Hi,
today arrived an early christmas parcel containing a fully manual Vivitar 24mm f/2 lens and of course I had to take some test photos. I'll share these as this or a similar lens might be interesting for some of you, too ;)

The lens looks good with the slightest signs of normal usage, mounts and dismounts correctly to and from my DL2, serial number starts with 28 - so this is a Komine made lens afaik.

The photos were taken in RAW and converted with Raw Therapee, minimal luma noise reduction and a tad local contrast enhancement used - and of course some exposure compensation, but no other postprocessing to increase sharpness or detail. So these are almost 1:1 straight from the camera. I combined the downsized image and some 1:1 crops.

#1 - first ever shot with the lens, wide open

#2 - my cat (this was mainly a fun shot, but it shows a more "real life" situation) - again wide open.

#3 gingerbread castle with small figurines, upper left is wide open, upper right at f/2.8, the lower one at f/2.4 (the aperture has "half" settings, so I guess between f/2 and f/2.8 is f/2.4?)

Overall feeling so far:

- wide open shots are soft and miss some contrast, but there are already a lot of details available
- things start to get much better even when stopping down just to f/2.4, images are tack sharp and contrasty at f/2.8

One of the best things is, how I won this lens - it was VERY close to say the least, here is how the bidding went. And yes - 52.52 was my high bid :G:blah:!!

So far I am happy! :D

Regards,
Th.

P.S. I almost cleared my lens wishlist with this, I'll sort the tele end in the near future (selling some stuff and trying to get a decent/affordable 200mm and/or 300mm prime in 2009 or 2010) and if I stumble across a real wide fisheye lens I'd be tempted to try it. As most of my lenses are manual by that time I'll have to sort out the "fully automatic, family-ready, walkaround zoom" thingie and the flash problem and I am set. After that I can start to save for a better body ;) sounds good, doesn't it?

With some basic postprocessing the cat looks like this, which isn't bad at all for a f/2 wide open shot. I'll try to do some cat shots with f/2.8-f/4 to show the differences later.

The lens at 2.8 is very good - even 2.0 is useable in a pinch. You can deal with the lack of contrast through pp easily and the softness isn't as bad as some lenses I've seen. It looks like an excellent buy.

As a (Bargain)LBA I am SO jealous.

I am awaiting a Tamron 24mm/2.5 I paid more for! Ouch.

Yes, that's exactly what I thought when I saw the first results. As someone that doesn't use the in-camera flash very often, I like fast lenses. The shortest prime I've got so far was the Pentax-A 28/2.8, but I was looking for something wider. I am a bit concerned about these "halo"-like effects wide open, but I'll see where this really hurts and where not.

The f/2.8 performance is exactly what I was looking for - as a first guess I'll use the lens mostly in that range: f/2.8...f/4 and that means it is already stopped down twice as a minimum!

My only complaint: a 52mm filter thread... I mounted a spare UV-Filter already, but have no polarizer and I bet this lens could give me some nice architecture and landscape shots...

Well - I lost most of my bids in ebay in 2008, the only exception being a Viv 90mm f/2.8 1:1 macro lens and the above one. What bothered me most, is that I had to let go some Tamron Adaptall "A" adapters as the asked price or the bids were insane... but I've got time... no Tamron lens in my collection so far, I managed to bid "around" this ;)

As for the 24/2.5 Tamron - that one and one of the tele primes (200mm, 300mm) are what the adapter would have been for - so I think you'll get a fine lens! For me the f/2 adds just a special something to that lens as I seldom use flash and then every tiny bit makes a difference.

Best regards,
Th.
