I think I only used one 'filler' from a different day this month too. Normally I haven't done this but here is my real assessment of the Pentax A 35 - 105 mm f3.5 aka, Bag-O-Primes.
The lens itself on a performance standpoint gave me some exquisite results in terms of focus, color rendering, and to some degree versatility. Whether or not my presentations could be considered exquisite is matter for another discussion. There are few quirks with this lens however that, I really didn't notice until I started doing focus stacking later in the month.
First, Anyone who knows this lens knows that in Normal mode, one can focus at 105mm and zoom back to 35mm and the photo will still be in focus (macro setting aside). The information has always been right in front of me, On the lens so I guess I should have known this but, the reason for staying in focus is that Pentax made the Minimum focus distance of this lens about 4.5 feet or 1.5 meters. That's all well and good except for when you Want to get Close but not use the 'macro' setting (in which the lens behaves as a normal zoom with close focus). That is, one of the advantages of a wide angle such as 35mm, is that you can get to within a foot many times. Not so with this lens. In Normal mode, the lens has the minimum focus distance of the 105mm end. As I said, this is all laid out, on the distance scales engraved On the lens. Since I had never used it however, I never paid much attention to it.
What does that mean.. Well, in the case of focus stacking model trains as I've been doing for the past couple weeks, Camera placement is Absolutely Critical. The idea behind focus stacking is to be in focus from Front to Back. Well, in the confined spaces of a model train layout (and I suspect elsewhere as well), that can be quite tricky to get the Front in focus. The middle and rear parts for the photo are not a problem of course. One can cheat a little and slip into the macro mode to get the front but it seems to change the perspective a little bit and plays havoc on the stack. On the flip side, with the macro mode, you can easily get the front, but moving further back (on anything more than a foot or so long) becomes the challenge. This could be applied of course to many things, not just model trains but that was the most cooperative subject I had this month.
I have to say that the point of this game being to 'curb LBA' it is also to get to know the equipment. How to use it, where it works best, and for what type of photos. This is the month I would say I've learned the most in that respect. Everything from the camera and lens itself to processing for the final image. I REALLY appreciate all of your comments and support, probably more than you'll even know. I've fallen short on returning comments but know that I've looked at all of your photos (if you linked in the group threads) and overall, they are just stunning. That's what keeps me going with this even if I complain about the grind. Thank you all very much. The Hound sends his regards as well.
On to August with the FA31, a gripless camera so I can carry a smaller package for once, use auto focus again, for hopefully, some fun shooting.
