Minolta was one of the early players in the SLR market with the introduction of their SR-mount in 1958, only a year behind Asahi Optical Company's Pentax (which used the existing Praktica M42 screwmount), and a year ahead of the Nikon F-mount. More commonly known as the MD mount (which is really the designation of the fourth-generation lenses) the SR was a very advanced bayonet design for 1958 that required no internal changes for its 40+ year lifespan and thus avoided the compatibility problems suffered by most other concurrent mounts as they had to modernize or adopt completely new designs to offer auto-exposure capability and other new features. In 1985, when Minolta introduced its new Alpha (A) mount which permitted auto focus, the SR-mount was not immediately discontinued, but it was the beginning of the end, and by the mid-2000s it was an orphan. Which means great things for the bargain hunter. Orphaned mounts are in lower demand, generally, and therefore, it is less expensive to obtain lenses and accessories for them. Minolta glass is of excellent optical and build quality and equally at home on classic film SLRs or adapted for modern mirrorless digital cameras. So let's take a look at some of the best bargains around in vintage Minolta lenses.
This is the first installment of our Best Bargain Lenses series in which we attempt to sift out the truly best-bangs-for-your-buck in the legacy lens world. We are starting with the Pentax K-mount (bayonet) because of increased interest in vintage Pentax glass since the release of the new K-1 full-frame (35mm format) DSLR. You will find that most bargains lie in the focal lengths between 28 to 200mm and at moderate apertures (e.g. f/3.5 or f/4 for wide angles and telephotos and f/1.7 to f/2 for normal lenses). The beauty of these unassuming optics goes beyond their low prices; because of their smaller maximum apertures they were able to use simpler (most of the time) optical constructions, which saved weight and bulk and yet gave excellent performance. So let's start the party with the original series of Pentax K-mount lenses: the SMC Pentax models which were manufactured from 1975 to 1977 (offering the best build quality before cost-cutting entered the picture with the M- & A-series). As we go through we will consider each lens in context with its predecessor in M42 screwmount and successor in SMC-M. Prices are current as of 2016 and are an average cost for lenses in very good to excellent condition.
Google the above question and be prepared for a merry-go-round of answers and opinions across forums and blogs. It is not the intent of this article to find fault with anyone or incite riots ;-). It is, hopefully, to provide some clarity, which is not so easy, seeing as Nikon itself changed its position from "NO, ABSOLUTELY NOT!!", and "DO IT AT YOUR OWN RISK. WE are NOT responsible for any damage that may occur"...to "alright, it's okay, if you must". Logically, this raises doubts and questions, questions that I wondered about when I purchased my own F4. Why did Nikon change its position? What, if any, risk would I be taking by using lithiums in mine? This article is the result of my investigation of this issue. The conclusion I came to may or may not sound reasonable to you. I hope it will be of some help to someone :-).

$250 - $350 USD. That's what it takes to have one of these beauties for your own nowadays (2020). For those of us who couldn't afford to own a pro-level camera back when the F3 & F4 were current, now is a golden opportunity to obtain a little slice of photographic history that is as usable as ever. If you have ever picked up one after holding a consumer-level body, there is simply no comparison (Yeah, they are that solid & heavy! Especially the F4! :-)). Even with F3 values rising again (and at a faster rate than the F4's), it still comes down to the attributes most important to you, the individual photographer, when making a choice between the two (if you can't have both, that is ;-)). It is the objective of this article to clearly delineate the differences between the F3 and F4 that could influence your decision-making process. So here we go...

In 1976, Nikon found itself at a crossroads with its F-series of professional bodies. The F2 was at the peak of its domination of the market, with 125,000 sold in that year, the greatest annual total achieved by a single F model ever. Compare that to 36,000 Canon F-1s and around 8,000 Minolta XK/-1/Ms and clearly Nikon was sitting pretty with the mighty, mechanical F2. The problem was in coming up with its successor, the F3.
The reason for this struggle was that Nikon had to try and balance its desire to make significant strides with the F3 and yet not alienate its customer base of professionals, a group not known for rapid acceptance of change ;-). Especially change involving more reliance upon electronics (where are you going to get batteries in the middle of a fire-fight in the jungle, or what happens if you miss a deadline because of a dead camera?). So here was the challenge: Maintain high reliability and quality while: 1) incorporating automatic operation, 2) making the camera easier and cheaper to build, and 3) convincing pros that it was worth upgrading to. Nothing to it, right? So how did Nikon do? And is the F3 for you?
Suffers from a two-decade and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots, and (gack!) '90s SLRs. He even mixes in some digital. Definitely a sick man.
