28mm Sigma Mini-Wide awesome legacy bargain - tests

Think I paid $25 for this one. Great typical quality Sigma build. Fairly close focus at about 0.22M, 0.7' . Macro is stated as 1:4.5. Performs great straight from f2.8 all the way through.

The last shot is the closest focus at 100% AND at f2.8! All shot at ISO 200 with a Canon FD sample with a Fotodiox adapter on my new lens testing bench now with Windex Electronics, not recommended for use on lenses - for that get WIndex Lens.

OK now I really must go clean those f$%^&* gutters!

Very nice, always good to see a bargain that can take good pictures. Though I wouldn't consider an aerosol can an "exciting" subject.....but nonetheless.

Here is the lens on the 5N. Handles nicely. Focus and aperture a little stiff.

Oooh I have something special for the next test - Oh yes, you will like this one. Maybe tomorrow. Do you like things that go bang?

Thanks, Les

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

I have the 24mm f/2.8 Super-Wide II. Closest focus distance is 0.18m and macro stated at 1:4.

Similar build and size to the Mini-Wide, Good handling and the performance should be similar too. I will try to provide a few pictures whenever I find time and light... if you are interested.

Only the price is unfortunately slightly higher., but I felt more comfortable with this focal length.

I'll be expecting tomorrow's bang !

I would like your lens too. As far as I am concerned wider is better...

Yes tomorrow will be exciting.

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

That lens looks very nice on the 5n, I might have to consider this, if only they made it in f/2 or lower...oh well.

And yes! Me likey boom boom.

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

As promised, and since I got good light, here are pictures of and from the Sigma Super-Wide II 24mm f/2.8 :

f/2.8 :

f/4 :

f/5.6 :

f/8 :

f/11:

f/16 :

f/22 :

picture taken at the minimum focus distance at f/2.8 (which is more 10-12 cm, rather than the previously announced 18 cm, as a matter of fact) :

and to finish, a low-light picture at f/2.8 :

As you can see, the lense is sharp even wide open, corners are sharp as well.

I got it for 60 € 3 months ago, although it is more expensive (150-200 €) on most regular sales sites.

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

Hey thanks for those shots, it's a shame that wide open the bokeh looks odd (I see a lot of obvious rings with bright dots in the middle with highlights). Stopped down to f/4 and beyond it look very nice. I may have to pick up this lens if I can find a deal...again though, shame its max aperture isn't f/2. I would have loved that.

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

I am afraid you will have a hard time finding a 24mm f/2, unless you are prepared to pay quite a high price... and I am not even sure those would be sharp wide open, so you most likely will loose the stop you had gained if not more.

With regards to the bokeh 'rings', I do not find that odd since it is in the middle of very dark areas with rather harsh light. Unless you pixel-peep, you would not even see the 'rings'.

Anyway, I sure have seen better bokeh, but mainly much worse, particularly for wide angle lenses.

Figures...oh well. I'm really interested in the Nikon 50mm f/1.2 AI-s. Being manual everything anyway, it'd be just like using it on a Nikon camera with my 7. Nice they still produce it new today. Sharpest Nikon lens at f/2, period.

Perhaps my views were a tad subjective.

You make a good point. I kinda forgot how wide it was.

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

I just realized the bokeh problem was an optical illusion. Upon viewing the f/2.8 at full-size, I now see they are very even circles, with minimal point light showing. Also, tack-sharp on that bird house. Great stuff!

Re: 28mm Sigma Mini-Wide awesome legacy bargain - tests

It is a nice little and easy-to-use lens. If you manage to get a good adapter or if you correct it properly to achieve infinity, it is a pleasure for street and landscape shooting.
