Thales, apparently you're overseas (at least from a US perspective) but where do you plan on getting the Sigma 100-300? I'm looking for a copy of this lens.

So Sigma HSM lens will work with their TCs on Nikon mounts?!?

Interesting, that is definitely something to consider.

Ok, so I'm a little confused. Does the Sigma HSM lens work with the TC or not?

I looked at the webpage and it seems to show them working for some but not all?

Thanks.

alexeyga -- I've been looking and haven't found any or just a little too late. If you know where I can find one please let me know.

I've pretty much made up my mind that I'll stay with the K5 (after I switched about 3 times today). I'll do some research on the 70-200 Sigma (non-OS) and how to performs with the 2 tcs so that way I have a lens for basketball as well.

The 55-300 would be nice to experiment, I'll keep that as an option.

Unfortunately, the Sigma 120-300 is not an option right now, but the other thing that is frustrating is that the tcs don't work with it and I thought I seen someone post that Sigma has no plans to produce one (although that could change).


Edit: As I re-think this, that means I couldn't use the 70-200 either unless I find an older copy. smh

Thanks all for the discussion/tips/comments.

Last question, I think, if I get the K5 what lens would you suggest. I agree the 250 is probably too short but:
1. Would really like the flexibility of a zoom
2. Sigma 100-300 is discontinued
3. 60-250 too short
4. DA* 300 too restrictive (and hit or miss on tc)

So?
1. Sigma 70-200? may work with tc (1.4 or 2) but would like to find non-OS version
2. Pentax DA 55-300, not sure if this fast/sharp enough

Shooting conditions:
Let's assume bright sunny day looking to shoot motorcycles road racing without track access, so constantly at the long end (obviously this would very).

The small primes is something I'm definitely interested in as I already have the DA 21.

Eruditass, thanks for the post. Obviously speed of lens has something to with overall AF ability/speed.

What do you think of the K5 + DA* 60-250 in terms of AF speed? Also, the sigma 150-500 has more reach and HSM.

So I thought I found a place that had a leftover Sigma 100-300 but they are out. Which makes this decision even harder.

Apisto, do you think the K5 is capable of tracking motorcycles? I know initially my skill will be the limiting factor but want something I can grow into.

All, thanks for the input.

So I guess the question is really:
1. How much will AF speed matter in shooting motorcycle racing?
2. If I went Nikon, which lens would you recommend for this type of shooting?
-- I didn't necessarily think it was a fair comparison (siggy vs. nikon) but I'm not to familiar with Nikon and after doing some limited research I kept reading that the 70-300 AF speed was superb; but price wise they seem to be in two different categories.

For those of you that have handled both, how much bigger is the D7000 than the K5?

All,
I'm loooing for some thoughts on the combos listed above based on AF speed and image quality. Not trying to start a brand war, just good opinions.

I think the image quality is a wash wrt just the cameras but obviously once you stick another lens on there then there is another factor added to the equation.

I really want to get deeper into motorcycle roadracing photography this summer. I'd also like to stay w/ Pentax K5 as I like the small size, ergos, and most of what they offered lens wise would meet my novice needs.

My major concern is AF! Is there much difference between the these combos (if I can find a 100-300 f4, if not I will probably go 150-500 if I stay pentax) and how much do you think AF will matter? AF shouldn't matter much in panning, right? Entering in/out of corners depending on where I'm located could have the bike coming at/away from me.

I have a K10D and have some ok shots but think AF has held me back and I also would like a further reaching lens. So the plan is to upgrade in the next month and hit the track.

As far as switching systems, I only have the the two kit lens, FA 50 F1.4, DA 21 and 360 flash. My other interests is getting into strobist, basketball (probably strobed) and just general shooting on vacation.

Thanks for your thoughts/opinions.

So what is the verdict on the AF speed of the lens? Looking to use it for motorcyle road racing? Do you think a sigma 100-300 f4 w/ tc would yield better results?

Definitely looking for your thoughts on IQ and AF. I am looking for a roadracing lens for this year. Now the Sigma 100-300 is discontinued I'm not sure what to go after?

The K100D and K10D came out at the same time. I remember b/c I orginally purchased the K100D b/c the K10D was on backorder. I would eventually uprgade to the K10D. I'm pretty sure that the K100D super came out afterwards allowing the SDM.

So if we're talking about production dates (or offering to public) I think he is correct. Right?

jsherman999 - I've been around for a few years noew just normally read and hardly ever post. I must missed that part in the agreement when I registered!!:lol: Nice pics by the way!!


Hawaiianonline - looks like that will be awesome but way out of the range I'm willing to pay for a lens; unless that was an offer to help pay :D

Pentaxor - I've debated this since I don't have much invested in Pentax but I like Pentax cameras for a variety of reasons. One of them (I must admit) is being the underdog. Although my reason for wanting the lens is primarily for motorcycle racing so it may be better to with a different mount. :hmm:

Odd, I just searched yesterday. Well thanks...I'll go check it out.


Edit: I see why now as it was only posted today but thanks for the heads up. In the meantime, I'd still like to know if this can be purchased anywhere since it seems that two others already have dibs on the one in the marketplace.
