Originally posted by subidoc Here is a question: I have a 40mm Ultron - the only VL I have. I also have an A28/2.8 and M100/2.8. As you can see, there is a gap between the 40 and 100mm ranges. I would like to fill that gap with something. Other than the 70 or 77 from Pentax, could anyone comment on the rendering on the Nokton 58mm? Would it be different enough to NOT be considered too close to the 40 mm Ultron? Should I instead sell the 40, and get the 58, or get both?
If my instinct is correct, then the resolution of the 58 would allow me to crop what I shoot, and "virtually zoom" to what I need. I really like to 40mm Ultron, both as a focal length and as a high quality lens. It has made me partial to VL....
Thanks in advance... because I don't know what to do.
I have both lenses, and they offer very different perspectives. Right now I am still drooling over my new VL75, but once that wears off I suspect I will return to my opinion that the VL58 may be the best lens ever made for Pentax. I know many believe the VL125 is better, but then unlike me, a lot of people really love macro ability and the kind of super sharpness a macro lens gives. Plus unavailable lenses can be more desirable than one you can still buy new, whether or not they are actually a better lens.
I've used the VL40 for landscape, where the scene is wide enough, because it offers a way to clearly see and control limited features of a big scene. The VL40 also is relatively fast, and indoors it is good for tight spaces. A fantastic lens.
But the VL58 is even faster and, IMO, yields better IQ. True, at F1.4 the picture is very dreamy, but that's been turned into an artistic asset by many photographers. At F2 the lens is sharper, and by F2.8 starts to yield serious resolution through F11. I use it for smaller nature scenes and flower "portraits" (and if I shot people it might be my first choice for a portrait lens), and I use it like I do the VL40 to isolate landscape scenes out of a wider landscape (links to examples below). Mega-resolution, mega-bokeh, vivid color rendering, and excellent speed all in one lens is a good thing.
Also, keep in mind that as you move toward wider lenses, fewer mm make more difference to the field of view. The difference between, say, 15mm and 20mm is far more noticeable than the difference between 85mm and 90mm. That's why you might see more lenses at the bottom of a kit than the top.
In terms of building a kit, I know some people love to collect lenses and have great variety, but others of us prefer (and/or can only afford) one set of lenses to cover the main focal lengths we will use. For example, after deciding to use only primes, I chose 9 FL "spots" I wanted filled with a high quality lens: 20mm, 28mm, 40mm, 55mm, 75mm, 90mm, 135mm, 180mm, and 300mm.
The FL was approximate, i.e., the 20mm spot could be a 21mm, or the 28mm a 31mm, etc. My 55mm spot is filled with the VL58, the lens I use more than any other (but that's my style, not necessarily yours). I still need to fill the 135mm (I'm looking at the Zeiss Jena, which can be had mint for under $200), and the 300mm, which Pentax A seems a good choice. I just acquired a Contax-Zeiss 28mm (I put on a Zeitax adapter), and I am really blown away by its quality (review is in the works). If I had to live with fewer lenses, I could be very happy with the 28mm, 40mm, 58mm, 90/100mm, and 300mm focal lengths.
So to (finally) get to an answer for your question, I think the VL58 would be the perfect lens to serve between your VL40 and 100mm lenses. Now that I have the VL75, I see I could have easily lived with just the VL58 and VL90 (another amazing lens), though the VL75 has a unique IQ I am thrilled to have. Still, it isn't so much of a
necessary FL on APS-C (I suspect the 135mm slot won't be all that important either, but I still want it
).
Bottom line, buy that VL58mm before it goes extinct and prices soar through the roof as everyone realizes just how fantastic the lens is!
