on my scale. My copy had a nice smooth focus and the click stops on the aperture ring were snappy.

I've only taken some casual shots with it and rate it good. I haven't seen any purple fringing with it, One of these days I will compare it against my DA 16-45 and DA18-55.

Why would I use this lens over the DA16-45? I guess I wouldn't unless I wanted something slightly faster for night photos.

But for the price I paid, $20 USD , it is an optical bargain. It's the Tamron F series, which I think came in different mounts for other cameras.

Edit: I have now compared this lens to my DA16-45 on my K100D and it's hard to get the same results. I believe some of that is focus. For flowers ar 12 inches, images look comparable. For a landscape, the better focus with the AF lens makes for a crisper image.
