Default New Lens for K7 - Guess What Lens

While the K7 was gone I acquired a 32GB SDHC Card and lens for my K7.

Here are some photos, Tell me what lens.

Photo #3 I have not seen before. Was growing on the ground and was jus over 1/2 Inch (15mm) in diameter.

From the bokeh I don't think it's the Tamron 90 or Sigma 105 so I'll guess that it IS a macro lense and say the Pentax 100 macro WR.

Hmmm... I'd say the 180mm!
Nice job, Ed!

Default Vivitar 90 180mm Flat Field Macro

It is actually an old lens. This Vivitar is totally manual, focus and aperture, and I am still learning with it. The phocus is no problem, I use manual with auto focus lenses for macro. I am finding that when using a flash the shutter speed needs to decrease as the object is further away. I have found changing the ISO is actually the fastest way to adjust, between 100 and 400 ISO. Any suggestions are welcome.

Hello snooked!

First off, let me start by saying I love your photos. They are sharp. Great colour. And using the flash helps to make you subject stand out by making the background a little darker! I love it.

As for having to adjust for distance by either changing your shutter speed or iso setting . . . is this because your lens must be set manually and the camera does not know what f-stop it is at.

If so, maybe using an external flash in "AUTO" mode (rather than P-TTL mode) might be a solution.

The external flash, with it's own built-in sensor, would be able to adjust how much light it sends out based on how much gets reflected back.

Take care, yours truly,
Glen

Don't think I've heard of that particular lens before, Ed.
You've done a great job with it so far. I'm one that uses manual mode on the majority of my Macro shots anyway so I cant see paying extra for something I don't use anyway. Looks like this lens is a keeper!
