9/17/2023 0 Comments Helios lens f2 mount![]() ![]() This is one of those items in which its performance is greater than the sum of its parts. Apart from value for money (10) I have rated this lens at an 8 or less in every characteristic but give it an overall rating of 9. That I think is one of its main strengths - it will give you something different and fun, without being cheesy like some special effect lenses.įor the money I can see no reason not to have one. I also think it will be good to find some colourful subjects and really crank up the saturation and contrast in camera for some funky effects. I do like the narrower FOV compared to a traditional 50mm especially where I live now, as it cuts out a lot of distracting fore ground clutter of my local canals' towpaths. Oh and it needs a hood to protect against flare.Īs I say, I have only really just started playing around with the lens, but hopefully with some decent lighting conditions I can give it a proper run. B&W images exhibit great contrast.īuild and handling are OK but not great for a lens of this age, but still it's pretty decent and comparable to some of the cheap Chinese MF glass you can get for mirrorless these days. F2 is a bit soft though but not horribly so, stop down to f2.8 and things are quite nice indeed. The depth of field at wider apertures is significantly less than one is used to for a "normal" lens so focusing needs to be spot on and even then lack of D of F will make images appear a tad soft outside of the narrow band of focus. The other reason is that it is a 58mm and not a 50mm. I consider this glow to be one of the reasons some have found the sharpness wanting. The colour cast tends towards the blue which is nothing like a typical Pentax lens, but again you either love it or hate it, or just embrace it if you want a different look to your images. Highlights do produce a bit of glow at the wider apertures, which you either love or hate. It appears quite a bit sharper than it does on my K3. Well, I am actually pleasantly surprised in terms of IQ. I purchased a K1 ii in October 2021 and since then, having discovered that some lenses perform differently on FF than they do on APSC (some better and some worse) I have been slowly revisiting my lens collection with the K1 ii. It has sat on a shelf since unitl I re-discovered it a week or two ago. A little behind my K 55mm f1.8 or one of my 50mm primes. I have not managed to find the time to use it on my KX! However I did try it out on my K3 and apart from not liking the field of view on APSC I thought it a decent if not great performer. I wanted a 58mm in K mount which would not break the bank for my film SLRs as I really like the FOV provided on 35mm. ![]() I originally got this for about £25 complete with a non-working Zenit Automat. This is only an initial review which I will update once further testing has gone on and is only based on initial impressions. Sharpness: 8 Aberrations: 8 Bokeh: 8 Handling: 7 Value: 10 Camera Used: Film SLR's, K1 ii, K3 Manual focus and manual only exposure on DSLRs. ![]()
