I stumbled across it while looking something up in Google and immediately went to B&H to check it out and there it was for about $96. So I ordered one. Its free shipping eligible there although ...

First there is the Sigma 100-300/4. If you can't afford it or the weight is an issue anything else will have to do. Maybe a 70-200/2.8 but just as heavy and not as much reach without using a TC ...

Could not pass up the deal on the 35/2.4 today for less than $100. Need some kind of standard lens for my 2 K-5II/IIs cameras since I have a 50/2.8 Macro for the K-1. Kent Gittings

Tamron has not made a 300/4 ever I think. Did make a good 300/2.8. As for Sigma the closest one is the Sigma 300/4 Tele-Macro and its pretty good. Or the Sigma 100-300/4 EX DG IF which is very ...

I mean its possible to like the effects but most of these images would be called bad bokeh by the original definition of the term. Good bokeh is a smooth OOF background with no highlights to ...

Just remember not to use any Ricoh K-mount lenses on your Pentax cameras or you won't be able to get them off with taking things apart. Kent Gittings

Although it looks softer in the snow patterns where its losing detail. Kent Gittings

Its funny. In the film days we tended to downgrade the 80-320 because it had a lot of things we did not like. I suppose it may have some new life under the digital sensor. I have noticed over the ...

Most of the time you are panning you have a shutter-speed you want to use based on what the subject is doing, whether its a runner, a racecar. or an airplane. So using shutter priority to keep ...

Just like everything else its the law of supply and demand. They have little intrinsic value except to those who need them. I bought mine around the early 90's I think from a camera store in PA. ...

Actually the SMC coatings do nothing in the way of anti-reflection off a digital sensor only the newer HD coatings do that. They may be an improvement over the even older Super Takumar or Takumar ...

I was wondering about that. I use a ring light when I can on my Vivitar Series 1 105/2.5 Macro (Lester Dine lens) before I will use my modern AF Macro lens (also my D-FA 50/2.8 Macro, while ...

Ditto on the 150-450 whether its on my K-5IIs or my K-1. I also have Canon, mainly because it was the only model of the Sigma 100-300/4 I could find. Recently got a Canon EF 1.4x II, which is ...

The Sigma 50-150/2.8 is also good (APS-C equivalent to the FF 70-200/2.8 basically). To be honest, in APS-C to be equal to the true 85mm portrait lenses perspective wise you need something around ...

You are really lucky to find one of those in PK/A and be a possible NOS (New Old Stock) one. I have a rare Vivitar Series 1 105/2.5 Macro in PK/A (the famous Lester Dine lens). I still prefer it ...

I was on an expedition in Central America many years ago. We didn't visit the rain forest we lived in it. Guys with not so weather-sealed cameras ( as in the Canon EOS-3) had a lot of failures. ...

In the Pentax world of the past and present, generally silver is pro and black is consumer. Kent Gittings

They don't use ED coatings they used doped glass to make ED lenses. That is where glass types like Ohara FPL-53 and Hoya FCD100 come from. In fact Canon has replaced CaF2 with FPL-53 in many of the...

When I got my K-1 I never sold off my K-5II or my K-5IIs. I considered selling them if I got a K-3II but have never done that yet. When I need more reach on the Pentax 150-450 I grab the K-5IIs. Ke ...

The X-700 will work with that lens. Just remember that without the battery an X-700 does not work at all. No mechanical shutter at all even in bulb mode. MD lenses are from the pre-AF days. Kent ...
