I have recently forced myself to decide few lenses to go. My 70mm and 40mm limited are the ones to go. I am contemplating on 21mm as I like it for street shooting and people shot but I am tempted to try the crazy thing in Tamron 10-24. I wish someone have tried it on Pentax and tell me all about it. I don't trust reviews on test chart and soft this and sharp that. I like user real photo experience. It is not urgent as I love to keep my 21 as long as I can afford it. Having both the 15 and 21 is a blast for wide angle needs. And I have the funkiest liking on 10-17. So my wide angle needs are as complete as I think it is with 15, 21 and 10-17 for the fun factor. But you all know me in wanting to try out the unthinkable in Sigma 10-20 or Tamron 10-24 and swap with the 21. I know I am going backward with Justin.
Now on the 70/77 story. The 77 is insane every time that I use it. I shoot some shots wide open in many instances, it is still a reasonable shot. Fringing seems like a character that happen more in 77mm than the 70mm. But 77 is keen o sharpness and surreal color that make a picture pop over the 70. Its speed in f/1.8 allow me to go insane in indoor shots.
Here are few shots on a Goose feather. After a big crop, I can see the detail and I think it is really sharp. I hate Photography as an exact science like RH measurbation on image quality.
All shots taken with Pentax K-x and Pentax FA 77mm f/1.8 while the wind is blowing quite heavily on a clothing hanging line. Shame on some of the shots that are over exposed
#1 The set up
with cloths drying line and wood clips
I shot up into sky and a crop.
And this cat shot that I have no time to frame the shot. As soon as I open the screen door, I get about two shots with one that look down at the cat and I kneel down next for the head shot and right after the shutter release, he turns and heads upstairs. It is a giant cat.Again, I love the depth and the soft and very smooth off focus rendering, it helps to isolate the subject of focus greatly though I rush into the shot without much thinking.
Impressions & Notes
- As I have noted before. Color and sharpness is outstanding in FA 77mm f/1.8 limited.
- The fast speed in f/1.8 makes the 77mm limited all more of a great value when it comes to indoor and low light type of shooting. The bokeh in wide open is awesome but I do notice light falling off in wide open aperture. Care has be taken in using wide open aperture wisely.
- The FA77 and DA 70 limited are not keen on close up. But the sharpness in both lens can help you as a macro lens in cropping huge. In the test shots with the white goose feather, I did a large crop close to 85% crop and it surely looks like a macro shot
- Cyan color fringing are noticed in high contrast areas. It is unfortunate and some Pentax folks in community prefer the DA 70 limited because of the frequent fringing. I treat the fringing as a character in the lens as the color from FA 77mm offers surreal quality not matched up by the 70 limited. If fringing is a concern, go with 70 limited which also excels in sharpness and color and it has the quick shift focus that is absent in FA limited lens series.
- I thought often about the field of view after crop factor that adds up to roughly 115mm. It is outstanding in half body portraits but one has to zoom with feed. In actual shooting with outdoor portraiture, I actually like my DA* 50-135mm f/2.8 due to the zoom flexibility. But in terms of prime quality, color and sharpness, and compactness, few can match up with the 77mm limited
- Among the FA and DA limited, my favorite is the FA 77mm limited for its surreal color, great sharpness, and awesome speed in f/1.8 when I need to push and balance with ISO and hand-holding shutter in demanding situation
