Nikon D7100

[John_M_King]

It's a while since I posted on here but I need a bit of advice. I was intending to buy a Nikon D7100 to replace my D90, but have had to put the brakes on and wait until I can find out what I have heard about this camera is true.

I have a Sigma 105EX Macro lens (current model) but I have read that this lens will not auto focus on the D7100 camera body. As expected Nikon won't comment on the use of third part lenses.

Any comment for or against please.

I don't own a D7100 but I researched the camera extensively for a relative and could find no vices to speak of. He has since bought it and is delighted. Third party lenses are always a bit of a gamble because the camera makers don't disclose technical details about their systems like autofocus and importantly modifications to them but I would be a bit surprised if a current Sigma lens did not autofocus on a current Nikon camera. For what it's worth, autofocus on any macro lens is a mixed blessing in macro mode due to long lens travel and therefore a tendency towards hunting. Perhaps some reviewer has mistaken this for faulty autofocus. Be assured, even Nikon macros suffer from the same problem at times. OzJohn

Thanks for that and will agree about the hunting before locking on to a subject but it does this with both my D90 and F6. So long as the focus point tis locked onto a position with a good surface it will always fucus spot on. However the later lens which mine is, does not extend as far as I thought it would.

The possible solution will be to take it into a dealers and ask if I can try the lens on a camera. They usually will.

That's what I would do. I'd also try to buy the camera from them too, since they are being helpful.

You could also contact Sigma. They may have an update for the lens if there are issues.

I'm sure Nikon won't comment but I bet Sigma will comment. I'm thinking if there IS a known issue, then Sigma should/must be working on a solution. D7100 is a popular camera. I also wonder if there was a batch that didn't work? You might want to inquire if there were a firmware change on the lens, and if so if it is up-datable either in field or at a service center.

I have a Sigma fisheye and it works perfectly with all of my Nikon digital bodies. So they are capable of producing lens that works. (obviously)

When it comes to putting 3rd-party glass on a Nikon DSLR, you "pays your money and you takes your chances".

The Tamron 150-600 is a noted AF-lock issue on the D7100. Solution seems to be turning the camera off, removing the lens, then remounting it and powering back on.

Change of plan

I have abandoned the D7100 idea because I have just bought a hardly used D700 (279 Shutter count). The difference in the full frame and DX size frame images is staggering, although it is only 12MP.

However I have come across one thing I cannot fathom out. If I use the built in flash it fires without a problem. If I use my seperate flashgun (I have a Sigma EF-500DG ST) it always fires the short burst of flashes which are designed to reduce red eye. I cannot figure out how to turn this off. I have been through the various custom settings and the hand book and cannot see how to do it. Has anyone any idea how I can stop this multi flash and the delay before the shutter fires. With my D90 there is no problem.

Forget the above. I have just worked it out how to turn it off simply by elimination off possibilities. The D700 is ready to roll!

I don't think you will regret that purchase. The D700 was my first full frame DSLR and the quality difference you mention is indeed staggering and gives the lie to pixel count being the all important specification when choosing a DSLR - it's the "quality" of the pixels that is all important. I've not used a DX Nikon that can approach the D700. OzJohn

 

[John_M_King]

There is a small problem involving the camera as described in the post after this, but only with a Sigma lens, however there is a way to get around it.

Ibeg to differ.theD800 is a quantum leap ahead of the D700

D800/700

Also a quantum leap in price too.

it's just money.what else are you gonna do with it?

 

[John_M_King]

Oh I have plenty to do with it, money that is. I have two BMW motorcycles to keep up to scratch and running for starters.

Apart from that I could not justify the cost of a near £2000 camera (UK Price). The quality afforded by the D700 is a massive leap ahead for me when compared to DX size sensors.

Indeed it is but this is a discussion about the 700 and that camera has been their introduction to FX for many Nikon shooters and it is a revelation after DX . OzJohn

I was disappointed by the D700 color after using the D200 which had great color accuracy for skin tones.the D800is a step up from the D700 color and just as accurate as the D200 was. thank you Nikon
