Hey, all --
Yes, I know how to use the search feature. Yes, I have used the Google machine. No, I am not lazy. No, I am not trying to ask a redundant question.
I'm also aware that the Pentax 77 has achieved mythological status and, thus, asking for a comparison to a third-party manufacturer will be tantamount to blasphemy in some eyes.
I realize that this question has been asked before but the discussions are old(er) and I'm wondering if there's any new, relevant information.
Basically, I recently purchased some new gear that included a Tamron 70-200 2.8 -- was planning on mainly using this for portraits, mounted on a K-3 body. The lens itself is stellar, and the image quality is great, but only when I am able to nail focus. Between the weight and dimensions of the lens and the slight variability in autofocus accuracy, I'm finding that I don't have as many keepers as I would like. The photos that are good are really good, but don't necessarily have a ton of character. The dimensions are also intimidating for all but professional models.
I am capable, if not a solid photographer. I want a piece of glass that I can rely on to be consistent in the quality and caliber of imagery it produces. I am by no means flush with cash so I am somewhat nervous about such a large investment -- especially after my experience with the Tamron.
So, my plan is to return the Tamron and purchase either the Pentax 77 or Sigma 85. The main uses will be for portraits, lifestyle, and candid street photography. I'm starting to earn a living from portrait, family, and lifestyle work so I need a workhorse lens to support my growth as an artist and professional.
I know that the Sigma focuses faster, is sharper, and is better in low light. I also know that the Pentax tends toward creamier bokeh, has pixie dust potential, and has more character.
I guess I am looking for opinions from experienced photographers who have spent time with both lenses. The photo examples really don't say much as the images tend to be taken with different bodies, in different locations, with an array of lighting, in the hands of photographers ranging from amateur to pro. In other words, I can't discern a whole lot from looking at the photos other than the fact that these are both stellar pieces of glass. I will say, at least on the Flickr group, the 77 images tend to be more heavily processed which makes it harder to evaluate
I am open to any insight, suggestions, thoughts, ridicule, etc.
A friend of mine recently suggested I wait on the Sigma because it was recently announced that the current 85 1.4 is discontinued and will be replaced by an Art version at some point in the [potentially] near future. Given this, I considered going for the Pentax 77. If I am not impressed, the resale value is currently rock-solid -- I could always sell and fund the 85. Food for thought.
Anway. Sorry for the long-winded question. I suppose it's part question and part thinking out loud. Feel free to berate me if this post is in bad taste!
Thanks all!
Cheers,
