New lens time
I have it in Canon mount but I only use EOS film cameras as they don't suffer from poor dynamic range like their digital Canon cousins :) It's certainly enjoyable to use and feel good in the hand. I haven't seen any scans back from it yet anyway as I got it quite recently, though I did have a br...

Is this the reason why SDM lenses need to be used often and are prone to fail?
I was reading a forum post the other day about the unreliability of he SDM lenses, e.g. DA*50-135 and DA*16-50. One of the things most often said about these lenses is that they 'need to be used often' and if they haven't been used for a long period of time they won't 'wake up'. Now, I used to t...

Is this the reason why SDM lenses need to be used often and are prone to fail?
Very interesting post David and I just sold a very tempramental DA* 50-135, (2nd one I gave up on) and had 4 other SDM's changed by ASAHI Optic (On 4 other DA* lenses). Two of them never ever failed or played up, one of which was the DA* 16-50, reputed to be the most unreliable, the other was 20...

My DA*16-50 caused me a bit of embarrassment recently as I sent it to SRS as part of a trade in only for it not to work when it got to Watford :oops: It's had a replacement SDM and circuit board at JPS, I never had any problems with it and it did (still does) work on return from SRS:!: It's be...

Which legacy lenses for K1?
There's probably still limited knowledge on this one, but I've been looking for a 20-35mm f/4 FA lens and perhaps the 20mm f/2.8 as starting points. There's also the MF Samyang 14mm f/2.8 that is fairly inexpensive and just might be worth having a go with. Not legacy lenses but Laowa have a FF 15mm ...

Which legacy lenses for K1?
Though not 'legacy' in the real sense, the Samyang manual focus options are a compelling choice for K1 users ..... perhaps not so much the longer ones (eg 85 / 135mm), but certainly the wider ones. I don't think manual focus is such a concern with wide angles, and the sort of landscape and architec...

Which legacy lenses for K1?
Well I'm sure my approval for the Samyang 14mm is well known around here, as are many images I've shown taken with it, so no need to rave on any more. I include the Samyangs here in this 'legacy' discussion, not because of the optics, which are modern high quality designs and benefit from modern coa...

Which legacy lenses for K1?
For me, I'm thinking now that I have a D FA 28-105 ............ If you are anything like me it would have occured to you, only seconds after the box arrived, to check out your new toy against the F 35-70mm which we both have. Did you do that? Did you form any conclusions about how they compare ov...

Which legacy lenses for K1?
Well, when I was buying it I saw reports from Chart tests that placed the optical performance above the Nikon Full Frame equivalent lens (albeit an AF lens), and that is nearly 4 times the price of the Samyang !! The glaringly obvious comparison of course is the Manual focus vs Autofocus aspect ...

Which legacy lenses for K1?
None of those, sorry! Most, or should that be all, of the old legacy film lenses will work with the K-1. Obviously results will vary so you need to define 'best'. One lens may produce an effect the photographer likes whereas someone else thinks otherwise. An APS-C example of this is the Sigma 10...

Which legacy lenses for K1?
Thank you for your suggestions! However I was looking for something more practical, with real tests made on the k1. I am not sure what I'll buy yet, but I have already got the 50 fa 1.4 the vivitar 1 105mm macro (a blade) the fa 80-320 and a 28mm pentax A. I'll very likely buy the 28-105 as all aro...

Which legacy lenses for K1?
Why is the Pentax 15mm superior in every way for daytime shooting? I think that would be very difficult to argue, even on a theoretical level. Of course you may have practical experience to explain it more .... ? I would have thought that a more realistic view would suggest there are a range of pros...
