Tamron 70-200 f2.8 need lighter weight

**csa** · 03-14-2022, 06:30 PM

This lens is very heavy for me, and used very little since I have the Pentax-DA* 300mm F4 ED [IF] SDM. It is also hefty for me, but for now will keep it. Question is, what would be a good lens to replace the Tamron that would be a good fit with the 300? I do mostly wildlife, birds, etc.

My goal would be to replace both lenses, with a great, lightweight telephoto, at least 400mm. Probably a dream, but open to suggestions.

Thanks

Hey Carol.

Not sure if there is going to be a viable option for a 400mm, if the *300/f4 is starting to get too much, But, I think, the 50-300PLM may be the lens for you, fast AF, folks say they are having great results for it, covers your 70-200 range, goes up to 300mm, plus quite a few folks are again having great results when paired withe the DA1.4x tc. makes 420mm at the long end, that would give you the reach you want, but keep the weight down.

There is no better lens the the DA*300.

The 70-210 f4 is a little lighter.

The 55-300 PLM is definitely a lot lighter and more compact, but you're really giving up a lot of speed with that one. Still, it's known to be a great lens, and a lot of people post great wildlife shots with it. I think some people even use it with the 1.4x TC in good light with good results, and that combo might fit the bill to get you past 400 without being too heavy.

I would probably hang on to the 300 f4 for times of lower light or when you want more IQ, though. You could look for a copy of one of the F* or FA* 300mm lenses, which are basically the same lens as your DA*300 but a little smaller.

Have you considered using a monopod and 1axis head to help hold the weight up and steady? That might let you use larger lenses comfortably, and the 150-450 (or a bigma if you're not looking to spend that much) sounds like it would really be what you're looking for, if not for the weight.

Thanks for the suggestions. I have a monopod, tripods, etc., but just walking around outside to get some photos, just doesn't work for me.

I definitely don't want to drop below 300mm.

Both Tamron and Vivitar had 400mm, F5.6 manual tele's that could produce good results in reasonable light and played well with a 1.4x converter.

The newer SP 200-500 f5.6 (31A) is certainly usable. Images below are from the even earlier CZ 200-500 with a K200.

I've never felt hindered by manual focus extra-long tele's given consideration for lighting and support. Manual lenses of that type are typically 20 - 40% lighter than the AF variety and much less expensive and they have zero complaints about slow AF issues.

Not the same IQ class as a DA 300, but the K-3's hi-pixel sensor's ability to crop is a tele-plus too.

**othar** · 03-15-2022, 12:41 AM

I think your DA 300mm is as light as it gets.
I use a Tokina SD 400mm F5.6 for wildlife photography, it is marginally lighter (and longer) than your 300mm lens, but you loose AF (and tracking birds in flight needs some practice) and while it is a sharp lens it shows some color fringing and is best used around f8. As you already own the DA 300mm lens it is probably best to buy the DA 1.4 teleconverter to get more reach

My opinion, for what it's worth....

Keep your DA*300, and consider the HD DA 1.4x rear converter. It is the perfect compliment - like they were designed to work together

Your Tamron is probably the lightest f/2.8 full frame telezoom going around. If you are shooting crop I would consider the fantastic DA* 50-135/2.8 instead. It also works very well with the teleconverter. Or the DFA 70-210/4.0 if you want a smaller focal length gap to the 300.

On the other hand, if weight is absolutely crucial, and a slower aperture is not a deal-breaker, the HD DA 55-300 PLM might be your one stop shop.

**PJ1** · 03-15-2022, 04:22 AM

Sorry to hear weight is becoming a problem, Carol. I guess there is no magical solution to that because bigger sensors require bigger areas of glass. I love my Pentax gear - my K-3, K-01 and Qs - but working around the bush, while weight is not a problem for me (yet) coping with an array of expensive lenses under less than ideal conditions is something best avoided. For that reason my general walkabout camera has become a Panasonic Lumix FZ200 bridge camera with a Leica zoom lens that - on the 12MP 1/2.3"sensor - gives the equivalent of 24-600 mm at a constant f2.8 if you like. There are some downsides to it, but it gives me a lot of flexibility and I can still use the Pentax when photography is my main goal. (I got my Panasonic used (almost new) for $80 Australian, which was a bargain. It wasn't hot but I suspect it was a case of "hell hath no fury like a woman scorned". So we were both happy with the deal.) The later FZ300 is weather sealed but the most recent one is the FZ2500 has a 1" sensor and less zoom range (about 25-250 equivalent). Something to think about maybe. You have to enjoy your photography.

Crop or full frame?

If crop I’ll echo Sandy, The 50-135 is a great companion to the 300 particularly if you have the hd da 1.4x along with it. The 55-300 is another good option.

Cheaper and lighter still is the 50-200 but that lens isn’t the best - but stopped down it’s made good images for many people.

If full frame, The D FA 70-210/4 seems like a good fit. Various 70-200 or 70-300 variable aperture zooms might work. The FA 135/2.8 might fill the gap.

**cdd29** · 03-15-2022, 06:06 AM

what about the old trusty Sigma 400/5.6? Pretty light weight

**csa** · 03-15-2022, 07:30 AM

Thanks all, given me a lot to consider; and it seems that I'll just have to cope with the weight, especially with the 300. Also I do have the Tamron 1.4 TC that I use with both lenses. I really also don't mind manual focus lenses.

Since my illness, it has become difficult for me with the heavy lenses. I'd consider the 150-400; but it's heavier yet. I'm using the KP with these lenses. I also have a K3.

PJ1, thanks; but I want to stick with Pentax; I have too much money tied up in it, and really love Pentax!

If manual focus works look up the 75-150 zoom. Very good image quality and light. It plus the 300 might work. The D FA 28-105 is another idea - it leaves a gap but might work if you are willing to crop a bit. Or the 50-135 even if you are on a k-1 the crop 15mp images will be really nice.

I hear you. I stick with Pentax too when I am not just being "rough and ready".

normhead · 03-15-2022, 06:34 PM

I leave my DA*60-250, DA*200 2.8, and Tamron 300 2.8 home as often as I can. If the light is good to excellent I take the DA 55-300 PLM. IN poor light it may have issues, but if weight is the issue, having a 2.8 or even ƒ4 telephoto isn't the answer.
