I have the DA*200mm f2.8 and a KP but want more reach. What is the advantage to getting a 1.4x teleconverter? Can I reproduce the same or better IQ by cropping in post?
Also can I crop again effectively after using a teleconverter on a crop sensor? Thanks.

Moved to the correct forum. Product suggestions and feedback is about what you'd like to see Ricoh create. It's not the place for your questions.

Sorry. Lessons learned for me. Thanks.

TC pairings and resulting IQ are very specific to each piece of gear involved. In my experience, I have a rig where using a 1.4x or a 2.0x TC is ALWAYS better than cropping at a given focal length. I also have tested several combinations whereby it is better to crop. Maybe someone in here will have specific experience with the DA*200

[jddwoods]

The 1.4 TC works best with faster lenses of f4.0 or faster. That said it is a good match with your DA* 200. it will make it an 280 mm f4.0 lens. I have both and they work well together.

Assuming you use a good quality teleconverter, you are changing the focal length of the glass in front of your camera's sensor from 200mm to 280mm. This gives you greater magnification although the downside is you will lose some light.

By cropping a non-TC image (200mm) to the same image size as a TC image (280mm) you will be losing resolution. Will that be noticeable ? Depends on the quality of the TC (a poor quality one would even give you a worse image). A good quality TC should give you a better image quality, but the KP has a good sensor to start with and without knowing what you want to do with your images (view online or print) I would suggest it may be marginal.

Of course you can crop again, and this is where the TC may be advantageous. If you find you crop a lot you should always get a better result from cropping less with the TC (a good quality one) than cropping more without it.

Thanks for your response. With the APS-C crop that would be around a 420mm focal length right? How does that combo hold up to additional cropping in post? Thanks again.

The focal length would be 280mm (doesn't change due to sensor size), but if you got the DA teleconverter then the resulting image quality would be quite good. Another great pairing would be the 300mm F4.

The ISO you choose will affect resoultion in crop, lower ISO will allow for more croppng with less pixellation . What are you shooting pictures of?

[normhead]

Using the HD DA 1.4 you may as well be using a 300 ƒ4, it is a real lightweight telephoto solution. I also stack the 1.4 with the F 1.7x AF adapter to I've me 476mm ƒ6.3.

Birds primarily.

[Adam]

Hard to theorize about these things as it really depends on your expectations and exact shooting conditions. But I'd say for birds, the longer the focal length the better.

Current prices at B&H: HD 1.4x TC = $600, DA* 300/4 = $900.

DA* 200 plus HD DA 1.4 TC

DA*200 plus 1.4 slideshow

DA*200 plus F 1.7x AF Adapter Slideshow

DA* 2002.8 and stacked TCs slideshow.

If you have a DA*200 ƒ2.8, adding the TC and AF Adapter is just a no brainer for birds. The lightest most portable way to get to 500mm and by itself the 200 is the longest current 2.8 lens. That can be as important for birding as the longer FL.

As long as you have good light and a lower ISO, 400 and lower you can crop images with the 1.4TC with DA* 200 or DA*300 and still get a good sharpness. I use it on both lenses for shooting birds and am pleased with the results. You lose a bit of sharpness with the TC but it is more than offset by the gain in focal length, especially the DA*300 which becomes a 420mm f5.6 lens combined with the TC.
